Changing SCAN IP, PUBLIC IP and VIP on 2 node 11g Release 2 RAC

We have a 2 node 11g R2 RAC on Windows 2003 X64
we are relocating the servers to different location and hence need to change

1) PUBLIC IPs
2) VIPs
3) SCAN IPs


We would like to know what is the recommended sequence we need to follow to make these changes.
Should we first change the SCAN IP's and then PUBLIC IPs and then PRIVATE IPs? If not, what should be the sequence?

Also, could you please verify the following steps for chaning the Public IP and VIP

1). Backup current ocr file with command: ocrconfig -export $ORA_CRS_HOME/ocr_bak.ocr -s online
2). stop crs using command: crsctl stop crs (run this on all nodes)

Howdy, Stranger!
