The only relevant component for this issue is OSDs. Upgrading the
monitors first as usual is fine. If your OSDs are all 12.2.8, moving
them to 12.2.10 has no chance of hitting this bug.
If you upgrade the OSDs to 13.2.2, which does have the PG hard limit
patches, you may hit the bug as noted here:

On mixed node environment, does it matter what role ceph component has, in terms of updating them all to 12.2.10.
I have monitor nodes at 12.2.9 and OSD nodes at 12.2.8. I am preparing to upgrade to mimic 13.2.2 and will be running dist-upgrade+reboot prior to upgrade to 13.2.2, that would move them all to 12.2.10.
Is that ok?
And should I still update my monitor nodes first to 12.2.10 and then OSD nodes to 12.2.10?
Thank you,

I'd suggest upgrading everything to 12.2.10. If you aren't hitting
crashes already with this mixed 12.2.9 + 12.2.8 cluster, a further
upgrade shouldn't cause any issues.
