Before you can migrate Microsoft® Exchange data to Google Apps, you need to make the following configurations in the Google Apps control panel:
Set the Email Migration API (EMAPI) option in the control panel
Enable OAuth client access so the utility can access the user accounts in Google Apps
For more information about configuring Google Apps, see “Configure Google Apps” on page 19.
Google Apps Migration for Microsoft® Exchange requires one administrative account on your Microsoft® Exchange Server that has read/write permission for each user’s mailbox. The Microsoft® Exchange permission Receive As is sufficient for this task. For other mail servers, see your mail server administration documentation.
For IMAP migration, you don’t need an administrator’s account or password. Instead, you will need to provide the individual username and password for each user being migrated.

Provision users in Google Apps

Avoid Calendar issues
To ensure that migrated calendar data will be associated with the correct Google Apps accounts, make sure you provision all your users in Google Apps before you migrate any accounts—even if you want to perform only a partial migration. Otherwise, the following issue might occur:
