Enterprise SaaS Migration: Legacy Platform Sunsetting Program

A growing SaaS company needed to migrate 40+ enterprise clients off a legacy platform onto a new cloud-native product within a hard fiscal year deadline. Internal teams were stretched across new feature development, and the migration required careful client sequencing, data integrity validation, and hands-on customer communication management.

Placed an RTE and two Scrum Masters to establish a SAFe-aligned delivery cadence across engineering, customer success, and QA. Built a migration runbook and client sequencing plan, coordinated go/no-go decisions for each client wave, and served as the primary escalation point for enterprise client concerns during cutover windows.

All 40 enterprise clients migrated successfully within the fiscal deadline. Zero data integrity issues post-migration. 100% customer retention through go-live. Engineering velocity improved 18% by end of program due to cleaner team structures.
