Ahh, Matthias has just reminded me that 1.7 is being released before
the new persister, and so will be able to use the persister.log file
from 1.6 installations. So far, there have been no reasons to change
the mnesia schema either so unless that changes between now and 1.7
being released, then you should be able to upgrade seemlessly.

My comments above really refer to when the new persister gets released.

Sorry for creating confusion.
