The projected Pokemon nest migration did not happen. Now there is no way to know when the next migration will happen.
The Nest Atlas at The SilphRoad does not need an update. The Pokemon Go trainer community was expecting the third Pokemon Nest migration to happen in Friday or Saturday. This projection was based on the time lapses between the first two migrations.

Niantic has been changing Pokemon nests in two migrations that happened after 23 and 24 days respectively. The third Pokemon nest migration would have been due this weekend. It did not happen. Now there is no way in knowing when there will be another nest migration. It is expected that there will be somewhen another nest migration. Migrations are not a game mechanic. It is likely a manual action.
Many trainers hoped their local nests would change so they can harvest a new kind of Pokemon. Nests allow trainers to collect many Pokemon of the same time at the same location for a long period of time. Nests do not move. The spawns are not triggered by terrain. Nests are special locations where certain Pokemon appear all the time.
One reason why Niantic did not stage a migration this weekend might have been the launch of Pokemon Go Plus. The migration would have added more complexity to the launch. The run on the Pokemon Go Plus on Friday was huge. The Pokemon Go Plus Bluetooth gadget has sold out within 24 hours. Right now there is no way to buy a Pokemon Go Plus online and in stores. It is completely sold out. Nintendo will be releasing more over the coming weeks.
Niantic CEO John Hanke has recently said that he believes Pokemon Go will be around for years to come. There will be soon real world social events that glue the trainer community together. At these events new generations of Pokemon come to live. The journey of Pokemon Go has just begun.
