in our company we have 2 exchange servers, but these servers are not updated properly . now i have to install updates, but most of the articles saying i have test updates before installing, but i dont know how to test.
do i have to take the backup of existing server and restore it on test machine, but the server backup is around 1TB.
it may be a silly question but i never done it before. please help me how to set up test machine and testing update. while testing updates what should i consider.
can i install security updates without testing ?
