Can not login dashboard after changing mongo dbpath

hi,
I have one on-premise tyk setup. Since the mongo cost too much disk and I determined to change dbpath to a new location by running “mongod --dbpath /new/path”, and after that i can not login dashboard any more and response with “Credentials are incorrect, please try again”. BTW, the mongod runs well after switch dbpath.
I tried switch back to original dbpath and restart mongod & tyk-dashboard and no luck.
How can i find out or reset the user information without subotaging current APIs and Keys?

Hello!

Information about dashboard users stored in tyk_analytics_users, ensure that it was properly copied to the new location.
