Bridge CC cache not compatible with bridge CS6

Question

Starting the Photoshop CC adventure. First install was Bridge. First test was to see if the Bridge CC cache is compatible with Bridge CS6 cache. First result is NO.
  Test method:
  1. Set the Bridge CC cache location to the same folder I use for CS6, which contains 10+ gigs of thumbs for my library.
  2. Navigated Bridge CC to a sub-folder with about 30 images, see Bridge CC re-do the thumb extractions.
  3. Close Bridge CC, launch Bridge CS6, navigate to the same sub-folder, see Bridge CS6 re-do the thumb extractions.
  4. Close Bridge CS6, launch Bridge CC, still pointing to the same sub-folder, see it re-do thumb extractions again.
  5. Repeat steps 3&4, always with same result, a redundant re-generation of thumbs.
  Conclusion:
  The actual thumbnail files in the cache are the same. But something happens in the index files (data/store) to make each version think it does not have thumbnails, so it re-generates them. IOW, when Bridge CC looks at the cache last used by Bridge CS6 it says "I have not been here, must re-cache", and visa-versa.
  Solution:
  Must let Bridge CC have its own separate cache, so the two versions don't walk over each other. Must let Bridge CC re-cache everything, which for me (and most users I assume) will be a long and time consuming process.
  Not much surprise here. The same was true for CS5 vs. CS6.

Answer 1

  Not much surprise here. The same was true for CS5 vs. CS6.
Then it also should not be a surprise for you that this behavior already started in the Filebrowser (Bridge predecessor that came with CS1 and by far the most stable and fast cache ever in the history of Bridge) and has not changed since. Nor is it likely it will chance in the future.
Hence my advice to not use Bridge for long term DAM because you need to recache the lot every new version...
