Hi All, 
I've currently got an Orcon ADSL2 plan which back in the day was "Genius Go" aka 200Gb data, plus calling with standard extras voicemail and call waiting.

Im in a position where i want to change to the unlimited plan, still on adsl2

1) Will I expect any downtime? 
2) Whats going to change? in the modify plan web app in the orcon portal, it doesn't seem to know about my phone extras, and wants to change me more.
