I agree about switching just after a release, but it's not ready for 
primetime yet IMHO.

Firstly, I think most on this list are unaware just how hideously 
difficult Boost2Git has become. Every time you think you're getting 
closer to done, another new minefield of subtle issues appears which 
causes more borkage across the whole conversion process. Dave and 
Daniel absolutely deserve a huge round of applause for wrestling that 
bull out of its china shop.

I would really *strongly* advocate a period where the SVN repo is 
used for write only, but the git repos are used for everything except 
writes. Boost2Git has been designed exactly to do that. We should 
take advantage of it.

Such is the need for proper testing I would also expect such a test 
period to last at least two Boost releases. More, if people want all 
of sandbox working perfectly.

I also think this list's opinion on Boost2Git's readiness is 
insignificant compared to Dave's and Daniel's. I only messed with the 
conversion code for a short while, and I came away feeling awed.
