First, you need to start using standard terminology. SIT for CICS refers to the System Initialization Table, and there's only one of those per CICS region -- so you cannot have "80 CICS regions in SIT" as you posted. Furthermore, the only UAT I'm familiar with is User Acceptance Testing, and how does that fit with your posted statement "70 CICS regions in UAT"? Terminology is critical in IT, where similar terms may mean very different things, and you creating your own terms for things is NOT the way to get help on a public forum -- especially when the terms you're using already have standard meanings.
Second, cleaning up CICS regions requires you -- or somebody at your site -- to identify who (programmers and applications) are using a particular region, and determine whether or not that region could be removed, or combined with another region. How this is done, and which regions can be deleted versus combined, will ENTIRELY depend upon site procedures, standards, and management. Nobdoy at this forum could possibly come up with this information for you -- only somebody working at your site can do this.
