If not then sgn up with new supplier, in your case Voda, give them the PAC, they will do the rest, which includes cancelling EE.

Safer to get the new Vodafone SIM and check all works, signal is good etc (on what will be a temporary number), and then provide the EE PAC to Vodafone.
You can still get the EE PAC in advance.

Otherwise if something bad happens, you could end up with neither working.

Spot on, always check you can get coverage at all of your usual haunts before switching mobile carrier.
