In this Post I will show you how to upgrade Veeam Backup and Replication from version 11a to v12, including database migration from SQL Server to PostgreSQL (the default database in this new Veeam release).
I used RTM version released in 30 january 2023 (I think there won't be big differences for the GA version):
- Previous Versions: 11.0.1.1261
- Upgrade Version: 12.0.0.1402
The Upgrade and Migration are done in three steps:
- Upgrade v11a to v12 including all components (console, explorers, agents and plugins);
- Database Backup and Restore from SQL Server to PostgreSQL;
- Cleanup SQL Server databases and files.
Since it will be necessary to stop services and Backup Jobs, it is convenient that this process be carried out in a period where there is no backup window. This whole process takes about 2 hours (depending on the infrastructure).
Note: I will not cover the Veeam Backup Enterprise Manager Upgrade.
Let's start!
