Obviously it's a highly controversial upgrade, maybe it's best to not
ever upgrade to it, but Microsoft is already talking about the 1904
upgrade. I haven't been offered this upgrade yet. Microsoft usually
doesn't allow an upgrade between two non-adjacent versions. Just
concerned that I may get stuck on 1803 forever, or I'm going to be
offered the 1809 just weeks before 1904 is offered to me, and I'd have
to go through two major upgrades soon after each other.

I had a similar problem with 1803. It just wouldn't install on my 1709
system. I finally downloaded 1809 from Microsoft's page using their upgrade
tool, and loaded it as an ISO on a thumb drive. I then mounted it to a
software DVD drive, and ran setup.exe from there. No problems and it worked
fine.

You might want to look into some of the issues with 1809. There are some
outstanding bugs that haven't been fixed yet, and if Microsoft determines
that they would affect your system, they won't send you the upgrade. If you
determine that is not the issue, or you want to go ahead and try it anyway,
just use the same method I did.
