This article documents the procedure for upgrading the underlying SQL Instance that Veeam Backup & Replication uses for its configuration database.
Upgrading the SQL Instance used to host the Veeam Backup & Replication configuration database is entirely optional. This procedure is intended for those customers who want to update/upgrade the SQL instance or are mandated to upgrade by their company's security policies.
On the Veeam Backup Server, open the Veeam.Backup.DBConfig.exe utility.
While the DB Config utility is usually used to change which database is used, initially, it will show you the currently configured database connection details. After you have gathered the information needed to identify the location of the SQL Instance, the utility can be closed without making any changes.
Ensure that the version being upgraded to is compatible with Veeam Backup & Replication:
Veeam Backup & Replication System Requirements > Backups Server > SQL Database
It is highly advisable to create a Configuration Backup so that if anything goes wrong, you can restore or roll back the Veeam Backup & Replication configuration.
