WLC 7.4.100.0 Downgrade

[marco_bartulihe]

Hello,

Some time ago I updated a WLC, model 2504, from version 7.3 to 7.4.100.0. I also update the FUS (Field Upgrade Software) to the latest release, 1.8.0.0.

Now I need to downgrade the WLC back to 7.3 version.

My doubt is: Can I just take the normal processes and downgrade the WLC back to 7.3, even with the FUS in version 1.8.0.0?

Tks guys,

Bartulihe

If you want to downgrade, then I'd recommend that you erase your config.  This is because there are configs from the 7.4 that the 7.3 wouldn't understand.

Under normal circumstances, this should be fine.  But there are some cases that this can cause issues.

Leo,

I do it all the time especially when I beta test. So far I have not had any issues downgrading, but I always double check the config to make sure that the config hasn't changed. Now this could be because of issues I had in the past or when testing beta code, but even when I upgrade, I still check to make sure. There were a few code versions that did change some if my settings back to default.
