Hi @SuyPeang-0083 ,

Yes, you can upgrade from CU9 to CU19. Prepare the Active directory with PrepareSchema/PrepareAD.
Upgrade .NET framework to 4.8 which is crucial and Immediately install the Exchange CU19.

Hi @SuyPeang-0083

Like the suggestions provided by AshokM, upgrading from an earlier version before Cumulative Update 13 for Exchange Server 2016, we need to run the /PrepareAD or /PrepareDomain

The Exchange Server prerequisites are list in the official document, prepare the software according to your windows server version.
