Migrating 2010 Resource Calendar to 2013 or Creating New

Hello,

I created a resource booking calendar in SharePoint 2010 using the "Group Worksite" Feature. Unfortunately in 2013 it is deprecated. I have found under content types "Schedule & Reservations" but I can't seem to influence what content goes into that.

I've found the alternative of using overlays, however I need the ability to check double-booking. I found online that I can migrate the old one to the new one and that would allow the previous one to work in 2013, but I haven't been able to find away to migrate it without errors.

Anyone have any links on how to set this up or how to migrate it, or how to create a new one with double-booking features?

Thanks!
