Overview of Migrating to ZCS > Identify the Domain Strategy

Identify the Domain Strategy
When migrating from Exchange to ZCS, you select which domain the users’ accounts migrate to. Make sure the destination domain is created in ZCS before you migrate your data.
The migration process contains a few considerations regarding naming:
*
Only data from a single domain can be imported. For example, you might migrate users from marketing.domain.com on your Exchange server to marketing.example.domain.com on your ZCS server.
*
The local part of the user’s SMTP address in Exchange becomes the first portion of the email address on the ZCS server. For example, if migrating from an Exchange domain marketing.domain.com to ZCS domain example.marketing.domain.com, the joe@marketing.domain.com would become joe@example.marketing.domain.com in ZCS.
*
If your users use the Calendar application, and you are employing the phased migration method (you are not migrating all users to ZCS at the same time), configure ZCS with the same domain name as used on the Exchange server. When ZCS is configured with the same domain name, a user's existing email address will be retained when the account migrates to ZCS.
*
If user email addresses are changed when you migrate (for example, from "joe@marketing.domain.com" to "joe@example.marketing.domain.com"), users no longer receive meeting updates on existing meetings because appointments and meetings requests contain organizer and recipient information in the form of email addresses.
