SaaS Migration Services
SaaS migration services turn installed software, single-tenant deploys, or aging tools into a modern SaaS product. Spygar plans data mapping, dual-run, and tenant cutovers so customers do not lose trust mid-move.
SaaS Migration Services
We migrate schemas, users, files, and integrations—often while introducing multi-tenancy and new billing. Rehearsals and rollback plans are part of the engagement, not optional extras.
- Customers land with complete data
- Fewer surprise outages at cutover
- A maintainable SaaS target architecture
- Documented migration runbooks
