Versions of what? SQL Server? If so, I strongly recommend that you bring the UAT box up to the same level of SQL Server as the Production box. If the UAT box is at a higher level, then you should either role it back to what the Production box is or, better yet, bring the Production level up to the latest SP and CU (it's important for security, as well).
