Migration – Email Service Provider – 3

Google provides an Administration Guide for email migrations to Google Apps. Google has done a great job of documenting the migration process and even provides a Google Apps Migration for Microsoft® Exchange tool as well as video documentation.

You download this tool, provide a user list, and the tool will authenticate to your existing email server and migrate the email to Google Apps platform.

The format for the user list is as follows:

user1#user1password, google_user1

For example, if you had a user with the email address of [email protected] and a password of “letmein” then your user list would be:

[email protected]#letmein, migration


Migration – Email Service Provider – 2

If you are ever completing an email service provider migration (to Google Apps) you may use the Google Apps Migration for Microsoft Outlook® tool provided by Google for users who have POP accounts.

To use the tool you sign in with the credentials for the email user, locate the .pst file(s) to be migrate and the migration tool does the rest.

Additionally, the tool creates a log file in Windows 7 in the C:\Users\%username%\AppData\Local\Google\Google Apps Migration\Tracing\ClientMigration directory.

Migration – Email Service Provider – 1

Currently, I am assisting with the technical planning for an email service provider migration for my employer. One of the things to take into consideration for this type of project is reducing the impact of any possible down time with email.

One of the ways to reduce any impact is to perform such a project over a weekend (when normal business is not taking place). Additionally, you may considering changing the default time-to-live (TTL) for the MX records. In our case, the default TTL is set to 86400 (1 day) so we are changing it to 7200 (2 hours). This will make sure that when we change the MX records for our domain all of the DNS servers around the globe will receive that change within (2) hours. Therefore, theoretically, any new incoming email while be forwarded to the correct mail servers within (2) hours of the MX record changes.

As always, with any changes made to your existing infrastructure always plan carefully and document the changes (i.e. change management or change tracking).
