Thanks for your response, actually we have WLC 2504 running software version 220.127.116.11 and we have 50 APs AIR-CAP3602e-x-K9. Now we want to add 25 more APs but this time we are going with 3700 series APs. For 3700 we should have software version 7.6.130 or 8.0. whether it will effect our current environment and what type of issue we can face...? we are also looking for HA solution i want to know how it will work? Our service contract with cisco has already expire.. we have to renew that as well to upgrade and ait-ct2504-HA-K9 for HA of controller. and for license which option i have to choose L-LIC-CT2504-UGP ?? whether its mandatory to license upgrade??
