lgtm
but be aware, if your FAS currently has high CPU-utlitization this will not improve things... the CPUs in FAS25XX are just too slow / not enough cores for all the additional features and background processes added with the newer ONTAP-versions

but FAS25XX is EOS anyways, so...

Is it a general recommendation to upgrade first to the latest P release before moving on to a new Major release?
Don't think I've seen that in the Upgrade advisor.

It's mentioned here: https://docs.netapp.com/us-en/ontap/upgrade/concept_upgrade_paths.html#types-of-upgrade-paths
"It is a best practice to upgrade first to the latest patch release in the same ONTAP release family and then upgrade to the next supported major release. This will ensure that any issues in your current version of ONTAP are resolved before upgrading.
For example, if your system is running ONTAP 9.3P9 and you are planning to upgrade to 9.11.1, you should first upgrade to the latest 9.3 patch release, then follow the upgrade path from 9.3 to 9.11.1."
