In previous versions of Directory Server, user activities were controlled by assigning each user to one of four possible permission levels. These were: Modify, Add/Delete, Administrator, Schema Administrator.
When you upgrade to 5.0 or later, your Directory Server user accounts are automatically migrated to the new groups and permissions model. Each user is assigned to a default group possessing permissions equivalent to its permission level.
| Permission level | Equivalent Group |
| Modify | Modify |
| Add/Delete | Add/Delete |
| Administrator | General Administrator |
| Schema Administrator | Directory Administrator |
Consequently, your users should continue to have the ability to access and use Enterprise Server Administration in the same way as before.
In previous releases, user information was stored in the CCIUSERS.dat file. It is possible, using the Import Users function of Enterprise Server Administration, to manually import users from the CCIUSERS.dat file of another Micro Focus Directory Server installation running on the previous version. To do this, you must be running your Directory Server in unrestricted mode.
