It is just to move the node for an other place to use the abilities from node.
You can use Estate Transference to move the whole thing to a demiplane - that's my usual go-to, and then build the plane up around it, as once you have it' you'll want to expand it.
If you'd rather not move any of them, there is a spell (and power) called Node Genesis, that lets you spawn your own, and then grow it with the same spell cast on the existing one. If time isn't an issue, you can conceivably spend 1000 years growing a node the size of Jupiter, and enjoy an absolutely absurd CL/ML boost with an equally absurd number of free metamagic levels (or free PP for augmenting) and spells/powers known/available (in the case of Vancian casting).
