I have installed new ZCS 7 server on ubuntu 10.04 and i want to migrate my "old" user.
I have some user on ZCS 6.0.10 on ubuntu 8.04 and the others on exchange 2007.
Can you explain me the best pratice to migrate the user.

I think, i can make a full backup on ZCS6.0.10 and import it on ZCS7 ? but the server name are not the same et i want to remove some domain name

There no tools to migrate Zcs to Zcs ? As i can see zcs use imapsync but how it recover the appointement, contact ?

For exchange, it simply i can use the wizard tools to migrate users

I hope, i explain clearly I m sorry for my poor english
