When running nwsetup-tui on Node 0, it errors out in monogrestore command for admin collection. "Cannot restore users of auth version 1 to a server of auth version 5" See attached screen shot. Image description
NW 11 mongo db is incompatible in authentication version vs. 10.6.x mongo db.
By default, the 10.6.x mongo admin collection does not contain any user, so we can skip admin collection restoring. Use below steps to workaround this issue.
