Domain Migration Administrator 6.x
Domain Migration Administrator 7.x
During the process of migrating accounts with SIDHistory the API adds the account to the DomianName$$$ local group in the source domain. If for some reason the account is left in the DomainName$$$ group then the RC=1378 error message will appear.
To resolve this issue, remove the account from the DomainName$$$ local group in the source domain and re-migrate the account with the SID history option selected.
