I upgraded four machines to 1809 back before the release was paused. Three are still running 1809 (now update to 17763.134) without any problems. but on the one machine I use for Hyper-V virtual machines I had an obscure networking issue (which I reported on 8th. October) so imaged it back to 1803. I have just tried upgrading with the re-released ISO and it still has the same issue.
That was a networking problem in its Hyper-V WiFi network switch. While the host machine worked perfectly on the Internet and with two-way communication with the VMs, the host machine couldn't write to shares on other physical machines on the network (but it could read from them perfectly). With Hyper-V removed it had no problems though.
I would recommend to create an image backup first to be extra safe thoughFor now, that one machine has been re-imaged back to 1803 (again) and is staying that way until this issue gets fixed. The others are staying on 1809.
