Upgrade from 13.0 to 13.5

Issue/Introduction
We are looking at upgrading from 13.0 to 13.5.
There do not seem to be any structural changes for the SYSCHK1 datasets or OPSLOGs, so upgrading to 13.5 and backing out to 13.0 does not require anything special to move between these releases?
Best Practices indicates: "Verify your product JES2 offset table corresponds to JES2 on this system." How do we verify? We no longer assemble the OPJ2CB module.
Environment
Release : 13.5
Component : OPS/MVS
Resolution
The upgrade from OPS 13.0 to 13.5 should be smooth:
- you can use the same OPSLOG and SYSCHK1 datasets
- going back to OPS 13.0 from OPS 13.5 should not be a problem either, you can still use the same OPSLOG and SYSCHK1 files
The backup of the SYSCHK1 dataset is always a good practice even upgrading or reverting but you should not need to use it.
Regarding the JES2 interface, you just need to make sure you have the required maintenance to support the z/OS release that is currently running. We no longer assemble the OPJ2CB module. Please, visit the OPS compatibility matrix and make sure you apply all required maintenance for the z/OS level and also for other products/interfaces you may use:

If you have the maintenance required to support the current z/OS release there shouldn't be any concerns regarding the JES2 interface.
Lastly, I have 2 additional recommendations:
1) Apply all maintenance published for OPS 13.5 or at least the HIPER PTFs listed below:

2) A recurrent problem during upgrades is the usage of mixed releases of OPS modules. For example, if you put the OPSAEX module in the LPA, make sure you refresh this module so that the correct release is used when upgrading or reverting. If you don't put this module in the LPA (this is not required) then you just need to pay attention to the LNKLST and/or STEPLIBs. Also pay attention to the libraries allocated to TSO/ISPF to make sure they are from the correct release.
