So interesting point to be made here - I just migrated the AD CA from Windows Server 2012 R2 to 2019. The issue came up when I restored the CA database and it was giving me a "The Expected Data does not exist in this directory. Please choose a different directory. The system cannot find the file specified. 0x80070002 (Win32:2 Error_File_Not_Found)". The fix... after much banging head on wall is to go to the directory right above the "Database" folder and select that then it will let you proceed.

Am I correct in understanding the backup of the CA does not backup manually created certificate templates? Planning on upgrading from 2012 to 2022 server and want to make sure I don't lose the templates we have, thanks for the guide!

You missed a step to modify the BCAServerName in the Configuration key settings from dc.lab.local to dc1.lab.local

When migrating the CA, does the FQDN of the new server have to be the same name of the old CA server?

What if the new server is having different name from the old one?

is it possible to Migrate Certification Authority to Another Server without uninstalling the old CA server services. or is it possible to create new CA server because the old CA server is no longer possible to retrieve. Thanks
