will upgrading to 9.10 changes the existing softwares/settings?

Asked by kumar

I am right now working with ubuntu 9.04 but want to upgrade to 9.10.. i have downloaded the iso file from ubuntu site.. now if i upgrade with this iso file(either through usb or cd/virtual cd), will all my existing setting, softwares etc. remain unchanged.. i am not that familiar with linux so it has taken a long time for me to configure or tweak the system/softwares according to my needs, so i don't want to go through all over again... if needed i also have an option to go through network upgrade although that will involve again downloading approx. 700 mb through terminal.. thanks..

Yes - do the network upgrade. You should have an option to upgrade when you start the Update Manager. If not, run gksudo update-manager -d from a terminal.

Your software should come through with the same settings.

Only if you downloaded the "alternate" ISO.

You could also back up your data (everything in /home/), then do a full install using your downloaded ISO.

Backup is a 'must' anyway while updating, upgrading or whatever daily procedure.

9.10 (Karmic) had some major changes.

If there is a separate /home partition it can be just kept during new installation by choosing manually partitioning and not formating it.

#4
A normal network upgrade wont usually change a separate /home partition.
Of course application version change and so may config files and/or the path of it.
But e.g. customized themes which are in /home/user_name/.themes wont change.
