Cutover Strategy & Phased Execution Plan
A temporary and controlled ramp-down of operations is a standard industry best-practice for large-scale platform migrations. The objective is to mitigate risks to data, finance, and customer experience during the final cutover.
Proceeding without an operational pause necessitates the following reactive, high-effort mitigation plans, which will still result in a negative impact to customers and internal teams.
| Impact | Mitigation Plan (High-Effort & Reactive) |
|---|---|
| Payment settlement error. | The finance team must perform a manual payment settlement of all transactions, risking delays in financial closing. |
| "Stuck" & Lost In-flight Orders. | Operations team must manually reconcile and adjust every orders from old platform in the new system. CS team must manually call customers to manage fulfillment. |
| Marketplace Sync Failure. | No immediate mitigation is available from tech team. Sellers must re-sync the missing products manually. |
