Introduction

This knowledge base article will explain migration path from Hosted Exchange 2007 to Hosted Exchange 2016.

DNS Records

Case A: Customer's domain is hosted by interworks.cloud

In case the domain is hosted on interworks.cloud, the operation team will change the ΜΧ records to point on new Hosted Exchange 2016 mail server. After this change occurs all new email communications will be handled by the Exchange 2016 Server.

Case B: Customer's domain is not hosted by interworks.cloud

If the domain is not hosted by interworks.cloud, the customer is responsible to make the following necessary ΜΧ records changes:

MX Records

mx.spamexperts.com (priority 10)
fallbackmx.spamexperts.eu (priority 20)
lastmx.spamexperts.net (priority 30)

Autodiscover Record

In addition to changing your MX Records, customer will also need to create one of the following DNS records (required due to the AutoDiscover feature in Outlook 2010-2013-2016):

A record for autodiscover.customerdomain.prefix (thus: autodiscover.mydomain.gr) pointing to 188.164.200.89

Or

CNAME record for autodiscover.customerdomain.prefix (thus: autodiscover.mydomain.gr) pointing to autodiscoverredirect.interworkscloud.net

SPF Record

Finally, customer will need to create a new TXT entry (or modify an existing one) in order to configure SPF, as follows:

customerdomain.prefix(thus: mydomain.gr) TXT v=spf1 mx a include:spf.interworks.cloud -all

Having done changing the domain's DNS records, the clients configuration should be followed.

Client Configuration

The Professional mailbox users need to place their email and password during the profile creation. For more details check:

The POP/IMAP users need to adjust their clients following the manual configuration process. For more details check: Add a POP or IMAP Email Account to Outlook

During the Migration: New Incoming/Outgoing Emails

During the migration process all incoming or outgoing emails will be handled by Hosted Exchange 2016. Explaining this statement :

New emails could be received or be sent via the previously configured clients
And \ Or
New emails could be received or be sent via the Outlook Web App of Hosted Exchange 2016 https://mail.interworkscloud.net/OWA

During the Migration: Old Emails

When the migration process starts, the old emails will be accessible only via the Outlook Web App of Hosted Exchange 2007 https://mail.webserve.gr/owa/

Old emails will eventually pop on new email account

As the migration proceeds, the old emails from Hosted Exchange 2007 will gradually appear on the new user mailbox.
