You will need to run a query against the Veeam SQL Database to “break” the connection from VBR to Enterprise Manager.
In order to do so we will need:
- SSMS: https://docs.microsoft.com/en-us/sql/ssms/download-sql-server-management-studio-ssms?view=sql-server-ver15
- Using SSMS connect to the SQL server holding the Veeam DB(you can find all the details on the Veeam server using regedit – Go to HKLM\Software\Veeam\Veeam Backup & Replication\ // There you have 3 keys: SQLDatabasename, SQLInstancename and SQLServername)
- First Backup the Veeam SQL DB: https://www.veeam.com/kb1471
- After DB Backup please run the below Query against the Veeam DB exactly as it is, without changing any values in the query(default name for Veeam DB is “VeeamBackup):
update dbo.options
set value = ‘<EnterpriseServerInfo><IsConnected>false</IsConnected><ServerName></ServerName><Url></Url></EnterpriseServerInfo>’ where name = ‘enterpriseserverinfo’
After the above Veeam should not see any more the connection to “ghost”/old Enterprise Manager.
