Why ATS migrations break

Candidate profiles transfer. Context doesn’t. Interview scorecards vanish. Pipeline stage history flattens into a single status. Custom screening questions lose their structure, and rejection reasons disappear. Most migration tools handle basic candidate records and quietly discard everything else. We reverse-engineer your full ATS schema, build transformation logic for every object type, and validate in dry runs before touching production.

Full pipeline history preserved

Stage transitions, timestamps, rejection reasons, and recruiter assignments. The complete recruiting timeline, not just the current status.

Zero recruiting downtime

Migration runs parallel to your live system. Your team switches over in one afternoon.

Custom fields mapped

Scorecards, screening questions, EEO data, custom tags. Transformed to match your new platform’s structure.

Any platform, any direction

Greenhouse, Lever, Workable, BambooHR, iCIMS, Recruitee, spreadsheets, legacy databases.

What most teams try first

CSV export and reimport

The appeal

Every ATS has an export button. Download candidate data, clean it in a spreadsheet, upload to the new system.

Where it breaks

Basic candidate info lands. Interview notes, pipeline history, and attachment links don’t. You get names without context.

Built-in migration wizard

The appeal

Some ATS platforms offer import tools for popular source systems.

Where it breaks

Standard candidate fields transfer on the happy path. Custom scorecards, multi-stage workflows, and hiring team assignments get dropped or flattened.

Manual re-entry

The appeal

Only move active candidates. Start fresh with a clean database.

Where it breaks

Works until someone needs to reference a past hire’s interview notes, or compliance requires you to retain rejection records. History has value.

Built for these situations

Recruiting teams switching ATS platforms with thousands of candidates and years of pipeline history worth preserving
Companies consolidating multiple ATS tools or regional systems into one platform
Organizations that ran a basic import and discovered interview notes and custom fields arrived broken or missing
HR leaders who can’t pause active hiring while the migration happens

Why teams choose Stratalis for ATS migration

Flat-rate pricing

You know the full cost before we start. No hourly billing, no surprise overruns when scope gets complicated.

Engineers, not account managers

You talk directly to the people writing the migration scripts. No layers between your question and the answer.

Messy data is our day job

We build data pipelines from unstructured web sources for a living. ATS schemas are well-documented by comparison.

Rollback on every cutover

No data is overwritten until validation passes. If anything looks off, we revert to your pre-migration state in minutes.
