Hi All,
I am planning to migrate our current Exchange server 2016 CU19 (Hybrid Setup with MS365) to Exchange server 2019. Do I still need to install CU11 on the current exchange server 2016? Thank you.

Follow the Migration Assistant to move between versions once everything has been migrated to 2019.
To reduce the current client's effect, install a new Exchange 2019 server on a new network side, then configure all services (including SCP, all VD's URL, Outlook Anywhere, and MAPI over HTTP) and install the certificate.
Hi @Juan Dela Cruz ,
The requirement to upgrade Exchange Hybrid Server 2016 to 2019 is to upgrade Exchange Server 2016 to the latest cumulative updates.
Then setup an Exchange 2019 Server on a new VM or physical server for migration.
Here is a guide on how to upgrade Exchange : How to Upgrade Exchange Hybrid Server 2016 to 2019? (linkedin.com)
Hope this helps!

@Aholic Liang-MSFT can I directly install the Exchange 2016 CU23 or is there an upgrade/update path that I need to follow? Thank you so much for this information. This is very helpful.
Hi， Of course, you can update directly from CU 19 to CU23. CU23 contains all previous cumulative updates.
