WLC2504 cange the IOS and backup the License

Hello,
I have a question about updating the IOS of the WLC 2504 
and backing up the license files in advance and then importing
them again after the backup to a higher IOS version has worked. I hope someone can help me there. Oh yes, I am a nature German
speaker. Maybe there is someone here who can help me in my native
language :-) I look forward to your help. Best regards

Hello Hans,

You don't need to backup the license if you only plan to upgrade the software.

Even after the software upgrade, license remains in the WLC.

To upgrade WLC you do not require to take a backup of the Licence, until any upgrade steps suggest this.

you can take config backup and if you like you can copy the License to TFTP 

example take a backup :

Note: when you upgrade to the latest version of the code, make you read the release notes, and check the compatibility of the AP matrix.

How to Ask The Cisco Community for Help

Hello,

can you maybe tell me how I get the new IOS on the WLC and how I then
get the WLC to load the new IOS too. Unfortunately, I'm not a CCNA Wireless
and I'm currently just looking for the right instructions. I got an up-to-date
AES file from Cisco TAC. But unfortunately I don't know how to get them
on the WLC.

I would be happy if someone from you could help me.

I look forward to your help.

Best regards

Here is the process to upgrade:
