<p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'>The Unity server was pointing to
an invalid DC and GC. We did not know this because generally the customer did
not change the backend AD user for VM-only users when changing the VM box. So,
AD changes were really infrequent—until yesterday. <o:p></o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'>We fixed the GC/DC issue using
the reconnect tool. However, we did not force it to do a full sync. It would
have done one on its own, but we did not give it enough time to complete one.
So, when we rebooted, the changes were lost (unless of course it had already
given up, in which case they were lost anyway). <o:p></o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='color:#1F497D'>So, the rule of thumb would be
to look in the log for Migrate Subscriber Data and make sure you have no
errors. We saw an error -2143027020 (or something like that) repeat a lot during
the process that resulted in the failure. This appears to be the error that got
the ball rolling. <o:p></o:p></span></p>

<p class=MsoNormal>Hello,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>At a customer, they ran Migrate Subscriber Data to migrate
110 Unity 4.0(5) users from VM only to Unified Messaging. The process showed as
having run successfully. However, after exiting the tool and allowing the
Directory Synchronization to finish, messages still were not delivering to the
correct places consistently. We eventually decided to reboot the server in case
there was a MAPI cache issue due to the change of the Information Store for the
user accounts as well.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Upon doing the reboot, 75 of these 110 accounts were deleted
from Unity. The stream files, user, all of it. The AD user still existed as
well as the messages in Exchange (though they had not migrated). Basically, MSD
lied about doing the migration properly. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Unity is 4.0(5), no ESes that I’m aware of. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Has anyone seen this behavior before?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thanks,<o:p></o:p></p>
