# Domain migration

If you need to migrate all your existing email services to Hosterra Email, we strongly encourage you to proceed as follows:

1. [Create](https://hosterra.help/books/mail-hosting/page/create-a-mailbox "Create a mailbox") in Hosterra Email all the mailboxes you have with your previous provider.
2. [Migrate](https://hosterra.help/books/mail-hosting/page/mailbox-migration "Mailbox migration") all old mailboxes to the new ones and let synchronization enabled.
3. [Configure your DNS](https://hosterra.help/books/mail-hosting/page/dns-configuration "DNS configuration") to point to Hosterra Email services.
4. Wait for DNS propagation to complete: your old server will continue to receive some mails until propagation is complete.
5. [Configure client software](https://hosterra.help/books/mail-hosting/chapter/client-configuration "Client configuration") to use Hosterra Email mailboxes.
6. After 24 hours, delete the synchronization tasks created in step 2, as they are no longer required: all your mails now goes through Hosterra Email.

<p class="callout info">By performing the migration operations in this order, you can be sure of not losing any old or new mail during DNS propagation (which can take up to 24 hours).</p>
