The changes will happen during the next days. We dont know exactly what will move on which day. But we know all transponders in Band D (10.7-10.95) will move from 1N UK Spot to 2E UK Spot, and we know a lot (and very likely all) 1N Europe Beam transponders will move to 2E Europe beam. So lots of things to happen. Entertaining weeks for Sat enthusiasts ;)
