Transfer resources from one program to another

Dear Colleagues,

If I want to transfer all resources with their manhours’ figures from one schedule to another one, knowing that the second schedule is a revision of the first (having same number of activities and activties’Id but links have changed).In P3 it was a simple transfer button but in P3e, you need to make export to a database file then open the second program and make import resources only.

Tell me please what is the best way to transfer all resources with their allocated manhours.

Thanks & Regards,
Jihad Daniel
