reactivate F5 BIG-IP VE with expired license.............

You need to get a new eval. licence for VE.

@f5_rock. Yes, but how do you apply this license key after expiration. When you are connect to the admin page, and within the License section (the only one available). In the re-activation section, under general properties, you have the old Base registration key. There is now way to apply a new base registration key if you happen to have a 2nd eval key. It could also be my problem that my second un-used val key also only has a 45 day trial and is expired even though it was never used.

When I have had to re-license expired VEs I used the CLI method as you're able to specify a new base key when requesting the dossier if the Web UI method is grayed out or the WebUI is inaccessible.
