Hi All,

I am not sure on the exact version but it is from this year X60 AX5400.

I bought the triple pack from Amazon in February this year. All has been perfect until today. 

One of the units (not the main one and on a wireless backhaul) just stopped having power. I tried it in another socket etc. but no luck. 

I went to Amazon customer service and they are sending me replacements out (today!) And in advance I just wanted to see the best way to switch them all over (they of course want all 3 returned not just the faulty one)

What's going to be the easiest way to switch them? (Start from scratch Vs one at a time Vs add new and then remove old)

Bearing in mind I will receive the new ones before I must return the old ones!

The main deco is connected to virgin router in modem mode and the other is connected via ethernet cable. (and have no issues currently!)
