upgrade from Ubuntu 14.04 - developer branch to stable?

[smakme7757]

My current mail server is running on a very old version Debian which I'm planning on rebuilding.

Ubuntu 14.04 is about 2 weeks away and I'm considering building up the new mailserver on that platform. If i start building the mail server now it will most likely take a week or two before I'm ready to put it into the DMZ and make it ready for action.

If i install the current daily snapshot of Ubuntu 14.04 is it possible to just do an:

apt-get update && apt-get upgrade && apt-get dist-upgrade

On the 26. of April when the final build is released publicly to get me into the stable branch?

I've never done it, but that should work. My only question is the upgrade section. Is that necessary when doing a dist-upgrade?

I'm not sure i need to do it, but i always have. I have no idea why. From memory i always thought dist-upgrade refreshed all dependencies on the system.

However i could be wrong.

But I'll go agead and build up my new mail server on Ubuntu 14.04. It's past the RC scheduled date of april 10th, so it should be pretty stable.

The big difference is that dist-upgrade will REMOVE packages that are conflicting if it will allow for more important packages to be installed.

Regular upgrade, will never remove any packages.

Ok thanks, that's good to know .

Maybe specifically Ubuntu, and Debian stable, but otherwise, an upgrade can gut your system if you aren't paying attention. I'm only noting this cause there's nothing intrinsic in upgrade that protects packages, only the policy set by the specific distro.
