Hello ,
Just finished to update my test exchange environment from Exchange 2016 CU13 to Exchange 2016 CU14.
Please find some comments :
1. Before the update , I updated from DOT NET 4.7.2 to DOT 4.8 , as it will be mandatory for the CU release December 2019 (see previous announcement)
2. No need to perform any AD schema update when you are updating from CU13 to CU14.
However if you are updating from CU12 to CU14 , then AD schema update is mandatory due to CU13 in the middle which is requiring schema update.
See below the different AD object to verify for each version for the lastest exchange 2016 CU
