Required PUM updates for 8.53 - 8.56

Hi -

Looking to move from 8.53 to 8.56.

Looking at PUM23 am I correct in assuming that at a minimum I need to pull a package of objects using Tracking Group = PeopleTools Compatibility and value of "Required for PeopleTools 8.55"?

I'm guessing PI23 wouldn't have any required for PT 8.56 objects yet anyway so applying the 25 objects that it found using "Required for PeopleTools 8.55" should allow us to go to 8.56 at a minimum and then we may need to look at a newer PI for any required objects to go to a later 8.56.xx patch level.

The last full PI we applied was 16.  I at first created a very large package from PI23 containing ALL missing objects - however I'm seeing that contains some objects referencing other objects (app packages, messages, etc.) that we cannot get because we did not meet the min PT requirements for them to be included in the package.
