Synchronization engine has crashed message for WIT only

Feb 19, 2009 at 3:19 PM

I have downloaded the TFS to TFS Migration Tool v1.1.31205.1 Prerelease. Installed it on a server SERVER1 running TFS 2008 Sp1 (I have upgraded this server from TFS 2005 to TFS 2008 and this server hosts both the tier). I have another server SERVER2 on which I have TFS 2008 Sp1 App-Tier. I am trying to migrate one project from SERVER1 to SERVER2. I am able to migrate Version Control data successfully but the tool fails while migrating the WIT with error as "Synchronization engine has crashed ". Any pointers are highly appreciated.

The most common reason that WIT migration fails is that you dont have the correct permissions.  See this post for details 

If thats not the issue, Terry will have to look at the contents of you "TfsToTfsMigrationTool-Trace.txt" file. You can find this file in the directoy that you installed the tool to.

Hello Curtisp,

Thank you for your reply.
I have already confirmed the equired rights as per the post.
Today when I tried migrating WI from one project on SERVER1 to another project on same sever, it works fine. but again, while migratig from Server1 to Server2 it fails with same error as " Synchronization engine has crashed " I have also searched for "TfsToTfsMigrationTool-Trace.txt" under my installation directory in C:\program Files.... but no such file is available there.

Have you checked on Server2 that the same permission requirement being satisfied? That's my first reaction to your crashing scenario. If not, please let me know. I will need to look into your problem closer.

Have you first verifed that your migration service account is in the "target" server's Service Group account? If not, please take a look of Curtis's post. Otherwise, we need the trace for investigation.

yeah i already did that.... but it didn't work....

actually i have different domain and service account in each server... (ex.TFSSERVER1\TFSSERVICE, TFSSERVER2\TFSSERVICE)

so i did Curis's post to each server .. but it did not work..

and i really want to know that i have to use Active Directory Domain Controller?????

how about if i make a work Item with different language for example.

in the manual video, he used Bug and Task

but , we made in our language (korean)

then how can i fix it?

I had this issue and discovered that it was due to deleting the VC migration session before running the WIT migration (and attempting to link them).  I tried again and left the VC migration session.  This time it worked.
