Depending on your current version, you might experience one or more configuration migrations, and have to consider configuration guidelines for all versions between the starting version and the ending version when you upgrade. You must manually upgrade to 7. SSH host key action required in 9. When you upgrade to 9. Moreover, if you explicitly configure the ASA to use the RSA key with the ssh key-exchange hostkey rsa command, you must generate a key that is bits or higher.

RSA support will be removed in a later release. Only SSH version 2 is supported. SAMLv1 feature removed in 9. No support for DH groups 2, 5, and 24 in 9. The ssl dh-group command has been updated to remove the command options group2 , group5 , and group No support in ASA 9. Limited support will continue on releases prior to 9. Further guidance will be provided regarding migration options to more robust and modern solutions for example, remote Duo Network Gateway, AnyConnect, remote browser isolation capabilities, and so on.

These IDs are for internal use only, and 9. For example, if these IDs are in use after upgrading a failover pair, the failover pair will go into a suspended state. See CSCvw for more information. Before you upgrade from an earlier version of ASA to Version 9. When the configuration is rejected, one of the following actions will occur, depending on the command:.

Fixing your configuration before upgrading is especially important for clustering or failover deployments. For example, if the secondary unit is upgraded to 9. This rejection might cause unexpected behavior, like failure to join the cluster. Restoration of bypass certificate validity checks option —The option to bypass revocation checking due to connectivity problems with the CRL or OCSP server was restored.

ASDM Cisco. The wizard can upgrade ASDM from 7. CSCvt As a workaround, use one of the following methods:. Note that the ASDM image 7. Save the configuration and reload the ASA. For Failover pairs in 9. Downgrade issue for the Firepower in Platform mode from 9. You either need to restore your version to 9.

This problem does not occur if you originally upgraded to 9. Note that ASDM 7. ASAv requires 2GB memory in 9. You must adjust the memory size before upgrading. Cluster control link MTU change in 9. The recommended MTU for the cluster control link has always been or greater, and this value is appropriate. However, if you set the MTU to but then failed to match the MTU on connecting switches for example, you left the MTU as on the switch , then you will start seeing the effects of this mismatch with dropped cluster control packets.

Be sure to set all devices on the cluster control link to the same MTU, specifically or higher. Beginning with 9. A CA certificate from servers issuing chain is trusted exists in a trustpoint or the ASA trustpool and all subordinate CA certificates in the chain are complete and valid. Local CA server is removed in 9. This feature has become obsolete and hence the crypto ca server command is removed.

Removal of bypass certificate validity checks option —The option to bypass revocation checking due to connectivity problems with the CRL or OCSP server was removed. Thus, after an upgrade, any revocation-check command that is no longer supported will transition to the new behavior by ignoring the trailing none.

These commands were restored later refer CSCtb They will be removed in a later release. The former default Diffie-Hellman group was Group 2. When you upgrade from a pre Because group 2 will be removed in a future release, you should move your tunnels to group 14 as soon as possible. SSH security improvements and new defaults in 9.

SSH version 1 is no longer supported; only version 2 is supported. The ssh version 1 command will be migrated to ssh version 2. This setting is now the default ssh key-exchange group dh-groupsha The former default was Group 1 SHA1. If it does not, you may see an error such as "Couldn't agree on a key exchange algorithm. The default is now the high security set of ciphers hmac-sha1 and hmac-sha as defined by the ssh cipher integrity high command.

The former default was the medium set. The default trustpool is removed in 9. As a result, crypto ca trustpool import default and crypto ca trustpool import clean default commands are also removed along with other related logic. However, in existing deployments, certificates that were previously imported using these command will remain in place.

The ssl encryption command is removed in 9. ASA X memory issues with large configurations on 9. One option is to enter the object-group-search access-control command to improve memory usage for ACLs; your performance might be impacted, however. Alternatively, you can downgrade to 9.

