Zero-Downtime CRM Migration to Salesforce with 100% Data Integrity
A growth-stage B2B SaaS company was running on a legacy CRM and disconnected marketing systems, and couldn't afford downtime or data loss during a migration. SiyaSphere designed a migration-first RevOps strategy with data normalisation, AI-assisted validation, and human QA on every migration. The move completed with zero downtime and 100% historical data integrity, and GTM execution ran 50% faster afterwards.

The challenge
- A legacy CRM and disconnected marketing systems were slowing the GTM team down.
- A critical data migration was needed with zero tolerance for downtime or data loss.
- There were concerns about the integrity of historical data.
What we built
- 1
Migration-first RevOps strategy
Planned the target data model and GTM processes before moving any data, so the new system was built for how the team would work.
- 2
Data normalisation
Cleaned and normalised records into a consistent model ahead of migration.
- 3
AI-assisted validation
Used AI checks to validate records at scale and flag anomalies before and after each load.
- 4
Human QA on every migration
Had people review every migration batch so nothing went live without sign-off.
Results
- Zero-downtime data migration
- 100% historical data integrity
- GTM execution 50% faster after migration
- A modern, scalable tech stack
- Improved data reliability
Key takeaway
Migrations fail when they copy old problems into a new system. Designing the target model first, then validating with both AI and people, is what makes zero downtime and full integrity achievable.
