LTM Upgrade

Is it necessary to re-activate license every time you do IOS upgrade? I have two LTM 4200 boxes out of support and i want to upgrade them for testing. They are running on 11.6 and i want to go at 13....

You need to be careful when you upgrade from 11.6 to 13.0 If you are using IAPPS in 11.6 there is a bug that will stop the loading of version 13. I ran into this issue from 12.1 to 13.0

 

here is what the engineer told me BUG ID 666165. The work around to this is removing signatures and checksum from the iApps that had the script dependencies before the upgrade. The workaround is as follow In version 13 modify the tmpl-signature value(tmpl-signature none) and then save. The modifications to the iapps are not necessary. You can use vi to make the necessary changes on the bigip_script.conf(/config/bigip_script.conf).
