We want to upgrade SQL Server 2008 R2 to SQL Server 2012 sp3 on the same server A. The SQL Server 2008 R2 is on Windows Server 2008 R2 Standard and it has six user databases.
First we will upgrade Windows Server R2 Standard to Windows Server 2012 R2 Standard. Then we will uninstall SQL Server 2008 R2 from server A. We will install SQL Server 2012 SP3 on Server A and restore the backup of SQL Server 2008 R2 databases. I have script out the SQL Server Agent Jobs and linked server. So I can run after the restore.
There are only four logins. I script out the login too.
My question is: do I need to restore system databases too?
