Hello experts,
Looking for advise/suggestions on the following scenario.
Existing Setup Moving to
Postgres => 10.5 Postgres => 12.4
Ubuntu => 16.04.5 Ubuntu => 20.04.1
Question:
We have new environment ready with PG 10 & PG 12 with Ubuntu 20.
To reduce the upgrade time, can I bring the volume(10/main) from old
server to new server & connect to PG10 and do the pg_upgrade ? will
PG10 running on "Ubuntu 16" work on "Ubuntu 20" for upgrade to PG12 ?
or I have to go thru pg_dumpall route.
Thanks in advance,
Rgs,
Sushil
