Let us learn it further.

How to prepare for the Exchange 2019 migration?

Some crucial pre-installations for the Exchange Server 2019 migration are –

  • .Net Framework 4.8 Setup on source server
  • Microsoft Unified Communications API 4.0
  • Microsoft Visual C++

It is quite important to know some information and aspects if you are going for the Exchange 2019 migration. Let us read about it.

No more Unified Messaging

The latest Exchange 2019 version has eliminated the feature of Unified Messaging completely. Users will not be able to continue with this service in this new version. The users should need to pay attention if they currently have the UM-enabled mailboxes in their current version. If they are going to migrate or export these UM-enabled mailboxes to the new Exchange 2019, there is high possibility to lose the beneficial voicemail feature and other related facilities after the migration.

We suggest the users with UM-enabled mailboxes in their current version to perform these mailboxes migration by setting up a hybrid to access to cloud voicemail or migration to Skype for Business Server 2019 via professional third-party voice mail software.

Unsupported Exchange 2010 Co-Existence

If you are currently using the Exchange 2010 version for your organization and seeking a migration to the latest Exchange 2019 version, then we must tell you it is not possible directly. In fact, the co-existence of Exchange 2010 and Exchange 2019 is not compatible on the same system. The manual solution does not support one way migration from Exchange 2010 to Exchange 2019 due to this confliction.

The only option here for the users is to first upgrade their current Exchange 2010 version to either Exchange 2013 or Exchange 2016. After the upgrade or migration, decommission the Exchange 2010 completely and then follow the migration from Exchange 2013 Server to Exchange 2019 Server using the native method.

Note: Exchange Server 2013 (with CU21 update or later) and Exchange Server 2016 (with CU11 update or later) can co-exist with Exchange Server 2019.

No Free Hybrid License

Unlike previous Exchange Server versions, the latest Exchange 2019 version does not get or support the free hybrid license for the hybrid deployment of the other Exchange Server versions. In fact, this Hybrid License is a requirement for the older Exchange Server versions – Exchange 2010 and Exchange 2007. For the current most popular Exchange 2013 and 2016 versions, hybrid deployment is possible even without the license.

If you want to have the hybrid deployment and still want the migration to the latest Exchange Server version, then consider migrating to the Exchange Server 2016 version.

Windows Server Upgrade

The Exchange Server 2019 version supports only Windows Server 2012 R2, 2016 2019 (Standard or Enterprise version) and does not work on other Windows Server versions.

One who is seeking the migration to the Exchange 2019 version must be aware of the need to upgrade his Windows Server version to 2019 and then start the migration preparations.

Note: To run the Exchange Server 2019, the supported network provider is IPV6 as otherwise Exchange could not be run.

Supported Email Client

As it is mentioned earlier also, the mailboxes migration is feasible from either Exchange 2013 or Exchange 2016 to Exchange 2019 only using the native migration method, you need to think about the email client as well along with the Exchange Server upgrade from the Exchange 2010 version. The latest Exchange 2019 version does not shows compatibility with the Microsoft Outlook 2010 version.

Users are suggested to install minimum the Microsoft Outlook 2013 version along with the upgrade from Microsoft Exchange 2010 version to follow the final migration to the Exchange 2019 version.

Now that we have studied the most crucial aspects which needs to be followed before starting the migration to the Exchange 2019 version, users are expected to follow them strictly to get a pain-free Exchange 2019 version.
