Mobility Group between 7.0.252 and Denali 16.3

[felcor]

Dear,

I would like to know if is possible to configure cisco mobility group between two controllers with diferents versions like one with WLC Cisco 7.0.252 and another with Cisco Denali 16.3.

Tks !

it will possibly work, but will not be a supported setup.

also look at this thread where Sandeep Choudhary replies

It will work but keep these thing in mind:

When Diff. controllers in the mobility list use different software versions, Layer 2 or Layer 3 clients have limited roaming support. Layer 2 or Layer 3 client roaming is supported only between controllers that use the same version or with controllers that run versions 7.X.X.

If you inadvertently configure a controller with a failover controller that runs a different software release, the access point might take a long time to join the failover controller because the access point starts the discovery process in CAPWAP and then changes to LWAPP discovery.

in addition  look at the compatibility matrix Table 12 Converged Access Solution Compatibility Matrix

that reports WLC v8.1 as minimum in combination with Denali (any version)
