Upgrade from 8.4

От

Дата:

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

Yes, PostgreSQL 9.2 would be an excellent choice; There are various upgrade options available like dump/restore, slony and pg_upgrade where each have their pros and cons. The selection of upgrade method solely depend upon the data size and available downtime. It's strongly recommended to test upgrade method before live implementation.

I recently upgraded from the 8.2 branch to 9.2.  Since mine was so old the only option I had was the dump/restore functionality, but that's really a simple procedure, just potentially time consuming based on your data and computers.  It's also good to look over the release notes between the versions so you can identify parts of your code (if you use things like plpgsql).  Doing a full dump and restore to a new version can point these issues out, and you can properly test your applications and scheduled tasks against your new server before taking the plunge.

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

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.
