To install/upgrade NetBackup Snapshot Manager in docker environment

1. Download the NetBackup Snapshot Manager upgrade installer.

   Example: NetBackup_SnapshotManager_<version>.tar.gz

2. Un-tar the image file and list the contents:

   # ls
   NetBackup_SnapshotManager_11.1.x.x-xxxx.tar.gz
   netbackup-flexsnap-11.1.x.x-xxxx.tar.gz
   flexsnap_preinstall.sh
   

3. Run the following command to prepare the NetBackup Snapshot Manager host for installation:

   # sudo ./flexsnap_preinstall.sh

4. Upgrade NetBackup Snapshot Manager by running the following command:

   # flexsnap_configure install

   The installer first loads the individual service images and then launches them in their respective containers.

5. (Optional) Run the following command to remove the previous version images.

   # docker rmi -f <imagename>:<oldimage_tagid>

6. To verify that the new NetBackup Snapshot Manager version is installed successfully:

   See Verifying that NetBackup Snapshot Manager is installed successfully.

To migrate NetBackup Snapshot Manager in Podman environment

1. On the RHEL 7.x host, verify that there are no protection policy snapshots or other operations in progress and then stop NetBackup Snapshot Manager by running the following command:

   # flexsnap_configure stop

   The NetBackup Snapshot Manager containers are stopped one by one. Messages similar to the following appear on the command line:

   Stopping the services
   Stopping container: flexsnap-agent.8f9ee77e48964e278a0367e60defdf6e ...done
   Stopping container: flexsnap-workflow-system-0-min ...done
   Stopping container: flexsnap-workflow-general-0-min ...done
   Stopping container: flexsnap-listener ...done
   Stopping container: flexsnap-nginx ...done
   Stopping container: flexsnap-notification ...done
   Stopping container: flexsnap-policy ...done
   Stopping container: flexsnap-scheduler ...done
   Stopping container: flexsnap-onhostagent ...done
   Stopping container: flexsnap-agent ...done
   Stopping container: flexsnap-coordinator ...done
   Stopping container: flexsnap-api-gateway ...done
   Stopping container: flexsnap-certauth ...done
   Stopping container: flexsnap-rabbitmq ...done
   Stopping container: flexsnap-postgresql ...done
   Stopping container: flexsnap-fluentd ...done

   Wait for all the NetBackup Snapshot Manager containers to be stopped and then proceed to the next step.

2. Migrate the NetBackup Snapshot Manager configuration data to the RHEL 8.x and 9.x host:

   • If you have created a new system with RHEL 8.x and 9.x:

     • Run the following command to unmount /cloudpoint from the current host.

       # umount /cloudpoint

     • Detach the data disk that was mounted on /cloudpoint mountpoint.

       Note:

       For detailed instructions to detach or attach the data disks, follow the documentation provided by your cloud or storage vendor.

     • On the RHEL 8.x and 9.x host, run the following commands to create and mount the disk:

       # mkdir /cloudpoint

       # mount /dev/<diskname> /cloudpoint

       For vendor-specific details

       See Creating and mounting a volume to store NetBackup Snapshot Manager data.

   • If you have upgraded from RHEL 7.x to RHEL 8.x and 9.x, copy the /cloudpoint mountpoint data from RHEL 7.x system and move it to the RHEL 8.x and 9.x system under /cloudpoint folder.

   Install the same version of NetBackup Snapshot Manager on the different host (RHEL 8.x and 9.x) as on the previous host by following the steps mentioned in the To install/upgrade NetBackup Snapshot Manager in docker environment.

   This concludes the NetBackup Snapshot Manager migration process.

   After migration, install the new_version on the new host by following the steps mentioned in the To install/upgrade NetBackup Snapshot Manager in docker environment.

3. During migration process, if NetBackup Snapshot Manager is migrated to another system or IP address is changed, then regenerate the certificates as follows:

   Using flexsnap_configure CLI

   • Stop the NetBackup Snapshot Manager services using the following command:

     # flexsnap_configure stop

   • Regenerate the certificates using the following command:

     # flexsnap_configure renew --help

     Note:

     Ensure that the value of CLIENT_NAME in /cloudpoint/openv/netbackup/bp.conf file matches with Snapshot Manager hostname. In case of migration if hostname changes then this value must be manually updated before regenerating the certificates.

   • Start the NetBackup Snapshot Manager services using the following command:

     # flexsnap_configure start

4. After migrating NetBackup Snapshot Manager to a RHEL 8.x and 9.x host, perform the following steps to upgrade NetBackup Snapshot Manager to 11.1.x.x.xxxx.

   See Upgrading NetBackup Snapshot Manager.

5. This concludes the migration and upgrade process for NetBackup Snapshot Manager. Verify that your NetBackup Snapshot Manager configuration settings and data are preserved as is.
