Leave legacy PACS. We manage the move.

Go-lives take anywhere from 1 to 12 months. Overlay go-lives take a matter of weeks. Involved PACS migrations typically run 3 to 9 months, and the pace is set by the PACS the data is coming out of, not by Sirona. How long the historical archive takes depends on its size, your bandwidth, and how many interfaces are involved — and it transfers in the background while reading continues. Sirona gives you a detailed schedule during planning.

No. Your existing PACS remains fully operational throughout migration. Historical data transfers in the background, integration testing happens in parallel, and the cutover itself is a routing change rather than a big-bang event.

All historical studies migrate to Sirona's cloud archive with per-study validation — metadata comparison, pixel checksums, and completeness confirmation. Radiologists have full access to priors in Sirona.

Yes. During parallel running, new studies route to both systems simultaneously. After cutover, you can keep the legacy system running read-only for a transition period, or decommission immediately.

Sirona's migration team leads the project. Your IT team participates in decisions and provides environment access, but Sirona handles assessment, planning, data transfer, validation, and go-live coordination.

Any study with a detected discrepancy is automatically re-transferred and re-validated. Studies that still can't be validated — for example, files that are already corrupt in the source archive — are reported to you for a decision before the migration is closed out.
