My switchover happened today and so far, touching wood, everything is OK. The change seemed to happen pretty much at midnight as yesterday my Smart Hub webpage says that phone was not configured, but when I checked just after midnight that section had our number in it. This morning I had an email from BT saying "you're good to go" and I can call out and receive calls with no issues.
From start to finish we've only had one glitch. Initially I had an email on 30th August saying we'd be switched over in the next 30 days, and that I'd get an actual date in a later email. A few days later a card came through the door repeating this, and inviting me to order a free digital voice adapter from the EE store (took one, although I'd already ordered two Advanced Phone with Alexa handsets.) After that, silence. 30 days after 30th August came and went with no "go live" date arriving. I posted on here asking for clarification and NeilO - one of the moderators - reached out to me via private message, discovered what the issue was, and kick-started it all. A few days later I got an email saying we'd be switched on 12th October, then another yesterday saying it would happen overnight, and true to their word it's happened.
Haven't had chance to really try the new handsets yet but if anyone else is getting them you can pair them with your hub and leave them on charge before you go live - we've had ours on their stands for about three weeks! - and also create contacts in advance, and they'll sync with the hub when you're switched.
Thanks again to NeilO for his help in fixing the one glitch that happened along the way.
