WLC 5508 and 5760 Compatibility

[glmharled]

Hi, 

We have 5508 WLC and adding a new 5760..

is it possible for this 2 to be in the N+1 model?

If the 5508 WLC goest down, does the AP previously associated to 5508 need to re-download the image to join 5760?

Or as long as it's running within the following compatibility matrix, The AP wouldn't need to re-download?

Table 4 Software Compatibility Matrix

Cisco 5700 WLC	Catalyst 3850	Catalyst 3650	Cisco 5508 WLC or WiSM2	MSE	ISE	ACS	Cisco PI
03.03.01SE	03.03.01SE	03.03.01SE	7.6 7.5	7.5	1.2	5.2, 5.3	2.0
03.03.00SE	03.03.00SE	03.03.00SE	7.6 7.5	7.5	1.2	5.2, 5.3	2.0

Thanks for all the answers

No, AP will always download the image when they move between 5760 & 5508. Even though they are compatible, AP image is not same in those two platform (Cisco will make this happen in future, but not today).

So it is not a good idea to keep 5760 & 5508 in N+1 setup. Always go with similar platform & firmware versions.

ah i see.. 

but it wouldn't be a problem for them to be in the same mobility domain right?

user should be able to roam between the two?

thanks for the answer

Yes, you can put them in same mobility group.

To do this you have to enable "New Mobility" feature of your 5508 & configure the mobility between each others.

Since 7.5.x is deffered only 7.6.x is the option for this. (7.4.x is not supporting this feature). This will enable CAPWAP inter-controller communication instead of EoIP (used by legacy controllers 5508,2504, WiSM)
