We currently have all of our foreign AP controllers on software version 7.0.116. This consists of a mixture of 4400 and 5508 WLC's. Our guest anchor is a 4402 on version 7.0.116. We are replacing the guest anchor with a 5508. We are also upgrading our 5508 wireless controllers to version 7.2 to support the 3600 series AP's. My question is what is the recommeded code that the anchor controller should be on? Should it also be upgraded to 7.2? If we upgrade the anchor controller to version 7.2, will this affect anchoring to 4400 series foreign controllers still on7.0.116?
