If your first BitTitan jobs are running directly against production mailboxes with no pilot validation, you are taking on avoidable risk.

A BitTitan pilot migration is designed to confirm your full configuration using a small, representative set of real production accounts before you begin pre-stage at scale. It is not a separate test environment. The pilot uses real production accounts, real BitTitan endpoints, and the same source and destination tenant configurations you will use for the wider migration.

Pick pilot accounts that reflect the variety in your environment. Include at least one small mailbox, one large mailbox, one mailbox with delegates, one shared mailbox, and one account with a non-standard UPN format. A pilot made up only of small, standard mailboxes will not reveal how your configuration behaves with large or atypical accounts.

After the pilot completes, do not rely only on job status. Validate the destination manually before calling it a success: sign into Outlook on a test device connected to the destination tenant, confirm email and calendar access, verify delegate access where applicable, and confirm send and receive. If OneDrive is in scope, also confirm OneDrive sync.

A pilot that passes and includes confirmed destination access across in-scope workloads should be the gate that must be cleared before pre-stage begins. If you skip that gate, configuration issues tend to surface later at scale during pre-stage.

Are you running a BitTitan pilot with representative accounts and manually verifying destination access before starting pre-stage?
