Customers from an earlier system come over with Odoo's own import: Contacts → Import. Import the companies first, then the people, so each person lands under their company. The import needs the Customer levels: Administrator right.

What happens after the import

Odoo refuses a period start in the future or more than 12 months ago, a level for someone outside the levels, and a level of the wrong kind.
