MIGRATION OVERVIEW

Why teams migrate from BambooHR to Lever

There is no native migration path from BambooHR's ATS to Lever. BambooHR uses a flat, application-centric model where candidates are tied directly to specific job applications. Lever uses an opportunity-centric model where a single Candidate Profile has multiple Opportunities attached to it.
The fundamental gap is data model architecture: BambooHR's disconnected application records must be consolidated into Lever's unified Contact → Opportunity structure without creating duplicate profiles that break reporting.
Every migration requires navigating BambooHR's API extraction limitations, Lever's strict 2 requests-per-second POST rate limit, and the complex logic of merging flat records into a relational CRM model.
KEY CHALLENGES

What makes this migration complex

These are the architectural mismatches and technical hurdles specific to a BambooHR to Lever migration.

Most Critical

Model Translation

BambooHR's flat application records must be split into Lever's distinct Candidate Profile and Opportunity objects. Failure to separate creates duplicate profiles.

Lever Rate Limits

Lever strictly limits application POST requests to 2 per second. Bulk imports require intelligent queueing and exponential backoff to prevent silent data loss.

BambooHR API Limitations

BambooHR's API has limited extraction capabilities. Candidate notes and attachments are difficult to extract and often missing from standard CSV exports.

Multi-Application Deduplication

A candidate who applied to three jobs must have one Lever Profile with three Opportunities. Creating separate profiles breaks reporting and forces manual merges.

Resume Extraction

BambooHR stores resumes as file IDs requiring separate API calls. Files must be downloaded individually and re-uploaded to Lever via its API.

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 BambooHR and Lever 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 BambooHR data and Lever
  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 BambooHR or Lever 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 BambooHR to Lever. Can't find what you're looking for? Talk to our team.

How do I export candidate notes from BambooHR?
BambooHR's native CSV export has limitations and often drops historical candidate notes. You must use the BambooHR API to extract complete candidate histories and attachments programmatically.
What is the Lever API rate limit for creating opportunities?
Lever strictly rate-limits application POST requests to 2 per second. Exceeding this limit will result in a 429 TOO MANY REQUESTS error, requiring your migration script to use exponential backoff.
How does Lever's data model differ from BambooHR?
BambooHR uses a flat, application-centric model where candidates are tied directly to specific jobs. Lever uses an opportunity-centric model, where a single candidate profile can have multiple distinct opportunities attached to it.
How long does the BambooHR to Lever 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 BambooHR 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 BambooHR to Lever?
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.
