Can I schedule a migration to automatically start/stop at a specific time?
Migrations can be scheduled to start at a specific time. There is no option to have the migration stop or pause at a scheduled time.
For specific instructions on starting a migration, see How do I start a migration?
If, at any point, you wish to change the start date and time of the migration you have selected to begin, simply stop the migration and start it again with different date settings. Be aware that it may take some time to stop, and will remain in the "Stopping" state until it is ready to be started again. Once the status has changed from "Stopping" to "Stopped", you will be able to resume the migration.
If there are concerns about bandwidth usage, it is possible to specify how many mailboxes to migrate concurrently within a project. Use the instructions in How do I specify how many items to migrate simultaneously? MigrationWiz will only open one (1) connection per mailbox. Therefore, setting a low concurrency value on your connector is an effective way to control bandwidth usage. MigrationWiz will automatically start new migrations as others complete.
