I have a Dell PowerEdge Server installed new at the end of August, with Windows 2019 Standard Server v.1809. This is the version that Dell shipped it with in mid August. It is the first Windows 2019 server that I installed at any of my clients. The client using this new 2019 server is a small dental office with about 14 desktops, and a staff of 8 users.
I know that Microsoft has released new Semi-Annual Channel releases for Windows 2019 Server - version 1903 (released in May) and Windows 2019 Server - version 1909 (just released recently).
I have not yet performed an update of a Windows 2019 with one of these two releases. So, I am not sure what to expect, or even, if I should install at all any subsequent updates for the Windows 2019 operating system. I am a little bit worried that by installing these updates, not necessarily right away after Microsoft is releasing them, I could cause issues for my server, lose data, etc.
Does anyone install these updates on top of the original full server installation, and why? Are there any guidelines on whether I should install these major releases, or just forget about them? Any best practices?
Any feedback would be very much appreciated. Thank you for your assistance.
