Upgrade from Squeeze to Wheezy or Jessie

[odelattre]

Hi,

I have a question : is it possible to simulate upgrading a Squeeze installation to a Wheezy or Jessie installation, on a OVH server ?

I would like simulate upgrading server, and if not problems, upgrading in real time.

I don't do that manipulation, and I don't do mistakes on a production server.

Thanks a lot.

I know that you can simulate an apt-get upgrade with the -s flag, but that won't simulate what happens after the reboot:

Code: Select all

apt-get dist-upgrade -s

Also see the Wheezy and Jessie release notes, which have upgrade notes.

For a production VPS, you are probably better off getting a new one in the desired release, setting up AND TESTING the services you use, then migrating the users across (usually with a simple DNS change).
