BitTitan supports multiple migration strategies that can cater to different requirements and scenarios.
A single pass migration will move everything once mail are switched over. Such migration is suitable for large numbers of smaller mailboxes and it is simplier to implement.
A multi-pass migration will move majority of the data prior to cutover and the run a full pass thereafter. Time taken to migrate is greatly reduced at the final pass. (Sync updates, deletes and changes post pre-stage may not be updated.)
Documentations for migration support different requirements are available, with instructions available for working GCP console, Office 365 Exchange/Azure portal. In migration from G-Suite, create of a Google Service Account may be required to mitigate throttling during migration. On Google, enabling of API needed for the project is required and App-based authentication is required for Sharepoint, OneDrive and Teams migration.
Most of the steps for different requirements are cover and available on BitTitan’s help portal.
