MIGRATION OVERVIEW

Why teams migrate from Help Scout to Kustomer

There is no native migration path from Help Scout to Kustomer. Help Scout uses a mailbox-based shared inbox model with conversations, customers, and simple tag-based organization, while Kustomer organizes everything around a unified customer timeline where all interactions link to a central customer profile.
The core challenge is schema preparation: Kustomer requires custom attribute metadata to be defined before any data can land, and Help Scout's two-tier Docs hierarchy (Collections and Categories) must be flattened into Kustomer's single-tier category model.
Every migration requires admin-privileged tokens for timestamp preservation, mandatory article versioning for KB visibility, and careful use of the importedAt property to bypass standard rate limits during bulk imports.
KEY CHALLENGES

What makes this migration complex

These are the architectural mismatches and technical hurdles specific to a Help Scout to Kustomer migration.

Most Critical

Custom Attribute Schema

All custom data slots must be defined in Kustomer before import. Missing attributes cause data to be silently dropped.

KB Article Versioning

Creating an article in Kustomer is not enough — a Version must also be created to make the content visible in the help center.

Timestamp Preservation

Original creation dates are only preserved when using admin-privileged API tokens. Standard tokens stamp the import time.

Docs Hierarchy Flattening

Help Scout's two-tier structure (Collections and Categories) must be flattened into Kustomer's single category model.

Pros and cons of different migration options

Choosing the right approach is key because migrating from Help Scout to Kustomer isn't just about moving data – it's about protecting customer relationships.

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 Help Scout and Kustomer 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 Help Scout data and Kustomer
  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 Help Scout or Kustomer 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.
