Using pg_upgrade takes minutes for an in place upgrade. If you can allow 1+ hour of downtime, it seems overly complicated to use logical replication.

I suppose the Atul's issue is what to do with the replicas. Once he does pg_upgrade, then he will need to provision new ones, no? I suppose in this case logical would be better, with the new instance itself having replicas. I haven't done it, and it's gonna require some setup time, definitely much longer than pg_upgrade then make do with one server until your new physical replicas are set up.
