I upgraded Oct 19, 2017, and have been insatisfied since. Your Gen 4 tokens don't carry over unless you invest a few of calls and can get Hughes to relent and convert part over to Gen5. Second, the speed, in both terms of actual & consistency, are terrible, over 80% of the time slower than Gen4. Plan to spend countless hours on the phone getting pushed up to another level & "engineers" but resulting to no lasting consisten sppeds within 60% of the promised "up-to 25). most will be 3 or less, many times 0.5, even after replacing modem & the receiver thing-a-macmachigy" on the dish. It's like being promised freeway speeds but only getting congested stoplight in-city speeds.
Don't convert unless they have completely shut you down. If that is the case, sorry, and there is no real alternative.
