Hi Jon,

i have identified the problem, the fix will be in next release of the "migration tool" but you can workaround it too:

Change the "class" of the extNonFreeFSStorage to the "org.abstracthorizon.proximity.storage.local.WritableFileSystemStorage"

The tool was (up to now) scanning only for this class, but as i see, you have used "org.abstracthorizon.proximity.storage.local.ReadOnlyFileSystemStorage" for this storage, hence the tool was not finding it

This is no longer occurring, and was fixed with Beta 3. Closing.
