Migrating from Google Apps Premium to Zoho Business

Migrating from Google Apps Premium to Zoho Business

Hi,

We currently run Google Apps for our domain. We'd like to leave Google completely and move to Zoho Business, but I'm not finding any clear documentation on how to go about that. We can't afford to have any email down time, and we have a bunch of custom labels/filters setup.

When I log into my default email account, there doesn't seem to be any way to pull email via imap from my Google Apps account in order to get everything setup. Am I missing something? Do you have any specific tutorials that walk you through the process?

Thanks
