We are planning to upgrade one of our Server that runs as our SQL Server 2012. Currently it has Server 2008 R2 Std as the operating system and we wanted to do an in-place upgrade to Server 2012 R2 Std.
One of the question I do have is when I do the in-place upgrade, do I need to un-join that server to our Domain then do the in-place upgrade then re-join it to the domain?
Will there be any issues doing an in-place upgrade for an SQL server?
