With all the issues with SMP and SMP/E themselves over the years, I always backup ALL SMPE related datasets, including the CSIs, before I start any SMPE work.
No source/object management systems are perfect and the extra time to secure a check point of the state of the SMP/E environment is well worth the effort. When I was supporting VM/PE for Amdahl, I made it a point to tell the customers to ONLY APPLY the modifications that we provided as it made future maintenance simpler. I suggest as a practice that any local modifications be APPLYed and never ACCEPTed, because, as new vendor or IBM supplied maintenance rolls out, you are probably going to have to retrofit the local changes. https://www.ibm.com/docs/en/zos-basic-skills?topic=commands-smpe-apply-command - this is a link with a diagram of the flow from RECEIVE to APPLY to ACCEPT and RESTORE. IMHO ... BACK UP ALL SMPE related datasets before you start. It will save you hours of frustration. SMP/E is a complex tool to manage your z/OS system, but it does the job it is intended to do.
