Hi i got my first WLC 5508 with software 220.127.116.11 and i deployed in site and the branches i have started registring AP's HREAP mode.
And its working fine .
The second WLC came with software 18.104.22.168 so i doubt if i connect this WLC IN one of the site so it will be a issue .
So whats the best practice. is it possible to Downgrade the second WLC to 6.0 version
Downgrade the second WLC to 6.0 version
Yes you can but WHY?
You're question is slightly "incorrect". 7.2.X has slightly more features so do consider the option to upgrade the first WLC from 6.0.X to 22.214.171.124 or even 126.96.36.199 instead.
You better upgrade both WLCs to the latest version. Besides the bug fixes that you get, there are many new features in 7.0 than 6.0. also, 7.2 is having more features than 7.0.
If you want anyway to downgrade, that is possible. But you may lose your configuratoin. so you need to take the precautions and get a backup before the downgrade.
You want to say "Thank you"? Don't. Just rate the useful answers, that is more useful than "Thank you".
As explained above the code 188.8.131.52 has more features than the 184.108.40.206 also on code 220.127.116.11 that is software problem that the wireless clients are not able to get an IP address from the DHCP server if the DHCP server is the WLC.
If you downgrade the code of the WLC from 18.104.22.168 to 22.214.171.124 the configuration may get lost so as advices make sure to make a back up.
