AFAIK all mains interlinked alarms use 3 core and earth so it would
just be a case of wiring in the new bases as per their instructions.

You may even find if they have a standardised base, you can just swap
the alarms and leave the old bases.

I did this and even replaced an ionization alarm with an optical one
to reduce false alarms.
