This is a good question! Currently Pulse does not consider the the schedule of migration packages. But I believe this is very interesting enhancement request (ER). Could you please contact your local Cubewise support office? They will perform the ER through our ticketing system.
Scheduling is something that we have on our enhancement list. We don’t have plans to implement it at this stage for a few reasons, the main one being we don’t want unattended migration. If something goes wrong during the execution of the package it is important that someone is available to fix issues or roll back changes.
