Restoring a snapshot of a Datanow v2 appliance configuration which contains a Wildcard Certificate (eg *.domain.com) may fail to restore successfully on a Datanow v3 base appliance. The configuration will restore successfully onto another Datanow v2 appliance.
This is caused by the certificate issue which is described in this article: Wildcard certificate import fails on DataNow 3.0 appliance
This issue has been resolved by our development team as of DataNow 3.0 Update 1. This patch should be installed prior to restoring the v2 appliance configuration.
