If it happened Error 1327.Invalid Drive when you tried to upgrade Veeam Backup & Replication to 11a, don’t panic, this is likely caused by a stale registry entry for the Veeam server. In my case, the Veeam server had a F drive but removed it long time ago. My error message is Error 1327.Invalid Drive F: and upgrade failed.

Today, I am going to show you how to fix it.

1.login to Veeam management server.

Right-click Start , then select Run. Type regedit in the Open: box, and then select OK.

3. check the following registry path on the Veeam server. HKEY_LOCAL_MACHINE\Software\Veeam\Veeam Backup and Replication\ as well as HKEY_LOCAL_MACHINE\Software\Wor6432Node\Veeam, do either of these paths show the F drive? Likely it will be the VBR catalog folder in my case.

4.Right-click CatalogPath, select Modify.

5.Change the Value data from F:\VBRCatalog to C:\VBRCatalog, click OK.

6.Re-run upgrade again, the error message should be gone.

Hope you enjoy this post.
