implementing exchange 2019 into the existing infrastructure

Question

Hi!

There is an existing exchange organization with Exchange 2013 and Exchange 2016 servers.

It is necessary to implement new Exchange 2019 servers in the organization for subsequent gradual migration to new servers.

I know the steps to install new servers:

1. Updating the schema
2. AD update
3. Exchange 2019

Are there any problems, moments, tips when implementing this plan? Please share your thoughts, tips, hints, links.

Answer 1

Hello,

 

Thank you for posting in Q&A forum.

When introducing Exchange 2019 servers into an existing Exchange 2013 and Exchange 2016 organization, there are really several aspects to consider to ensure that the migration process goes smoothly. Here are some key steps, considerations, and tips:

1. Schema Update

Prepare Active Directory: Before you install Exchange 2019, you first need to update your Active Directory schema. This can be done using the Setup.exe /PrepareSchema command. Make sure that you back up your Active Directory before performing this step.

Verify the update: After the schema is updated, use the Get-ExchangeServer command to check the schema version to ensure that it has been successfully updated.

2. Update Active Directory

Prepare AD: Use the Setup.exe /PrepareAD command to prepare Active Directory. This will create the required Exchange 2019 related objects.

Permissions: Ensure that the account doing this has sufficient permissions, typically to be a member of the Enterprise Admins and Schema Admins groups.

3. Install Exchange 2019

System requirements: Ensure that the new server meets the system requirements for Exchange 2019, including OS version, memory, CPU, and storage.

Installation process: Run the Exchange 2019 installer and follow the wizard to complete the installation. You can optionally install Exchange management tools and other components.

4. Migration plan

Gradual migration: After the installation on the new server is complete, you can begin the gradual migration of mailboxes and services. We recommend that you migrate a small number of mailboxes for testing to make sure everything is working properly.

5. Precautions

Compatibility: Ensure that Exchange 2019 is compatible with existing versions of Exchange 2013 and 2016. Microsoft provides detailed compatibility documentation.

SSL certificate: Configure an SSL certificate on the new server to ensure secure communication. You can use an existing certificate or request a new one.

DNS records: Update DNS records to point to the new server, ensuring that users have access to the new mailbox.

6. Tips and Advice

Backup: Make sure to back up your existing Exchange environment and Active Directory before making any changes.

Monitoring: During the migration process, monitor the performance and logs of your Exchange servers so that issues can be identified and resolved in a timely manner.

Documentation: Document each step and configuration for future reference and troubleshooting.