Before upgrading to 9. If your failover key is too short, when you upgrade the first unit, the failover key will be rejected, and both units will become active until you set the failover key to a valid value. Do not upgrade to 9. After upgrading, the ASAv becomes unreachable. Upgrade to 9. Upgrade issue with 9. ASA 9. To avoid loss of SSH connectivity, you can update your configuration before you upgrade. Sample original configuration for a username "admin":. To use the ssh authentication command, before you upgrade, enter the following commands:.

We recommend setting a password for the username as opposed to keeping the nopassword keyword, if present. The nopassword keyword means that any password can be entered, not that no password can be entered. Prior to 9. Now that the aaa command is required, it automatically also allows regular password authentication for a username if the password or nopassword keyword is present.

After you upgrade, the username command no longer requires the password or nopassword keyword; you can require that a user cannot enter a password. Therefore, to force public key authentication only, re-enter the username command:. After the reload, the startup configuration will be parsed correctly.

For a cluster, follow the upgrade procedure in the FXOS release notes; no additional action is required. For the Firepower ASA security module, the feature mobile-sp command will automatically migrate to the feature carrier command.

The following CSD commands will migrate: csd enable migrates to hostscan enable ; csd hostscan image migrates to hostscan image. ASA X and X upgrade issue when upgrading to 9. Due to a manufacturing defect, an incorrect software memory limit might have been applied. If you upgrade to 9.

If the memory shown is ,, or greater, then you can skip the rest of this procedure and upgrade as normal. We introduced or modified the following commands: ssl client-version, ssl server-version, ssl cipher, ssl trust-point, ssl dh-group.

We deprecated the following command: ssl encryption. We deprecated the following command: aaa-server protocol nt. The Auto Update Server certificate verification is now enabled by default; for new configurations, you must explicitly disable certificate verification. If you are upgrading from an earlier release, and you did not enable certificate verification, then certificate verification is not enabled, and you see the following warning:.

In order to verify this certificate please use the verify-certificate option. Upgrade impact for ASDM login when upgrading from a pre If you upgrade from a pre You must change the more command either before or after you upgrade to be at privilege level 5; only Admin level users can make this change.

Note that ASDM version 7. Select more , and click Edit. Change the Privilege Level to 5, and click OK. Click OK , and then Apply. This value does not include the Layer 2 header. ACLs not in use are removed. The any4 and any6 keywords are not available for all commands that use the any keyword. If you try to access the destination IP address on a different port not covered by a NAT rule, then the connection is blocked.

This behavior is also true for Twice NAT. Moreover, traffic that does not match the source IP address of the Twice NAT rule will be dropped if it matches the destination IP address, regardless of the destination port.

Therefore, before you upgrade, you must add additional rules for all other traffic allowed to the destination IP address. If you want any other services to reach the server, such as FTP, then you must explicitly allow them:. Or, to allow traffic to other ports of the server, you can add a general static NAT rule that will match all other ports:.

If you want the outside hosts to reach another service on the inside server, add another NAT rule for the service, for example FTP:. If you want other source addresses to reach the inside server on any other ports, you can add another NAT rule for that specific IP address or for any source IP address.

Make sure the general rule is ordered after the specific rule. Configuration Migration for Transparent Mode—In 8. When you upgrade to 8. The functionality remains the same when using one bridge group. You can now take advantage of the bridge group feature to configure up to four interfaces per bridge group and to create up to eight bridge groups in single mode or per context. Note In 8. When upgrading to 8. The unidirectional keyword is removed. See the following guide that describes the configuration migration process when you upgrade from a pre Zero Downtime Downgrades are not officially supported with clustering.

Flow offload is disabled by default for ASA. To perform a Failover or Clustering hitless upgrade when using flow offload, you need to follow the below upgrade paths to ensure that you are always running a compatible combination when upgrading to FXOS 2. For example, you are on FXOS 2. During this time, additional unit failures might result in lost sessions. Therefore, during a cluster upgrade, to avoid traffic loss, follow these steps. On the chassis without the control unit, disable clustering on one module using the ASA console.

