Two SQL versions installed - How to manage?

Hi everyone,

I started working with NAV 2009 R2, having SQL Server 2005 SP3 installed…
Today, I installed SQL Server 2008 R2.

I wanted to ask how can I , from now on, when I need to restore a backup, select which SQL Server to use???

And what about the existing databases (in SQL Server 2005)??? Shall I simply restore them again in SQL Server 2008???

You can restore older version DB i.e 2005 directly on Sql Server 2008. It will work.

While creating new database you need to manually give Server name so you can enter either SQL2005 or SQL2008
