The DB size is around 11-12 GB. Yes I am planning to take a downtime for upto 1 hour if required. I would like to understand the rollback steps if things go murky.
Thanks, Rajiv

I am planning to upgrade my Postgres DB server from v8.4 to a newer version. Should 9.2 be a good choice for upgrading, it has the best features around replication. Also can someone help me with a guide for the upgrade process and rollback process in case anything fails.
Thanks, Rajiv
Hey,
you haven't told us anything about your database size or if any downtime is acceptable, generally a pg_dump and reload should work without any problem but it requires downtime,if you need more specifics you should give us more details.
