Hello Guest. We are upgrading the server's XenForo versions. This has to be done in stages.
1.5.18 ---> 1.5.23 ---> 2.0.0 ---> 2.0.12 ---> 2.1.0.
I will likely upgrade each one and leave it for a day or so to see if there's any kinks. When moving from 1.x to 2.x, our add-ons will cease to work. Much of the functionality of said add-ons is now native within XenForo 2.x, so I don't think we'll miss much if anything. IF we are, we can try out new 2.x XF add-ons.
Euros will go to 2021. They let domestic seasons play out. All domestic calendars are pushed back a little as is CL for 2021. If you know now, you can push Euros to start in perhaps even August '21, and again push things back a bit for domestic/European calendar in 21-22. Keep the start of the season really short because Qatar will be in the winter.
The other thing is you will have to eliminate a Nations League season I think if you end up pushing everything back. OR you could just play the Euros over the course of International dates? Maybe the final 8 just one longer FIFA date.
