@Darcy10 Are you just doing a Fibre upgrade from an existing sky service? The theory is yes the copper connection stay's up, the Engineer's do all the needfull to get the Fibre installed, they test and update the ONT FW and make sure it's all ok on that side, this assumes that they know what they are doing, then the awkward part we need to change over your hub from the copper to the fibre and you hope it all goes smooth, no glitches and no messing about, it's a five minute change Fibre is up, copper is on it's way out, you cannot have BOTH at the same time....
If you wish to play safe and do the cannot change it over now as i am working, then as soon as the Engineers walk away it is going to be all down to you. Hope that answer's all the potentials...
