The above should be alright provided both the primary and the standby
are down and the instructions in the pg_upgrade docs are followed.

So, start both the primary and the replica? That part should be fine by
itself.

At some later point, shut down the replica completely, then do an rsync
from that replica to the other replica and build its hard-link tree that
way, and update anything that's changed while the 'migrated' replica was
online? I don't see any obvious issue with that as the result should
mean that the two replicas are identical from PG's perspective from that
point moving forward.
Ultimately, it really depends on your specific environment though, of
course. It also might not be a bad idea to do a regular backup of the
upgraded primary and then restore that to the second replica, just to
make sure you have that whole process working and to test out your
restore process.
Thanks!
Stephen
