I'm planning an update from SQL 2008 to 2012. I have a very heavy workload where most of the work is done using automatic processes (99.5%), and I would like to test all automatic processes before upgrading. I wanted to replay traces on TEST. when I upgraded from SQL 2000 to SQL 2008 I tried to use Profiler replay but it had so many issues that I just had to put a lot of effort in it in order to make it run, and eventually it didn't give me any usable results as it failed on many things (first on wrong DB_ID, then I had to recreate the whole environment (50 databases) back to the original point to time in order to run the traces on the right state) and so on.
I wonder if any body has experience with the Distribution Replay utility, and if it is a recommended tool to use.
