I have a pair of 1600 LTM devices. On 10/3/2014 I upgraded the passive device from 11.2 to 11.6 and everything went well. This device now runs in active mode. I wanted to run this device for a few days in production before I upgrade the other device. I followed the instructions in the docs about upgrading active/passive devices. Do I need to update the licensing again when I plan to upgrade the other now device? I assume there is some kind of time frame for this. I read some links about people this while upgrading... doing one device and testing for a week then doing the other device.
appreciate any input. thanks!
Just make sure, that the license of the F5 which you go to upgrade is re-activated recently.
If you're still paying the maintenance bill for them, you can re-activate them, and if it doesn't activate (i've had this once or twice), then call support and they will activate it for you.
I re-activate before any upgrade just to make sure the license is good. Worst thing in the world to get in the middle of it and find out otherwise.
