Changing hub and passwords

[Irish12345]

Hi. 
I have been sent a new Sky hub which I haven't had the courage to set up yet. Rather naively I didn't realise passwords and hub name would change. Also my present hub ends in 2.5 as Sky spent ages sorting it out. The new one doesn't end in this. Is it easy to change all passwords etc on all my Alexa and bulbs and plugs etc? Sorry long message. As I say not attempted it yet as I feel I will need several hours to get it working. I find Sky are not good at helping because I can never get in touch. 
m thanks everyone

Hi @Irish12345 

You can follow the guide below if you wish to split your WiFi bands

You can also just change the name & password of your new hub to the same as the old one so all your devices will just reconnect.
