How to Resolve a Failed Upgrade Verification for Version 12.0.0.0 Due to a Detached Oracle dSource

During the verification for upgrade to version 12.0.0.0 (from any version 6.0.15.0+), you may encounter a job failure with the following error in the actions panel:

"Verification of version "12.0.0.0" has failed for this Delphix Engine. It is not currently possible to upgrade to this version without Delphix support assistance."

If you click the "Details" link, you will see an error stating "An unexpected error has occurred. Contact Delphix support."

This failure may be a result of a known bug, DLPX-86842 (see Known issues), where if there are any detached or unlinked Oracle dSources, upgrade failure may occur during the 'verify upgrade' job while upgrading to 12.0.0.0. This bug is fixed as of the 13.0.0.0 release.

You can confirm whether you have any detached Oracle dSources by switching to the Management Application and reviewing your configured datasets and looking for the "Detached" status
