What is user migration?

User migration, often called bulk import, transfers customer account records into a new identity system before customers begin signing in through it, rather than migrating one account at a time as customers authenticate.

Frequently asked questions

How is bulk import performed?

Depending on volume: through an API for smaller migrations, an API with increased rate limits for mid-size migrations, or a CSV-based import with vendor support for very large migrations.

Is bulk import used on its own or alongside other approaches?

Both. It can be a standalone migration strategy or a subsequent step after just-in-time migration, to migrate any remaining accounts that haven't yet signed in.

Building the integration, not choosing it?Definitions stop where implementation starts. The developer docs carry the API references, SDKs and SCIM endpoints.
