How do I upgrade my F5 from v10.2 to v11.4.1

Hi Danny, the license need to be reactivated to reflect a current service check date.

The service check date must be younger than the software release you try to implement.

The reactivation can be done through WebUI > System > License [Reactivate (manual)] or via CLI using the "get_dossier" utility:

grep -iE 'reg.*key' /config/bigip.license | awk '{print "get_dossier -b", $NF}' | bash -x

The dossier file needs to be posted to https://activate.f5.com/license/dossier.jsp and a new license with updated service check date will be provided.

The license will be imported through WebUI or simply by replacing the current /config/bigip.license.

(Avoid windows line breaks in the license file!)

If you are using command line tools to replace the license, it will be required to run the command "

reloadlic

It´s best practice to create a backup archive as fallback.

If you got a new license installed, you can use the tool "cpcfg" to copy the current configuration including the new license to the target volume (i.e. HD1.2) followed by switchboot and reboot:

cpcfg HD1.2 
switchboot -b HD1.2
reboot
