Not that I know of.
But it should be possible in the following way:
a) copy all images from 0.9.2 folder to the svn-folder
   (digikam is assumed to be not running). Use `cp -rp`
   to preserve rights etc.
b) start svn digikam so that all images get integrated into the database.
   leave digikam
c) Now the hard part is to write a script which
   for each of the new images
   - finds the database entries which are associated with it
     in the 0.9.2 database
   - adds those entries to the svn database
d) start svn digikam and all should be fine ;-)

Maybe cdigi

could be used to extract the data?

I know, this is not a simple out of the box solution as
it requires to write the script. Morever, I have
to admit, that so far I have only used the database
to read properties, but never used it to add new stuff ...

Best, Arnd
