Thanks for your input.
Your suggestion is
*option#1*
ASIS-existing server = EC2 with Community PostgreSQL Ver 13.16.2*
- ensure to capture all the pre.req meant for ver 15.10 are being met.
- enable logical replication tagged to proposed new EC2 server
No, logical replication != pg_upgrade process.
(with newer Higher OS Version ).
Proposed-new EC2 server (with new Operating System version along
Postgres Ver 13.16.2 and 15.10 Binaries)*
- install postgres 13.16.2 binaries
- have postgres setup on par with existing setup and having proper
logical replication
Again, no.
- install postgres 15.10 binaries
- ensure to DISABLE auto startup and shutdown of postgres 13.16.2
- ensure to DISABLE auto startup and shutdown of postgres 15.10
- start postgres db ver 13.16.2 and ensure all are good. no errors
in postgres log file
- start performing pg_upgrade step to upgrade postgres from ver
13.16.2 to 15.10
pl Vet the newer steps (revised version).
I don't know how much clearer it can be, follow the step by step
instructions shown here:
https://www.postgresql.org/docs/current/pgupgrade.html
"These are the steps to perform an upgrade with pg_upgrade:
[...]
"
