Office 365, Hybrid, On-Prem CU Upgrade.Exchange 2016.
Hi Robert,
Since you do not have nothing pointing to Exchange, you can do the upgrade without any downtime.
See the upgrade paths in the below requirements.
If you're upgrading to Exchange 2016 CU4 from Exchange 2016 RTM, CU1, or CU2, is recommended that you install Exchange 2016 CU4 before .NET Framework 4.6.2 or .NET Framework 4.6.1 and its related post-release fixes.
After this install Exchange 2016 CU8 and then .NET Framework 4.7.1
Please see the requirements https://technet.microsoft.com/library/bb691354(v=exchg.160).aspx and here also https://technet.microsoft.com/library/aa996719(v=exchg.160).aspx.
HelloNunoAriasSilva
In regards to CU installation, is this standard process to ist install on Hybrid server. Because some articles are suggesting we can do it vica-versa, on On-prem and followed by hybrid.
Can you please help me with any microsoft article . thanks
Hi Avinash1991,
Always the front-end servers first.
