Upgrading Ubuntu 10.04 to 12.04 - Anything to look out for?
I have a Linode 512 happily running Ubuntu 10.04 LTS. I want to upgrade to 12.04 LTS because I need a newer PHP to run Symfony.
I'm reading this:
and
For those who have done it recently, are there any gotchas that I should look out for?
I don't think I have anything particularly unusual running and anything critical has come from apt-get.
I have the Linode backup service so I will make a snapshot first.
I don't know why I thought this but somehow I had the impression that a clean install was only good way to go but upgrading certainly seems like a reasonable and much easier option.
Thanks

Now your new Linode will be running 12.04 and acting as your server. Once you're satisfied everything is OK, remove the old Linode. You'll be billed a little extra since you'll be running two Linodes instead of one for a day or two, but since charges are prorated it's not much of an expense.
The backup, upgrade, restore-if-a-problem-occurs method also works, but at the risk of more downtime.
