We have Exchange Server 2013 (Build 847.32) at CU4 and was put into production in 8/2014 on a Windows 2012R2 server. It has been working fine since that time but we are considering getting it updated to the latest CU9. It has all Exchange roles.
1. Is it advised to upgrade it even though there are no issues?
2. If so, can we go straight to CU9 from CU4, or do we have to install some other CUs first?
Please advise.
Thank you!
