This paper investigates the most favorable conditions for a full defragmentation procedure when evolving from a fixed to a flexible-grid scenario. Results show that migrating legacy channels to flexible-grid formats can yield up to 50% more capacity for future traffic, provided these legacy channels are also spectrally re-planned.
