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.
