## Purpose [Overall Account Data Architecture Proposal documentation](https://gitlab.com/gitlab-org/customers-gitlab-com/-/blob/main/doc/architecture/account_data_architecture_proposal.md) In https://gitlab.com/groups/gitlab-org/-/epics/8331+, we are updating the data architecture of CustomersDot, in particular the existing `Customer` model (to be renamed `User`), to better align with Zuora's data structure. This iteration will focus on the last phase of this data architecture rollout; the clean-up. When the new models are being used, the legacy data models, and in particular the references to `customer_id`, both in code and in the database, should be removed.
