I have a Microsoft exchange server 2016 CU4 installed on Windows 2016 standard server.
This Exchange server is a single server with Mailbox role installed. https://www.prajwaldesai.com/step-by-step-guide-to-install-exchange-server-2016/
This has about 35 Mailboxes. Mailboxes databases are connected through iSCSI based disks.
Currently Exchange server is having no issue and working perfectly..
Windows 2016 server on which exchange server is installed is somewhat corrupted in such a way that I cannot install any windows update or latest .NET framework, thus cannot update Exchange server to latest CU20.
Now to secure my exchange server against latest security vulnerability, I have to install latest Exchange 2016 CU20.
Please guide me the required steps to install (Migrate) exchange 2016 CU20 on another windows 2016 or windows 2019 machine.
Should I install Exchange 2016 Cu4 first on another machine & update later or can I install Exchange 2016 CU20 straight.
Should I install the same way as initial installation or will the steps be different than the following?https://newhelptech.wordpress.com/2017/07/27/step-by-step-how-to-installing-exchange-server-2016-in-windows-server-2016/
