cannot remove WIFI6 AP when migrate to WIFI7 AP

When i install all 6 new  unit RAP72PRO, found out that i cannot remove AP720-L

if i remove AP720-L,  most of my SSD will gone missing

question:-
are there separate of cloud setting keep for each AP720-L  and RAP72Pro ?  if yes, how to do i migrate all to RAP72PRo ?
possible what reason ?  eventually we will actually remove all AP720-L  without missing any SSD

(1) There are no separate cloud Settings for each ap720-l and rap72pro
(2) You need to check whether the ap720-l and rap72pro cloud configuration is synchronized
