Hi People,

I'd like to know if it is possible to make the DB replication between sites with different version of SQL Server 2008 like the following:

Production site: Active-Passive SQL Server 2008 R2 SP1
DR site: Active-Passive SQL Server 2008 SP2

if that is not possible can I actually install two types of SQL Server in the DR sites same servers as a cluster ? so it will be like:
DR site:
Active-Passive SQL Server 2008 SP2 - Instance1
Active-Passive SQL Server 2008 R2 SP1 - Instance2

and also if I patch one of the DB 1 within the Production instances SQL Server with SP1 does that affects the other instance as well ?

Production site:
Active-Passive SQL Server 2008 R2 SP1\Instance1\DB1
Active-Passive SQL Server 2008 R2 SP1\Instance1\DB2

Thanks.

You want all of your SQL Boxes to be the same SP level as much as possible.

I would very carefully read the following chart to insure that you are able to complete the task with your version of SQL server:

More information on Active Passive, etc.

Here is a Word Doc that goes into more detail for you for SQL 2008..
