Changing Equallogic PS6000 Serires IP address

Hello

my equal logic group IP is 192.168.0.1 and my two other storage members are 192.168.0.2 and 192.168.0.3  not management ports  " management ports not configured and cant be now due to both management and iscsi are on the same subnet"

i would like to change the group ip to 172.16.10.2  and my two storage members to 172.16.10.3 172.16.10.4   " i want to get rid of the 192.x subnet in the iscsi storages except management ports." 

if i change the group ip to 172.16.10.2  and enable 1 Ethernet ports on the two members with IP's 172.16.10.3  172.16.10.4  , will that group still be intact and the members can see each other in the group with no issue?  or do i have to reset the storage devices and start all over?

*this is not a production system and there is no data on it yet.*

thank you
