Re: Upgrading from 7.4 to 8.2

Hi!
Thanks for your replies!

My problem is that I want to move the DBM to a different machine so now when it doesn't seem to be any easy/trivial way to migrate from 7.4 to 8.2 I might consider to continue with 7.4.

If I decide to continue with 7.4 I guess the procedure to move the DATADIR to the new machine and then start the postgresql server there with the old DATADIR should work without problems?

Thanks, again!
