Google Apps Migration for Microsoft

®

Exchange relies on a list of users so that it knows

whose data to migrate. For each group of users you want to migrate, you need to provide a
CSV file of user names. If you plan to use multiple client machines, you need a separate list for
each client, and each list must contain a unique set of users. We recommend each list contain
500-1000 users.

Important:

Check the format of the CSV file you are using before you begin migration. If your

CSV file includes unexpected formatting (such as an extra comma at the end of the record),
this may cause errors during migration.

Microsoft® Exchange Server

Identify users by their primary email addresses, as in the following examples.

If the addresses in your mail server and Google Apps are the same, you need only one
address per line.

[email protected]

[email protected]

[email protected]

If the addresses in your mail server are different from the addresses in Google Apps, then you
need two addresses per line: the mail-server address followed by the Google Apps address.

[email protected], [email protected]

[email protected], [email protected]

[email protected], google_apps_user [email protected]

IMAP Servers

When you migrate from an IMAP server other than Microsoft

®

Exchange, you need to identify

users by their IMAP user IDs and passwords, and by their Google Apps user names:

userid1#user1password, google_apps_user1

userid2#user2password, google_apps_user2

userid3#user3password, google_apps_user 3

where

userid

can be a user’s email address, user name, or other identifier. Exact

implementation varies by IMAP server. For most servers, the

userid

is the user’s email

address. For Dovecot and Courier IMAP servers, the

userid

is the user name.
