[gptalk] Default Domain and Default DC GPO migration

Here's a question for either those more knowledgeable or with a more robust 
testing infrastructure.

I'm at the start of migrating my environment to Server 2008.  Although not 
necessary, I've spent some time converting most of my GPOs to the ADMX format 
for the decrease in space usage and bandwidth usage during replication.  I now 
only have the default domain and default dc GPOs left.  I know that after the 
migration, these two will remain as ADM files.  Here's my question:  After I 
have my DC's upgraded to 2008, if I then run dcgpofix /ignoreschema, will the 
GPO's be recreated as ADMX or ADM?  My other idea was to create a temporary 
test domain with a single 2008 VM DC, just to back up these two in ADMX format, 
then delete the original ADM ones from my production domain, restoring the ADMX 
ones from the test domain.  If anyone has a better plan for switching these 
without messing up the special properties associated with them, I'm open to 
suggestions.
