When attempting to migrate a user account into the destination domain the following error is displayed:
<userpath> user LDAP error 0x44. Already Exists (00002071: UpdErr: DSID-031B0B59,
problem 6005 (ENTRY_EXISTS), data 0
This is due to an Active Directory limitation. User accounts that have the same display name cannot exist within the same OU.
The accounts can be modified during the migration by using an import file, or simply move them to a different target OU during creation.
For more information regarding the usage of import files please refer to the links below:
