What is the safest way to switch compliance platforms without losing audit history?

Quick answer

Switching compliance platforms is safe if you treat your audit history as the asset it is. Export policies, risks, evidence, and audit logs from the old tool, import them into the new one as baseline data, and keep read access to the old system until your next audit passes. OptiTech imports CSV data and documents, and its append-only evidence log means everything you collect from day one is timestamped and tamper-evident.

Why teams switch

Common triggers for replacing a compliance tool:

The tool doesn't cover your regulations. US-built platforms often treat NIS2 as a generic checklist rather than mapping the actual Swedish Cybersecurity Act and MSB regulations, and none of them file incident reports to Swedish authorities.
Cost. Annual contracts in the 20,000 to 50,000 USD range are hard to justify for a 40-person company.
Data residency. Your customers or your legal team require compliance data to stay in the EU. OptiTech stores everything in Swedish and EU data centers.
Manual overhead. The tool turned out to be a document library with a dashboard, not automation.

The migration plan

Export from the old platform before you cancel: policies, control lists, risk register, supplier data, evidence archives, and audit logs. Get raw files, not just PDFs, where possible.
Import baseline data into OptiTech. Risks, suppliers, and assets go in via CSV; policies upload as documents with version history starting fresh.
Reconnect integrations. Evidence collection starts immediately, so your new trail begins on cutover day with no gap.
Run in parallel briefly. Keep the old tool in read-only mode until your next audit or certification review has passed, so you can answer questions about historical evidence.
Archive the export. Store the full old-platform export in your document archive; auditors rarely need it, but regulators can look back years.

What you can't afford to lose

The audit trail matters more than the documents. A certification body checking ISO 27001 continuity, or a supervisory authority investigating an incident, may ask for evidence from before the switch. As long as you hold a complete export and can show an unbroken trail in the new platform from cutover, a platform switch is a non-event in an audit.
