Users wont login after chnaging mikrotik os

I’ve changed my Mikrotik OS from one server to another one(5.0rc3 to 5.14)
I’ve done back up usermanger with “tool user-manager database save name=123” and restored with “tool user-manager database load name=123”. all of my settings and users all resetored, but some of my users can not connect (some of them can successfully). all of my profiles work fine with new users but the old ones are not working any more.
What should I do…
