I need to Upgrade my NCS to version 220.127.116.11. Actually my NCS is in the version 18.104.22.168 and i have a lot of templates configured and 1500 Access Points applied.
I have 5 WLCs and will do too the upgrade in the WLCs to version 22.214.171.124.
Will I lose some configuration with these upgrades ? Because the version 126.96.36.199 has more features than version 188.8.131.52 in the NCS and the WLC was adjusted some bugs.
The configurations that i has in the NCS version 184.108.40.206 is H-REAP and in the version 220.127.116.11 will be the FlexConnect, theoretically is the same, but i don't know if the configuration is the same in the two versions.
Will i have some problem with these upgrades ?
Can i do a downgrade in the NCS from version 18.104.22.168 to 22.214.171.124 if i have problems ? I was looking for a document who show how can i do this, but i didn't find nothing about.
Upgrade an downgrading is very much the same. When you upgrade, you shouldn't loose anything, if you downgrade you might, depending if you have a feature in the newer version that isn't supported in the older version. Take a look at the release notes for specifics on upgrading to the 1.1.058 version, they will have everything in there for you to perform the upgrade.
