I am carrying out a dry-run of an imminent TFS 2010 migration upgrade to TFS 2013.5 on a dedicated Windows Server 2012 R2 Datacenter host, following the steps in [this YouTube tutorial] (https://www.youtube.com/watch?v=nm-WOLc-GQQ) by Mohamed Radwan.
The intention is to keep the newly-implemented TFS 2013 running simultaneously with the TFS 2010 instance for a few days while we validate the migration upgrade. Once satisfied all's gone well, we'll then complete a full switch to the TFS 2013 instance and decommission the TFS 2010 instance which is implemented on a Windows Server 2008 R2 Enterprise.
The tutorial recommends using the TFSConfig Backup and Restore utilities to backup the existing TFS 2010 databases and reporting services key and then restoring them to my SQL Server 2014 instance on the TFS 2013 host.
Following the database and reporting key restore which has also completed successfully, I sought to adhere to the TFS cloning recommendation advised by various sources including Microsoft Support, by running in the following order, these TFSConfig commands:
- TFSConfig PrepareClone
- TFSConfig ChangeServerID
- TFSConfig RemapDB
Problem is, when I attempt running the PrepareClone command, I keep getting the TF30040 error message (as per this thread's subject title). On the few times that I've proceeded regardless and run the ChangeServerID and RemapDB commands however, they complete successfully.
I desperately need some help resolving this TF30040 error, as all attempts to apply some of the resolution steps proposed in other related incidents have failed miserably. It's important I find a resolution due to the fact we're intending to run the two instances for a few days while verifying and validating the TFS 2013 upgrade.
Another key question I have is whether it is mandatory that I successfully execute the TFS PrepareClone command, despite the fact I'm successful executing the ServerID and RemapDB commands? In other words, is it safe to ignore the PrepareClone failure and proceed with the simultaneous running of both TFS 2010 and TFS 2013 instances for those 2-3 days of validation testing?

If you don't run PrepareClone command, the original resources will be used by both the original and the new servers. If both the original and the new servers are live and point to the same SharePoint or reporting resources for any amount of time, you could end up with corrupted databases.
You may keep one server live at the same time. Or try to use a new service account that has no access to production environment to run the command:
TFSConfig PrepareClone /SQLInstance:ServerName /DatabaseName:DatabaseName /notificationURL: ApplicationTierURL
