hi,
We are planning to upgrade to SQL 2012 from 2008r2. While doing so we want to do structure and data compare between 2008R2 database and 2012.
One of our developer suggested to restore 2008R2 database to 2012 twice one with compatibility mode of 2008R2 and other to 2012. I do not think it was a good idea, cause once database is restored to 2012 it is a upgraded database even if i set compatibility mode to 2008r2 level.
My suggestion was to have 2008r2 on its own instance and use linked server or sql redgate like tool to do a compare.
Can anyone suggest few more points related to caveat in this approach, or is it ok to follow this approach? Thank you.
