Pretty sure in Tesco's case switching to openstack is a decade long project.

I think they can do it in 5 years with some investment. Which is how long they need Broadcom to honor the current contract. The effort is mostly technical, and much of it you can just hire contractors to help.

		I would bite the bullet and begin any switch from Broadcom now on the principle you can never trust the vendor again and you will just be kicking the can down the road.
