Migrate from one Google apps Domain to another

Migrate from one Google apps Domain to another

Hi, due to our organisation splitting, we are looking to transfer one of our Google apps domains next month.

We currently have domain1 as our primary domain in google apps, with Zoho CRM.

We have domain2 as an alias of domain1 in google apps.

We are looking to make domain2 our main domain, by deleting the alias, setting up the new google apps domain and migrating the data across, eventually deleting domain1.

What is going to be the best way to migrate the data for Zoho?

Can we migrate directly from one domain to another, or do we have to de-integrate (if thats a real word!) from one account and integrate to the new one?

Kind Regards

Keith