If you are upgrading FXOS on the chassis as well as ASA, save the configuration so clustering will be disabled after the chassis reboots:. If you have a boot system command configured, remove it so that you can enter the new boot image. If you did not have a boot system command configured, skip this step.

Set the ASA image to boot the one you just uploaded. You can only enter a single boot system command. The boot system command performs an action when you enter it: the system validates and unpacks the image and copies it to the boot location an internal location on disk0 managed by FXOS.

The new image will load when you reload the ASA. If you change your mind prior to reloading, you can enter the no boot system command to delete the new image from the boot location, so the current image continues to run. Set the ASDM image to use the one you just uploaded. You can only configure one ASDM image to use; in this case, you do not need to first remove the existing configuration.

Save the new settings to the startup configuration:. The Upgrade Software from Local Computer tool lets you upload an image file from your computer to the flash file system to upgrade the ASA for the Firepower , Firepower in Appliance mode.

If the upgrade installation succeeded, for the upgrade versions to take effect, check the Save configuration and reload device now check box to restart the ASA, and restart ASDM. Click Finish to exit the wizard and save the configuration changes that you have made. To upgrade to the next higher version, if any, you must restart the wizard.

Perform these steps on the active unit. When you connect to the CLI, determine the failover status by looking at the ASA prompt; you can configure the ASA prompt to show the failover status and priority primary or secondary , which is useful to determine which unit you are connected to. See the prompt command.

Alternatively, enter the show failover command to view this unit's status and priority primary or secondary. Copy the software to the standby unit; be sure to specify the same path as for the active unit:. Copy the ASDM image to the active unit flash memory:. Copy the ASDM image to the standby unit; be sure to specify the same path as for the active unit:. If you are not already in global configuration mode, access global configuration mode:.

Set the ASDM image to use the one you just uploaded :. You can only configure one ASDM image to use; in this case you do not need to first remove the existing configuration. Wait for the standby unit to finish loading. Use the show failover command to verify that the standby unit is in the Standby Ready state.

Force the active unit to fail over to the standby unit. From the new active unit, reload the former active unit now the new standby unit. If you are connected to the former active unit console port, you should instead enter the reload command to reload the former active unit. In the Flash File System Path field, enter the path to the flash file system or click Browse Flash to find the directory or file in the flash file system. The uploading process might take a few minutes. When you are prompted to set this image as the ASA image, click No.

Upload the ASA software, using the same file location you used for the standby unit. When you are prompted to set the image as the ASA image, click Yes. You are reminded to reload the ASA to use the new image. Click the Save icon on the toolbar to save your configuration changes.

Stay on the System pane to monitor when the standby unit reloads. Copy the software to the secondary unit; be sure to specify the same path as for the primary unit:. Copy the ASDM image to the primary unit flash memory:. Copy the ASDM image to the secondary unit; be sure to specify the same path as for the primary unit:.

Save the new settings to the startup configuration. Make both failover groups active on the primary unit. Wait for the secondary unit to finish loading. Use the show failover command to verify that both failover groups are in the Standby Ready state. Force both failover groups to become active on the secondary unit:. If you are disconnected from your SSH session, reconnect to the failover group 1 IP address, now on the secondary unit.

If you are connected to the primary unit console port, you should instead enter the reload command to reload the primary unit. If the failover groups are configured with the preempt command, they automatically become active on their designated unit after the preempt delay has passed.

Launch ASDM on the secondary unit by connecting to the management address in failover group 2. Connect ASDM to the primary unit by connecting to the management IP address in failover group 1, and upload the ASDM software, using the same file location you used on the secondary unit. Upload the ASA software, using the same file location you used for the secondary unit. These configuration changes are automatically saved on the secondary unit.

