Ron/AdrianThanks 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 (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
- 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).
