Hi Tieku, I love to see posters answer their own questions : ) In theory, there should be a direct upgrade path from any version that is still in CHANGEDB.php (which we do sometimes prune) to the latest version. We don’t test all permutations, and so I am sure there are some that don’t work, but generally a jump over the last 2 or 3 versions should. Always worth testing a particular combination before running in production though! Ross
