I have an exchange server 2013 box with Version 15.0 (Build 1076.9)
I believe it is CU8 or CU9.
I know that there are many updates..and the last one being CU19.
Since I m not very expert in Exchange and I am kind of afraid about running the CU19. Is there any "risk" with this ?
Kindly advise as I believe I should upgrade !
