[Radiant] Upgrading from 0.6.9

[Robert Wenc]

I'm trying to upgrade a old site form Radiant 0.6.9 to 0.9.1.  I've
installed the new gem, and run the rake update task in the project.  I
had some errors with extensions, but managed to get by that by
disabling them.  Everything looked good until I run the db:migrate
task.  It runs to completion, but it wipes out the whole database.
Advice? thoughts? Any help would be appreciated.
