When running the Move-CsUser and Move-CsLegacyUser cmdlets, you may experience a failure due to user information between Active Directory Domain Services (AD DS) and the Lync Server 2010 databases being out of sync because the initial replication is incomplete. The time it takes for the successful completion of the Lync Server 2010 User Replicator service's initial synchronization depends on the number of domain controllers that are hosted in the Active Directory forest that hosts the Lync Server 2010 pool. The Lync Server 2010 User Replicator service initial synchronization process occurs when the Lync Server 2010 Front End Server is started for the first time. After that, the synchronization is then based on the User Replicator interval. Complete the following steps to verify user replication has completed before running the Move-CsUser and Move-CsLegacyUser cmdlets.

To verify user replication has completed

  1. Log on to the computer where Topology Builder is installed as a member of the Domain Admins group and the RTCUniversalServerAdmins group.

  2. Click the Start menu, and then click Run.

  3. Enter eventvwr.exe and then click OK.

  4. In Event Viewer, click Applications and Services logs to expand it, and then select Lync Server.

  5. In the Actions pane click Filter Current Log.

  6. From the Event sources list, click LS User Replicator.

  7. In <All Event IDs> enter 30024 and then click OK.

  8. In the filtered events list, on the General tab, look for an entry that states user replication has completed successfully.
