We propose a novel Optical Network Units (ONU) migration mechanism within the Time and Wavelength Division Multiplexed PON (TWDM-PON) framework by rearranging the working ONUs to a minimum number of wavelengths and turning off the rest to save power. We show through simulation that the number of working wavelengths can be minimized up to a theoretical lower bound, e.g. 23%, under the typical ONU online profiles. We further investigate how the migration interval and delay influence the user Service Level Agreement (SLA). We find that under the example ONU online profiles, 99.99% ONU SLA can be realized with the migration delay of 1000 milli-seconds. However to realize 99.999% ONU SLA, the migration delay must be 100 milli-seconds or lower.
