can't book resource when update to Zdesk 7.0

[sealeung]

After I updated the ZDesktop to 7.0, I can't send the appointment with resource/location.

It will show the error:
The selected resources/location can not be scheduled for the following instances

As my server-end still 6.0. when run zmcontrol -v:
Release 6.0.7_GA_2473.UBUNTU8 UBUNTU8 FOSS edition.

So does it have any solution to fix it. Or only have to update the server-end to 7.0?

zDesktop 7 works with ZCS 7.
