Roaming between 4400 and 5500 controllers

[fvaldivia]

Hi, we are planning to do an AP migration, but there is a doubt for this.

Actually we have a 4402 controller with 1120 APs both of which are marked as EoL products, we want to jump over the new 2600 APs and 5508 Controller for increase signal coverage but we have the following deals:

Last firmware for 4402 controller is 7.0

Firmware needed for 5508 to support 2600 APs is 7.3

Is it possible to configure mobility between 4402 and 5508 even with different firmware branch?

Personally,

If the locations are connected and you can roam between 2 controllers on different codes, you dont want to do that.

If you are looking for anchoring, yes its supported.

Inter-Release Controller Mobility (IRCM)

Table 10 lists the inter-release Controller Mobility (IRCM) compatibility matrix.

Table 10     Inter-Release Controller Mobility Compatibility Matrix

CUWN Service	4.2.x.x	5.0.x.x	5.1.x.x	6.0.x.x	7.0.x.x	7.2.x.x	7.3.x.x
Layer 2 and Layer 3 Roaming	X	-	-	X	X	X	X
Guest Access/Termination	X	X	X	X	X	X	X
Rogue Detection	X	-	-	X	X	X	X

¹ In the 7.2.x.x release, RF Groups and Profiles were introduced. RRM for 7.2.x.x and later releases is not compatible with RRM for any previous release.

It is highly recommended to Test Mobility(L2, L3 roaming) before implementing between 7.0.x.x and 7.3, Same for auto-anchor.
