No. Sorry for the confusion. Here is what I know. My dev SQL Server has SP3 and a security update on it to make it 9.00.4053.00 SP3 Enterprise Edition (64-bit) 3. I think that is all.

Here is what I want to know. Is it possible that the previous DBA installed another CU or Patch in between SP3 and the Security update? For example, did the previous DBA install SP3, CU2 and then the Security update or just SP3 and Security update. (I think the SP3 and Security update is correct.) My fear is that somehow I miss a CU or patch and then my Production doesn't match my Dev.

Does that make sense? If not, please let me know and I will try to explain it better.
