Use Miration Tool for Zimbra 6.0.x Slave to Zimbra 8 Standalone Master

Hi!

Actual Configuration
Zimbra 6.0.x

Zimbra 1 / Europe Master --> VPN --> Zimbra 2 / China Slave

On Zimbra 1 all Mailboxes are stored for domain @abc.com on, on Zimbra 2 all Mailboxes are stored for domain @xyz.com

Now we have a lot of Problems with the VPN to China, and we don't really need the Master/Slave Configuration.
So we will remove the VPN und use every Zimbra Server as Standalone for thier Domain.

So is it possible with your Migration Tool to migrate the Domain on Zimbra 2 (@xyz.com) to an new Zimbra 8 Standalone Server?
I think to remove the Slave Server on Zimbra 1 should not be a problem.

Thank's for your answers!
