Exchange Server relocation (Internal IP change)

Hello,

We are in process of relocating our Data Center with this move we need to change our internal IP  For Exchange ( CAS,HT,MB and Edge Transport Servers).

Server A

Client Access Role & Hub Transport

Server B

Mail Box Role

Server C

EDge Transport Role

Do I need to change IP's in any sequence or I can just them.

I really appreciate any insight on how to change IP on the Exchange 2010 SP2.

Thanks

RG
