[mythtv-users] Updating Mythbuntu 9.10 To 10.04 With JYA's Repository?

[nospam312]

Apologies if a simple question but I am currently running Mythbuntu
9.10 with JYA's repository.

When 10.04 is released I plan to click the Automatic Upgrade button in
Software Update.

Will having JYA's repository pointing to the "old" version cause problems?

Should I remove JYA's from Software Sources before upgrading?

Thanks
