I recently purchased a new microserver to reduce my power footprint at home. And I had to move the FMC (Firepower Management Center) from the OpenStack deployment that I previously ran at home.

And that it is in fact a journey, but how do you get started on that journey? With your existing network infrastructure? It’s impossible to throw away every piece of equiment and design and start greenfield.
