Thanks for both replies.

i have gone down the route of removing all sources manually then cleaning db's on each.

My folders are all organised neatly.

As i have done this what shall i do with the thumbnail folders on each client pc? Just leave them?

Cleaning db's was an unnecessary step, this only cleans the local db, which you can throw away anyway once your central db is set up.

Artwork is still stored locally and managed via textures*.db.
Not sure, but chances are that moving from a local db to a central db creates duplicates of all your artwork.

To start of clean, I'd remove the thumbnails and textures*.db and let it rebuild, or use the artworkcleanup addon to do it for you. First option is probably quicker in this case.