Stay on the System pane to monitor when the secondary unit reloads. If the failover groups are configured with Preempt Enabled, they automatically become active on their designated unit after the preempt delay has passed.

For appliance mode procedures, see Upgrade the Firepower , in Appliance Mode. This section describes how to upgrade the ASA bundle for a standalone unit. You will upload the package from your management computer. Click Upload Image to upload the new package from your management computer.

Click Choose File to navigate to and select the package that you want to upload. The selected package is uploaded to the chassis. The Upload Image dialog box shows the upload status.

Click Yes to confirm that you want to proceed with installation. There is no indicator that the new package is being loaded. You will still see the Firepower Chassis Manager at the beginning of the upgrade process. When the system reboots, you will be logged out. You must wait for the system to come back up before you can log in to the Firepower Chassis Manager. The reboot process takes approximately 20 minutes.

After the reboot, you will see the login screen. When the new package finishes downloading Downloaded state , boot the package. In the show package output, copy the Package-Vers value for the security-pack version number. The chassis installs the ASA image and reboots. Wait until you see the following messages:. The active unit always owns the active IP address. Connect to the Firepower Chassis Manager on the standby unit. Make the unit that you just upgraded the active unit so that traffic flows to the upgraded unit.

Connect to the Firepower Chassis Manager on the former active unit. You need to determine which unit is active and which is standby. To determine the failover status, look at the ASA prompt; you can configure the ASA prompt to show the failover status and priority primary or secondary , which is useful to determine which unit you are connected to.

Alternatively, enter the ASA show failover command to view this unit's status and priority primary or secondary. Specify the URL for the file being imported using one of the following:. View the version number of the new package. Launch ASDM on the primary unit or the unit with failover group 1 active by connecting to the management address in failover group 1. Connect to the Firepower Chassis Manager on the secondary unit. Make both failover groups active on the secondary unit.

Connect to the Firepower Chassis Manager on the primary unit. If the failover groups are configured with the ASA preempt command, they automatically become active on their designated unit after the preempt delay has passed. If the failover groups are not configured with the preempt command, you can return them to active status on their designated units by connecting to the ASA CLI and using the failover active group command.

Show the current boot images configured up to 4 :. The ASA uses the images in the order listed; if the first image is unavailable, the next image is used, and so on. You cannot insert a new image URL at the top of the list; to specify the new image to be first, you must remove any existing entries, and enter the image URLs in the order desired, according to the next steps.

Remove any existing boot image configurations so that you can enter the new boot image as your first choice:. Set the ASA image to boot the one you just uploaded :. Repeat this command for any backup images that you want to use in case this image is unavailable. For example, you can re-enter the images that you previously removed. You can only configure one ASDM image to use, so you do not need to first remove the existing configuration. The Upgrade Software from Local Computer tool lets you upload an image file from your computer to the flash file system to upgrade the ASA.

You can reenable it after the upgrade:. Wait for the upgrade to complete. Reload the standby unit to boot the new image:. Wait for the upgrade to complete, and then connect ASDM back to the active unit. Perform these steps in the system execution space. Make both failover groups active on the primary unit:. Reload the secondary unit to boot the new image:. Wait for the upgrade to complete, and then connect ASDM back to the primary unit.

Wait for the upgrade to complete, and then connect ASDM back to the secondary unit. To upgrade all units in an ASA cluster, perform the following steps. Perform these steps on the control unit. You can configure the ASA prompt to show the cluster unit and state control or data , which is useful to determine which unit you are connected to. Alternatively, enter the show cluster info command to view each unit's role.

You must use the console port; you cannot enable or disable clustering from a remote CLI connection. Perform these steps in the system execution space for multiple context mode. Copy the ASDM image to all units in the cluster:. If you are not already in global configuration mode, access it now. Show the current boot images configured up to 4.

Note the cluster-pool poolname used. During the upgrade process, never use the cluster master unit command to force a data unit to become control; you can cause network connectivity and cluster stability-related problems.
