Main reason is up to date php

Can this be done with out any downtime and hassel free ?


There are instructions here on upgrading Debian 5 to 6 (though, note that Debian 7 is about to come out):

Can it be down without hassle and/or downtime?

Well, that’s a tall order :slight_smile:

I’d highly recommend performing the upgrade on a test server, prior to attempting it on your live server.

It takes a lot of testing and preparation to get to a point where there’s minimal downtime.

But upgrading from one distro to another is a big deal, and there’s plenty of opportunity for things to go wrong. The more planning, testing, and preparation you perform, the less likely you’ll be to experience significant downtime.

When I do upgrades like that, I would generally plan for it to be at night, during a time when users wouldn’t normally be using the server. And then, if something does go wrong, it’s less likely to be immediately noticed.


Thanks Eric,
Yes some downtime during the night is ok, these are nice instructions so perhaps I will just do this myself :slight_smile:
