Upgrading OS from within Update Manager

Asked by William Pabon on 2012-11-21

I'm planning to upgrade my OS from 10.04 LTS to 12.04 LTS using the Update Manager as a source. This is my first time doing this. Thus, have some questions.
Is this a fairly safe way to do it?
What happens to the data that I have in my home folder?
What happens to the applications that I have installed?
My desktop GUI is Macbuntu. I suppose it will be erased. Is that so?
What other considerations I should take into account before doing this upgrade?

Thanks for your advice.

Personally I would never upgrade without backing up first. It is not common for it to go wrong but it is not unheard of either.

The upgrade will delete things that are no-longer supported but should leave most applications untouched and should not lose your home folder contents.

I usually backup the /home and /etc folders (including hidden files) before an upgrade. Just to be safe.

Sorry I missed this other concern. My mail application is Evolution (on my 10.04 OS). I have many local folders to save important emails. What would happen with this application and the local folders that I've created when I upgrade?

Your mail is stored under /home as a hidden folder

It should be OK but if not and you have backed up you can restore it.

Can you help with this problem?
