I need to instal Exchange July security updateshttps://techcommunity.microsoft.com/t5/exchange-team-blog/released-july-2021-exchange-server-security-updates/ba-p/2523421?WT.mc_id=M365-MVP-5000284
My current environment:
Exchange 2013 CU 23
Exchange 2016 CU 20
I’m in the middle of migration.
After installing security updates on Exchange servers do I need to extend schema on both Exchange servers?
If so,in what order?
If I understood correctly for Exchange 2013 CU 23 I need navigate(cmdàrun as admin) to C:\Program Files\Microsoft\Exchange Server\V15\Bin and run “Setup.exe /PrepareSchema /IAcceptExchangeServerLicenseTerms”
And for my Exchange 2016 CU 20 I need to download Exchange CU 21(6.6 GB) ,mount it and find setup for CU21 and run run “Setup.exe /PrepareSchema /IAcceptExchangeServerLicenseTerms”
