Receive a 'Downgrade is denied' error when migrating from YouTrack cloud to a local instance of YouTrack using the latest download

I'm experiencing  what seems like an unsolvable problem.

The current YouTrack cloud version number is 5.0 (build #7223) and the current version for the YouTrack standalone download is 5.0 (build #7220).

Because of this, I get the following error when trying to migrate the cloud database to the local:

Is there any way I can get around this? The latest version of the Python script appears to be broken with Python 3.3.2, so I cannot use that either.

Hi Morrison,

YouTrack Stand-alone build will be updated this week.
But we can provide you with the latest build right now to let you complete migration successfully. Please, clarify what kind of build do you need: jar, war ?

Thank you.

Hey Andrey,

That'd be awesome. A war would be perfect!

Andrey Tigay, I have the same issue.

Using InCloud YouTrack 5.0.3 (build #7437 [23-Sep-2013 17:16] )
Downloaded the latest Standalone Version: 5.0.3 Build: #7423.

Getting the same error as Morrison.

Also, where do I put the WAR-file?

Customer support provided us with a compatible database from our InCloud instance. Problem solved (for me at least).
