When performing Windows SBS 2003 to SBS 2008 Migration/Upgrade.
At the stage of:
Run Migration Preparation tool from Windows SBS 2008 DVD
Gives an error of AD in Journal Wrap mode and perform following steps.
The solution is
Delete Event logs from server all logs just delete.
1. Click Start, and then click Run.
2. In the Open box, type cmd and then press ENTER.
3. In the Command box, type net stop ntfrs.
4. Click Start, and then click Run.
5. In the Open box, type regedit and then press ENTER.
6. Locate the following subkey in the registry:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\NtFrs\Parameters\Backup/Restore\Process at Startup
7. In the right pane, double-click BurFlags.
8. In the Edit DWORD Value dialog box, type D2 and then click OK.
9. Quit Registry Editor, and then switch to the Command box.
10. In the Command box, type net start ntfrs.
11. Quit the Command box.
When the FRS service restarts, the following actions occur:
* The value for BurFlags registry key returns to 0.
* Files in the reinitialized FRS folders are moved to a Pre-existing folder.
* An event 13565 is logged to signal that a nonauthoritative restore is started.
* The FRS database is rebuilt.
* The member performs an initial join of the replica set from an upstream partner or from the computer that is specified in the Replica Set Parent registry key if a parent has been specified for SYSVOL replica sets.
* The reinitialized computer runs a full replication of the affected replica sets when the relevant replication schedule begins.
* When the process is complete, an event 13516 is logged to signal that FRS is operational. If the event is not logged, there is a problem with the FRS configuration.
Note: The placement of files in the Pre-existing folder on reinitialized members is a safeguard in FRS designed to prevent accidental data loss. Any files destined for the replica that exist only in the local Pre-existing folder and did not replicate in after the initial replication may then be copied to the appropriate folder. When outbound replication has occurred, delete files in the Pre-existing folder to free up additional drive space.
Also try this too.
Increasing the USN journal size, and thus the number of changes that it can hold before the journal "wraps", decreases the possibility that the USN journal wrap will occur. The USN journal size can be changed by setting the following registry key:
HKLM\System\CCS\Services\NTFRS\Parameters\"Ntfs Journal size in MB" (REG_DWORD)
Valid settings range from 8 to 128 megabytes (MB) with a default of 32 MB. This setting applies to all volumes that are hosting an FRS replica tree. You have to stop and then restart the NTFRS service for the increases to the USN journal size take affect. Decreases to the USN journal size can only be made by reformatting all volumes that contain FRS-replicated content.
The number of changes that a given USN journal file can hold can be estimated with the following formula:
journal size/((60 bytes + (length of file name)) * 2)
