Upgrading WLC 2504 on version 8.0.110.0 to new version

carl_townshend — Mon, 05 Jul 2021 17:16:03 GMT

Hi All

We have some 2504 WLC running version 8.0.110.0.

We want to upgrade this to a more recent version, can anyone tell me what version we should go to and if there is a specific migration path we need to follow?

Many thanks

Have you looked at version 8.5.140

All you need to know can be found in the release-notes:

https://www.cisco.com/c/en/us/td/docs/wireless/controller/release/notes/crn85mr4.html

There you see that you should do an interims-upgrade before going to 8.5.

And it is very likely that you also have to upgrade the Field Upgrade Software to version 2.0.0.0:

Hi Carl,

Yes I would go to 8.5.135.

However you would have to upgrade first to 8.2.16 or 8.3.x

When upgrading, you have to consider the following:

1. Check the compatibility matrix for your AP.

2. Check the Client Types and Supported version

3. Read this column as well on Release notes "Upgrading Cisco Wireless Release"

These are good references.

https://www.cisco.com/c/en/us/td/docs/wireless/compatibility/matrix/compatibility-matrix.html#pgfId-459971

https://www.cisco.com/c/en/us/td/docs/wireless/controller/release/notes/crn85mr3.html#upgrade-instructions_85

For Cisco 2504 WLC, Cisco 5508 WLC, and Cisco WiSM2, the Cisco WLC software image is split into two images, the Base Install image and the Supplementary AP Bundle image. Therefore, in order to upgrade, repeat Step 2 through Step 14 to complete the installation of both the Base Install image and the Supplementary AP Bundle image.

Download the Supplementary AP Bundle image only if you are using any of these APs: AP802, AP803, Cisco Aironet 1530 Series AP, Cisco Aironet 1550 Series AP (with 128-MB memory), Cisco Aironet 1570 Series APs, Cisco Aironet 1600 Series APs, or all of these APs.

Cheers,

Raffy
