[ubuntu] Ubuntu 12.10 update > Need of manually updating external PPAs?

view story

http://ubuntuforums.org – Hello dear Ubuntu users, If I update to Ubuntu 12.10, do I have to (manually) update external PPAs as well? For instance, I have some PPAs from webupd8 in my repositories. But they were meant for 12.04, right? So I assume I have to update the repos as well. Or is Ubuntu 'smart' enough to update these as well and replace 'Precise Pangolin' with 'Quantal Quetzal' in all the repo names? Also, before updating - do I have to disable the external repos? I just want to make sure that nothing goes wrong during the update. Thank you in advance :popcorn: (Hardware)
