Veeam - B&R 7/8/9 stopped to work when renamed server name how to solve

With Veeam 7/8/9 B&R stop to work if you rename server.

To restore functionality you need to change and analyze these register fields putting new server name.

I suggest to eviscerate every single key, could you have more subfolder than in my case

Veeam\Veeam Backup and Replication\SqlServerName
Veeam\Veeam Backup Catalog\CatalogSharedFolderPath

\Veeam\Veeam Backup and Replication\SqlServerName
\Veeam\Veeam Backup Catalog\CatalogSharedFolderPath
\Veeam\Veeam Backup Packages\{06C5CCDE-FB93-4566-A13F-75C8A2AFABDC}\{564d7967-2024-de0e-f087-bc2e39fba624}\name

It's important that you will change registry keys that are related to sql istances:

\\HKLM\Software\VeeaM\Veeam Backup Catalog\SqlServerName (Should be local)
\\HKLM\Software\VeeaM\Veeam Backup Reporting\SqlServerName (Should be local)
