Are Previous Microsoft SQL Installations Needed After SQL 2012 Upgrade?

Question

Are the older installations of Microsoft SQL Server needed after you installed Server 2012? I've been doing some cleaning and noticed I've a whole list of SQL Server installation.

When I installed Server 2012, I clicked the upgrading option but previous versions are still present. I'm guessing they are needed but I want to be sure.

This is a hard question. Many of us keep the older instance running for some reason or another.

The safe path is, when done with the older stuff, to:

1) Stop and disable the services from the older version 2) Check the search path for the OS, make sure it just references the new SQL Server

That said, I expect it is safe to uninstall the older SQL versions.

I need 15 points for that, and I don't have that yet on serverfault ;) – reaper_unique May 23 '12 at 14:26
