Обсуждение: Best way to migrate a 200 GB database from PG 2.7 to 3.6
Dear List, I need to migrate my database from a 2.x to 3.x. Usually Im using pg_basebackup , but this is not possible with different versions. Pg_dump seems to be an option but it is slow like hell and I dont want to stay offline all the time. Is there another possibility to migrate a database with 200 GB ? Thanks a lot, cheers Filip

Those version numbers aren't correct... current PG major versions run from 9.0 to 9.4. I don't think there was ever any version less than 6 (though I could be wrong).

What do you mean version 2 or 3? Maybe use replication? http://www.slony.info/documentation/1.2/versionupgrade.html Or something similar? -Andy

That said, pg_upgrade is the way to do this as long as you can have an outage.
