Ah, crap... We added 2 newoperational attributes (nbChildren, nbSubordinates, that contains the number of direct children and the number of subordiante). Those AT will be missing and you'll get a NPE when starting M23 with the M21 schema... The server should work with your data, but with M23 schema. One option would be to install M23, and just copy your partition data.
