Eco-structuring

Cyberforming is the process of converting a planet into an environment hospitable to mechanical lifeforms, particularly Cybertronians. It can be performed rapidly through devices capable of converting organic matter to technological matter, such as the Key to Vector Sigma. It can also be performed manually in a much more gradual process, such as that performed by the Cybertronian Empire in the construction of the Hub.

Beast Machines
In the Beast Machines cartoon, the Oracle revealed that even Cybertron itself was not originally technological, but was cyberformed under the direction of the Quintessons.
