Infinity install this week - things to know?

I'm due to migrate from Sky copper to Infinity this week.

The Home Hub has arrived, anything I should be aware of or just wait until the day and connect the box?

I did wonder if it makes a jot of difference when the old box is disconnected and the new box connected?

You wouldn't be able to use Sky with the HH5 so if you swap before the change over you will have no Internet until the changeover happens.

Personally I would wait until the Sky connection goes down and then swap to the HH5.
