After some work to determine the extent of my server problems, I have decided that it is time to go for a complete upgrade. I have another Fedora Linux system that I have been using for several months that is the prime candidate as the target for this move.
Over the next few days I will be moving services such as DHCP and DNS from the old server to the new. After the basic service moves, I will move web and email services to the new server.
I intend to go slowly and ensure that each service is working properly on the new server before working on the next.
There will be outages of various lengths during this process although I am hoping that only one service at a time will be affected. Where possible I will try to post a notification here in advance of outages. I may not be able to do that in all cases but I will try.
Again, thanks for your patience.
