Storage planning should begin with the legacy footprint and the target data model, then calculate expected Salesforce data storage and file storage separately based on record volumes and attachment requirements. The forecast must also incorporate retention and archiving so that inactive historical information does not remain indefinitely in operational storage. This produces a realistic capacity model rather than a simple copy of legacy consumption. The key is to represent the requirement in the same layer where Salesforce evaluates that business state. Selecting an external archive may be part of the eventual solution, but the assessment first needs baseline usage, target-volume calculations, and a lifecycle strategy that explains how operational storage will be managed over time. This avoids mixing customer-facing product logic with downstream technical state or using integration code as a substitute for catalog and orchestration design. When the model is aligned correctly, the platform can validate the request, retain the required lifecycle information, and generate the appropriate downstream action without redundant processing. That improves auditability and makes later changes easier because administrators can adjust the relevant metadata rather than reworking multiple custom components.
