I have two 8510 wireless controllers running in SSO mode and I would like to upgrade from 7.4 code to 7.5 to take advantage of the AC modules that I have in our 3600 access points. What is the prescribed method of doing so on the 8510's?

You can upgrade or downgrade the controller software only between certain releases. In some instances, you must first install an intermediate release prior to upgrading to software release 7.5.102.0.
shows the upgrade path that you must follow before downloading software release 7.5.102.0.
Upgrade Path to Controller Software Release 7.5.102.0 | |
Current Software Release | Upgrade Path to 7.5.102.0 Software |
7.0.x releases | You can upgrade directly to 7.5.102.0 Note If you have VLAN support and VLAN mappings defined on H-REAP access points and are currently using a 7.0.x controller software release that is prior to 7.0.240.0, we recommend that you upgrade to the 7.0.240.0 release and then upgrade to 7.5.102.0 to avoid losing those VLAN settings. |
7.1.91.0 | You can upgrade directly to 7.5.102.0 |
7.2.x releases | You can upgrade directly to 7.5.102.0 Note If you have an 802.11u HotSpot configuration on the WLANs, we recommend that you first upgrade to the 7.3.101.0 controller software release and then upgrade to the 7.5.102.0 controller software release. You must downgrade from the 7.5.102.0 controller software release to a 7.2.x controller software release if you have an 802.11u HotSpot configuration on the WLANs that is not supported. |
7.3.x releases | You can upgrade directly to 7.5.102.0 |
7.4.x releases | You can upgrade directly to 7.5.102.0 |
