Migrate from Zendesk to Trengo

MIGRATION OVERVIEW

Why teams migrate from Zendesk to Trengo

The core problem

There is no native migration path from Zendesk to Trengo; data must be moved via API-to-API extraction and transformation using custom tooling or third-party migration services. The two platforms use fundamentally different data models: Zendesk is built around a structured, relational ticket system with statuses, SLA timers, organizations, and custom objects, while Trengo is built around a flat, conversation-centric inbox with 7-day thread windows, Profiles, and Contact Groups. Critical Zendesk constructs — including Organizations with SLA enforcement, Side Conversations, Custom Objects (Sunshine), and Satisfaction Ratings — have no direct Trengo equivalent and require either data flattening, external storage, or deliberate data loss decisions. Custom field schema audits, status mapping, and membership relinking via separate API calls are required before any data transfer can be considered complete.

Why this matters for your migration

KEY CHALLENGES

What makes this migration complex

These are the architectural mismatches and technical hurdles specific to a Zendesk to Trengo migration.

Most Critical

Ticket-to-Conversation Model Gap

Zendesk tickets carry structured statuses, SLA timers, and relational IDs that must be flattened into Trengo's 7-day conversation model, which lacks equivalent state management or SLA enforcement.

Blocks all downstream imports if mapped wrong

Organization-to-Contact Group Mapping

Zendesk Organizations enforce SLA rules and appear in operational reports, whereas Trengo Contact Groups are used only for bulk messaging and labeling, requiring SLA logic to be rebuilt or abandoned entirely.

Custom Objects and Sunshine Data Loss

Zendesk Custom Objects defined via the Sunshine platform have no target entity in Trengo and must be exported separately to an external system, as no import path exists within Trengo.

Side Conversation Handling

Zendesk's Side Conversations — child threads within a ticket used for Slack, email, or partner communications — have no Trengo equivalent and must be flattened into ticket notes or discarded.

Custom Field Schema Incompatibility

Trengo's custom field support is less granular than Zendesk's, requiring a field-by-field audit to identify unsupported field types before migration begins to avoid silent data loss.

Historical CSAT Score Portability

Zendesk Satisfaction Ratings do not map cleanly to Trengo's CSAT feature, which is restricted to Pro plan and above, meaning historical satisfaction data may be unimportable or structurally incompatible.

MIGRATION RISK ASSESSMENT

Every migration risk, already solved

Migration between platforms is full of edge cases. Our engineers have identified every risk from Zendesk to Trengo and built proven solutions for each one.

High complexity

Tickets / Conversations

Zendesk's stateful ticket model (New, Open, Pending, On-Hold, Solved, Closed) must be remapped to Trengo's simpler status set and 7-day window logic, requiring custom transformation rules for every ticket record.
Organizations

Zendesk Organizations carry SLA enforcement and reporting relationships that are entirely lost in Trengo's Contact Groups, which function only as labeling and bulk-messaging containers.
Custom Objects (Sunshine)

Custom Object schemas defined in Zendesk Sunshine have no target entity in Trengo and cannot be imported, requiring external archival and a complete rethinking of any workflows that depend on them.
Side Conversations

Trengo has no equivalent to Zendesk's Side Conversations, so all child threads must be flattened into internal ticket notes or permanently discarded during migration.

Custom engineering

Custom Fields

Trengo supports custom fields but with less granularity than Zendesk, making a pre-migration field-type audit mandatory to identify which fields cannot be migrated without data loss or schema alteration.
Ticket Comments / Messages

Comment threading and the public-versus-internal distinction must be explicitly preserved during transformation, as chronological ordering and visibility settings do not transfer automatically.
Contacts / End Users

Zendesk End Users map to Trengo Contacts, but Trengo's Profile model groups multiple Contacts into a single identity, requiring deduplication logic to avoid creating fragmented customer records.
Macros / Quick Replies

Template text content from Zendesk Macros can be mapped to Trengo Quick Replies, but any conditional trigger logic embedded in Macros has no equivalent and must be manually rebuilt.

Clean transfer

Tags / Labels

Zendesk Tags map directly to Trengo Labels with no structural differences, making this one of the most straightforward entity transfers in the migration.
Help Center Articles

The Zendesk Guide category-section-article hierarchy maps structurally to Trengo's help center, making article content migration relatively low risk, though formatting and embedded media should be validated post-transfer.

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:

Speed of automation for bulk record migration
Precision of engineers verifying integrity and business logic
Pilot migrations and sandbox testing to catch issues early
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 Zendesk and Trengo 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:

Field mapping and transformation
Pagination, rate-limit handling, and throttling
Preserving conversation threads, attachments, and internal notes
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:

100% record-count parity between your Zendesk data and Trengo
Zero downtime during staged cutovers
99.9% attachment integrity (verified via checksum)
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 Zendesk or Trengo 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:

Custom fields, ticket forms, and workflows
Multi-brand or multi-language setups
Historical imports and partial (date-based) migrations
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 Zendesk to Trengo. Can't find what you're looking for? Talk to our team.

Is Trengo cheaper than Zendesk?

At small team sizes (under 20 agents), Trengo's flat pricing (€299–€499/mo) is significantly cheaper than Zendesk Suite at $55–$115/agent/mo. But Trengo's AI surcharges (€0.25/conversation), conversation caps, and WhatsApp pass-through costs can narrow the gap at higher volumes. Zendesk's add-ons (Copilot at $50/agent/mo, QA, WFM) can push per-agent costs above $200/mo.

What are the API rate limits for Zendesk vs Trengo?

Zendesk's rate limits are plan-dependent: 200 RPM on Team, scaling to 2,500 RPM on Enterprise Plus or with the High Volume API add-on. Incremental exports are capped at 10 RPM. Trengo allows 120 RPM on most endpoints, with import endpoints limited to 60 RPM. Both return 429 status codes when limits are hit.

Can I migrate data between Zendesk and Trengo?

Yes, but there is no one-click migration path. You need to use both platforms' APIs to extract and import data. Key constraints: Trengo's import endpoints are rate-limited to 60 RPM, Zendesk side conversations and custom objects have no Trengo equivalent, and timestamps must be explicitly set to preserve chronological order.

Is Zendesk or Trengo better for WhatsApp support?

Trengo is the stronger choice for WhatsApp-centric teams. WhatsApp is a first-class channel in Trengo with native integration and broadcast capabilities. Zendesk supports WhatsApp via its social messaging layer (Suite Team and up), but it is a bolt-on rather than a core design focus.

What is hardest to migrate between Zendesk and Trengo?

Multibrand structures, custom objects (Sunshine), side conversations, WhatsApp-native behavior, AI automations, and historical reporting semantics are the hardest because they do not map one-to-one between the two platforms. Attachments and inline images also require download-reupload-rewrite logic to avoid broken references.

How long does the Zendesk to Trengo 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 Zendesk 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 Zendesk to Trengo?

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.
