Hi @GiantProblems-3647,

Considering that you are still running Windows Server 2008, according to the supportability matrix, you would need Exchange 2016 CU 6 or earlier:

That being said, please also make sure the following co-existence requirements are met before Exchange 2016 is introduced into the existing environment:

  • The Exchange 2010 server has been updated to at least SP3 with Update Rollup 11 installed. It's recommended to install the latest Update Rollup 30 for SP3 and apply the latest security update KB5000978.

  • The Outlook clients are upgraded to Outlook 2010 or above on Windows and Outlook 2011 or higher on the Mac.

For step-by-step guidance to install Exchange 2016 in Exchange 2010 coexistence, here are some articles for your reference:

Please Note: Since the second web site is not hosted by Microsoft, the link may change without notice. Microsoft does not guarantee the accuracy of this information.

Additionally, the Exchange Deployment Assistant tool is highly recommended for the migration. The web-based tool asks you a few questions about your current environment and then generates a custom step-by-step checklist for you to deploy Exchange server. Hopefully you can find it be of help.
