On the back of the Hafnium threat I need to install the latest CU to be able to install the out of band patches.
We are hybrid and only use the internal exchange servers (these are on CU20) for management and the email relay for internal systems.
Never done this before.
How should I install CU23?
Do I need to prepare schema or is like any other next next update?
Anything I should be aware of?
Thanks a million guys.
