How to cleanly remigrate a user’s calendar.
You may need to remigrate a user’s calendar if there are changes to the user’s calendar after
initial migration. To completely remigrate a user’s calendar, follow these steps:

2. Configure the Migration tool to migrate the Calendar and select the option “Migrate all data
(overwriting previously migrated data)”.
