Downgrading Cisco 2504 WLC software from version 8.3.102 down to version 8.2.111

[Mel R]

I have a few questions regarding the downgrading of a Cisco 2504 WLC software from 8.3.102 down to 8.2.111

1. The upgrading WLC software guide says its possible. Is this true? Did anyone try it and had 100% success?
2. Will my configuration on the current release (8.3.102) be intact when I downgrade to 8.2.111?
3. I am doing the downgrade remotely. Is this advisable or should I be on-site when I downgrade?
4. What should I be aware off when I downgrade the software if it is possible to do?

Any help or assistance is greatly appreciated. Thanks.

8.2.130.0 is the code you should downgrade as all other 8.2.x codes are deferred by Cisco

1. The upgrading WLC software guide says its possible.Is this true? Did anyone try it and had 100% success?

Yes it is possible.  

1. Will my configuration on the current release (8.3.102) be intact when I downgrade to 8.2.111?

If you have configured any new features only available in 8.3.x will be lost once you downgrade to 8.2.x  

3.I am doing the downgrade remotely. Is this advisable or should I be on-site when I downgrade?

Always advisable to get a remote console session available during upgrade/downgrade process to see what's going on.
