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.
