upgrade WLC from 6.0.199.4 to 7.4

[Eric]

Hi all,

I would like to upgrade wlc from 6.0.199.4 to 7.4. I would also like to keep my previous 50 licences.

I read somewhere that i should first upgrade to 7.0 to keep my previous licence (because if I go directly to 7.4 I will lose it).

Could I have a help?

Best regards

Hi Eric,

You should read the release notes before upgrading:

But you will need to upgrade to an intermediate version:

"It is not possible to directly upgrade to the 7.4.100.0 release from a release that is older than 7.0.98.0."

Thanks

Chris
