Decommission one of Exchange in Hybrid infrastructure

Hello,

the organization has two 2010 Exchange servers with the latest updates. I needed to set up hybrid work and do a mailbox migration. Since Exchange 2010 is installed on a legacy Windows 2008 OS, I made the decision to add Windows 2016 with Exchange 2016 to complete the Hybrid Configuration Wizard.

First, I installed the AD Connector and performed a successful sync on one of the domain controllers. In the course of setting up hybrid operation, I chose one from Exchange 2010 that was accessible from the external network. The setup was successful.

If I decommission Exchange 2016, I won't affect the hybrid configuration in any way. After all, it is configured for Exchange 2010, this old server was chosen in hybrid wizard.
Exchange 2016 was only used as a tool for hybrid setup.

Thank you.

    @Mountain Pond

    Removing one Exchange server from the existing organization will not affect the other server. Only uninstalling all Exchange on-premises will affect the use of hybrid. So, you don't need to worry about it.

    You could have a look at the Scenario two.

    It is suggested (not necessary) to rerun HCW after uninstall Exchange 2016.
