We are on GroupWise 2014 R2 running on SLES 11

One of our users received a new smartphone to upgrade an existing one. The old phone was sent a wipe command from the MDM server and it would appear that a sync with the datasync mail server had commenced deleting all the contacts.

Now the user has a nice new phone with no contacts.

Any ideas how to restore the contacts for just this user? we have a good full backup from 4 days ago which will do.
