Steps to update a 4402 WLC from 4.2 to latest 7.x

[zach.mann]

Greetings,

We need to upgrade a 4402 wlc from 4.2 where it is now, to the most recent 7.x release.  I believe this is a 2 step process.  Does anybody know the correct steps to upgrade to?  Obviously we can't just jump straight to 7.x

Thanks in advance!

Looking at the upgrade compatibility matrix for 7.0.116.0, both 4.2 releases show compatibility for a direct 7.0.1160 upgrade.

If anyone knows different, please feel free to chime in.

Thank you for the link!  I did some searching around Cisco's website, and even though I work for a Gold Cisco partner, the support got me nowhere.  Surely somebody on here has done this before and will chime in.

If you read the release notes a little more carefully, you will also see the following:

4.2.130.0 or earlier 4.2 release	Upgrade to 4.2.176.0 before upgrading to 7.0.116.0.
4.2.173.0 or later 4.2 release	You can upgrade directly to 7.0.116.0. Note If you upgrade from 4.2.176.0 to 7.0.116.0, the upgrade fails for the first time. The upgrade completes successfully when you upgrade again.
4.2.209.0 or later 4.2 release	You can upgrade directly to 7.0.116.0.

Just keep the above in mind depending upon your 4.2 release.
