Hi, 
I did this resently, its very simple and worked for me even on my BEST licensed BIG-IP's.

The one thing of warning just to be prepared for is that i found some of my older BIG-IP that were installed from older 14.1.x images wanted to have the license file reuploaded or in my case reset by support (i don't keep the license files) before they took the config and allowed me to rebuild the cluster.

Something i'm glad i knew before i hit my production deployments! As our place gets really ratty when you have a degraded cluster whlist sorting.

    Hello,

    thank for the information dear, i will reactivate the liscene before upgrade.

    same is the case here our place even gets more ratty when you have degradation.
