We've been preparing for more than a month, and we've done it before.

It's a pain to keep two repositories in parallel. I, personally, will  
not volunteer to do that work.

Yes, of course. We've converted several repositories before,  
including Boost. Up until yesterday, we had a full Boost SVN+Sandbox  
SVN+Trac running on the OSL servers for testing purposes...  now,  
we're preparing to move the sandbox. I'll send an announcement for  
the sandbox switchover "soon".

Most of the work is done. When we're ready to switch (and *after*  
1.34.0 is out the door), we'll ask for a 24-hour window to make sure  
we have enough time for the cvs2svn conversion and import (roughly 8  
hours of crunching), and to deal with any issues that might crop up.
