F5 Journeys Migration Deployment Failure

Hello all,

I'm migrating configurations off a pair of BIG-IP 5050 appliances to new R2800's devices. The 5050's are running code version 15.1.5 and the rseries 15.1.10.3. For some reason, I'm getting the error below when attempting to migrate the UCS file with Journeys:

Deployment stage 'Deploy UCS' failed with the exception: Extracting manifest: /var/tmp/install_all/plaintext.ucs Product : BIG-IP Platform: UCS : C109 System: Z101 Version : UCS : 15.1.5.1 System: 15.1.10.3 Edition : UCS : Point Release 1 System: Point Release 3 Hostname: UCS : old-hostname.mycompany.com System: new-Hostname.mycompany.com The system hostname is changed to old-hostname.mycompany.com Installing --full-- configuration on host old-hostname.mycompany.com Installing configuration...

Any ideas?
