The storage nodes don't change.  The tracker is the versioned part.
Granted, there are some changes to the 2.0 mogstored storage daemon,
but none that are required AFAIK...

I -think- it's possible, yes, but I wouldn't recommend it.  v2
requires some database changes that may not be best to make while
you're still using some v1 trackers?

As it stands, v2 has been in use for quite some time, and in
production on many sites.  I'm pretty confident in recommending you
upgrade.  Of course, I also suggest you have a backup of your
database, but that's just a good idea anyway regardless of what
version of MogileFS you run!
