Gateway Migration Programme
A twelve-week programme to move from one primary gateway to another with minimal involuntary churn.
Brief
Migrating a live subscription book between gateways is rarely a code problem; it is a coordination problem. We run the programme: tokenisation, network token transfers, reconciliation, fallback design, and a phased cutover that keeps revenue intact. Engineering remains in your team. We bring the playbook.
Inclusions
- Migration runbook tailored to your platforms
- Network token transfer coordination with both processors
- Phased cutover plan with rollback gates
- Daily reconciliation tooling spec
- Weekly steering review with finance and engineering
- On-call presence during cutover weekends
What you will hold at the end
- Migration completed with documented churn impact
- Reconciliation parity between old and new platforms
- A repeatable playbook your team owns afterwards
Common questions
From earlier engagements
★★★★★
"They ran the migration like an air traffic control tower. Calm, structured, and very clear about who owned what."
"The reconciliation tooling spec was the deliverable that made our finance team trust the cutover."
★★★★☆
"The programme overran by two weeks because of a vendor delay. The team flagged it early and re-planned, which is what I wanted."
"Worth the budget for the on-call weekends alone."
