Upgrading from F7 Test 4 to Released version

[Eric]

I am installing Fedora 7 Test 4 on VMware 6.0 from the torrent dated 26 
April 07, and will be doing a full system update using Software Updater 
when the installation is finished.

Assuming all that works (and results have been variable over the last 
couple of days using VMware 5.5), when the released version of F7 comes 
out, is it likely I'll need to re-install from the ISOs that come out at 
that time, or will I be able to build a fully up to date system using 
Software Updater from Test 4?
