MIGRATION OVERVIEW

Why teams migrate from Teamtailor to Ashby

Ashby does not offer an automated migration connector for Teamtailor. Teamtailor is a career-site-first ATS with a JSON:API relational model, while Ashby is an analytics-first ATS with an RPC-style API where errors hide inside HTTP 200 responses.
CSV import only transfers basic candidate profiles — losing all interview history, custom fields, notes, attachments, and application-to-job relationships. API-based migration is required for any meaningful historical data preservation.
Every migration must handle Ashby's HTTP 200 error trap, Teamtailor's 50-request-per-10-second rate limit, and the fragmented write path where custom fields require separate API calls after record creation.
KEY CHALLENGES

What makes this migration complex

These are the architectural mismatches and technical hurdles specific to a Teamtailor to Ashby migration.

Most Critical

HTTP 200 Error Trap

Ashby returns HTTP 200 with success:false for application errors; standard status code checks silently miss failures.

Fragmented Write Path

Custom field values require separate customFields.setValue calls after record creation, doubling API call count per candidate.

Rate Limit Orchestration

Teamtailor caps at 50 requests per 10 seconds while Ashby caps at 1,000 per minute — both constrain migration throughput.

Activity Data Loss

Teamtailor activities (stage movements, emails) have no write endpoint in Ashby and must be flattened to notes or lost.

Stage Mapping Ambiguity

Teamtailor's flexible per-job stages don't map 1:1 to Ashby's structured interview plans tied to specific feedback forms.

Complete Technical Guide

Teamtailor to Ashby Migration: The CTO's Technical Guide

Ashby has no automated Teamtailor connector. CSV import loses lifecycle data. API migration requires handling Ashby's HTTP 200 error trap and Teamtailor's 50-req/10s rate limit. Budget 2–4 weeks for DIY.

What does an Engineer-led migration mean anyway?

Speed & Accuracy: Our Blended Method

We blend automation (smart scripts, bulk APIs) with human expertise for speed without risk. Our engineers manually check every mapping, validation, and exception.

You get:

  1. Speed of automation for bulk record migration
  2. Precision of engineers verifying integrity and business logic
  3. Pilot migrations and sandbox testing to catch issues early
  4. Real-time validation reports and rollback readiness
Result: 50x faster migrations than manual imports — with near-zero error rates.

Handling the Tricky Tech and API Details

The Teamtailor and Ashby APIs each behave differently, which is where our engineers shine. We build custom logic to handle the data quirks where generic tools typically break.

We handcraft API logic for:

  1. Field mapping and transformation
  2. Pagination, rate-limit handling, and throttling
  3. Preserving conversation threads, attachments, and internal notes
  4. Syncing custom fields, SLAs, and macros without breaking structure
Our scripts: Natively retry failed calls, re-queue large attachments, and ensure data parity.

No Guesswork

We don't just promise smooth migrations—we measure and prove them. Every client receives a Migration Validation Report with all metrics.

Typical results across projects:

  1. 100% record-count parity between your Teamtailor data and Ashby
  2. Zero downtime during staged cutovers
  3. 99.9% attachment integrity (verified via checksum)
  4. Full automation and preservation of all business rules
Our standard: Includes full SLA preservation and 48 hours of engineer-assigned support post go-live.

We Adapt to Your Setup (Not the Other Way Around)

No two teams configure Teamtailor or Ashby exactly the same way—with unique automations and data. We customize every migration script to fit your exact workflow, tags, and triggers.

Our engineers adapt for:

  1. Custom fields, ticket forms, and workflows
  2. Multi-brand or multi-language setups
  3. Historical imports and partial (date-based) migrations
  4. Integration re-mapping for CRMs, chat, or feedback tools
The promise: If your data doesn't fit a standard template, we build one just for you.

FAQ

Frequently Asked Questions

Everything you need to know about migrating from Teamtailor to Ashby. Can't find what you're looking for? Talk to our team.

Can I migrate from Teamtailor to Ashby using CSV files?
Yes, but with severe limitations. Ashby's self-serve CSV import only supports basic candidate profiles — name, email, phone, LinkedIn. You lose all interview history, custom field values, notes, attachments, pipeline stage data, and application-to-job relationships. It's suitable for small teams that don't need historical hiring data.
Does Ashby support a native migration from Teamtailor?
Ashby's automated API migration connectors support Greenhouse, Workday, and some Lever migrations — not Teamtailor. Ashby does list Teamtailor on its file-based historical import route, which can import candidates, applications, optional jobs, and feedback as notes, but it does not import job postings, interview plans, or openings.
What are the API rate limits for Ashby and Teamtailor?
Ashby enforces 1,000 requests per minute per API key (15/min for report endpoints). Teamtailor allows 50 requests per 10 seconds and recommends a 300ms delay between requests. Since migrating one candidate with applications, custom fields, and notes requires 8+ API calls, a 10,000-candidate migration takes roughly 80+ minutes at maximum throughput.
Why does Ashby return HTTP 200 for API errors?
Ashby's API uses an RPC-style architecture where application-level errors return HTTP 200 with a 'success: false' flag and an errorInfo object in the response body. Standard HTTP status code checks will miss these errors entirely. Migration scripts must parse the response body and check the success field on every call.
How long does a Teamtailor to Ashby migration take?
A CSV-only migration can be done in a day but loses most data. Ashby's file-based historical import takes days with Ashby's involvement. A custom API-based migration takes 2–4 weeks of engineering effort including scripting, testing, and validation. A managed migration service typically completes the full transfer in days, including validation.
How long does the Teamtailor to Ashby migration take?
Most migrations complete within 1–5 business days, depending on data volume and complexity. We provide a detailed timeline after the initial assessment and can often complete small migrations in under 24 hours.
Will my team lose access to Teamtailor during the migration?
No. Your source system remains fully operational throughout the entire migration. We run the migration in the background with zero downtime to your current operations.
Will there be downtime when migrating from Teamtailor to Ashby?
No. Our migration process is designed for zero downtime. We use a staged approach with background sync and a fast cutover, ensuring no disruption to your live business operations.
How do I validate that everything migrated correctly?
Every client receives a Migration Validation Report with comprehensive metrics including record-count parity, attachment integrity verification via checksum, and full audit logs. We also offer unlimited sample migrations so you can verify before committing.
Do I need professional help for this migration?
While simple migrations can sometimes be handled in-house, professional help ensures zero data loss, proper field mapping, and preservation of relationships between records. Our engineer-led approach catches edge cases that automated tools miss.
Does ClonePartner provide guidance before committing?
Yes. We provide a free consultation and assessment. We'll review your data structure, discuss your requirements, and provide a detailed migration plan and fixed-price quote before you commit to anything.
