In addition, I would suggest running these tests before *and* after you merge your anope databases since it sounds like you are merging. One db will be on Unreal, the other on Inspircd, so you may have different results.
A TestNet is never a bad idea, even if it's on your home PC, obviously it's best in a like environment but any testing is better than no testing!
If you have any questions about db migrations, testing, setting up a testnet or the like feel free to PM me.
