Upgrading the CLM system

Purpose

This chapter describes the steps that must be performed in order to upgrade the CLM.

Note: Ensure that the old CLM is running during the upgrade.

Steps
Install the new CLM
 
1 

Install the new CLM as described in Chapter 10, CLM system installation

Back up the existing CLM
 
2 

To manually backup the contents of the PostgreSQL database, do the following:

  1. Log in to the pre-24.11 primary CLM server as the nsp user.

  2. Enter the following:

    nspdctl --host IP_address backup -d nspos_migration -f ↵

    where

    IP_address is the IP address of the desired CLM server

  3. Verify that the backup has completed successfully. Execute:

    nspdctl --host IP_address backup status ↵

    where

    IP_address is the IP address of the desired CLM server

Transfer the backup to the new CLM deployer host
 
3 

Transfer the backup file to the CLM deloyer host:

scp /opt/nsp/backup/nspos_migration/nspospostgresql_backup_timestamp.tar.gz root@<deployer ip>:/root/

where

timestamp is the backup creation date and time

Restore the CLM portion of the database
 
4 

Enter the following on the CLM deployer host:

# cd /opt/nsp/NSP-CN-DEP-release-ID/NSP-CN-release-ID/tools/database ↵

5 

Note: In a DR deployment, you must perform the steps in the data center that is the pririmary data center.

Enter the following to restore the CLM PostgreSQL database:

# ./nspos-db-restore-k8s.sh license-manager backup_dir/backup_file ↵

where

backup_dir is the directory that contains the backup file

backup_file is the backup file name, for example, for PostgreSQL, the name is /root/nspos-postgresql_backup_timestamp.tar.gz

End of steps
