Hi @oner1,
Welcome back to our Community Forums and thanks for your post 🙂
I have checked our systems and the switch over will be done remotely so it shouldn't make a difference if you connect the adapter just before you leave ready for migration or on return.
If you do have any issues, feel free to give us a shout and we will be more than happy to help and if needed get a technician out.
Have a lovely trip!
