Hi all,I have several servers running with Postgresql 7.4.x on Debian, everybody says that those servers should be migrated to version 8.0 or 8.1. Finally I'm decided to migrate those servers but I'm worried about how to do that. Those servers are in production and the downtime should be the minimum. Any advise about what's the way or the best way to do it?
Thank you very much -- Arnau
