Testing F9 - what happens when it goes final?

[Steve Dowe]

Hi,

Sorry if this is a totally lame question, but I'm currently "testing"
(ok, informally trying it out) and can't find an answer on this:

According to the release schedule
(http://fedoraproject.org/wiki/Releases/9/Schedule) the Fedora 9 beta
packages get branched on 8 April.  When this happens, does that mean
it's possible and/or standard practice to change repository location(s)
in yum and continue to update packages, or do the snapshots, preview and
final releases each require a total reinstall?  Sorry for being so
naive..!

Thanks,
Steve
