Overview
Teams leave Sierra Interactive for Twenty CRM when monthly SaaS costs outweigh the value of integrated IDX and lead-gen tools, or when they want full infrastructure ownership. The migration carries all records Sierra exposes via export — People, Companies, Opportunities, Notes, and Tasks — into Twenty's People, Companies, and Opportunities objects with original create dates and owner assignments preserved. The harder translation problems are Sierra's Action Plans (automated email/text/voicemail sequences) which have no equivalent in Twenty's workflow builder; Sierra's Lead Ponds and lead-routing rules which require custom field logic and workflow conditions to approximate; and saved searches which land as custom text fields rather than native filter objects. FlitStack AI exports Sierra data via the API or UI export, transforms field names and pick-list values to match Twenty's schema conventions, creates any missing custom fields in Twenty's Settings → Data Model before import, and runs a sample migration with field-level diff before the full cutover. Our scoped read access means your Sierra team keeps working throughout the process, and a 24–48 hour delta window captures any in-flight changes at cutover.
Every standard and custom field arrives verified.
AI proposes the map; you confirm before any record moves.
Parent–child, lookups, and ownership stay linked.
Calls, emails, meetings — with original timestamps.
Documents, uploads, and inline notes move with the record.

Object mapping
Each row shows how a Sierra Interactive object lands in Twenty CRM, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Sierra Interactive
Lead
Twenty CRM
People
1:1Sierra's Lead object maps directly to Twenty's People object. All standard contact fields (name, email, phone, address) transfer as-is. Sierra-specific fields like lead source and tags become custom fields in Twenty's Data Model before import. Owner assignment resolves by email match to Twenty workspace members.
Sierra Interactive
Company
Twenty CRM
Company
1:1Sierra's Company object maps 1:1 to Twenty's Company object. Company name, website, address, and industry fields transfer as direct mappings. Sierra company phone and revenue fields map to custom number/text fields in Twenty. Parent-child company hierarchies preserve using the parentId relationship.
Sierra Interactive
Deal
Twenty CRM
Opportunity
1:1Sierra Deals map to Twenty Opportunities. Deal name becomes Opportunity name; deal value maps to Opportunity amount; pipeline stage names map via value_mapping to Twenty's stage pick-list. Close date transfers as-is. Pipeline assignment becomes a custom select field in Twenty since there is no native pipeline object.
Sierra Interactive
Note
Twenty CRM
Note
1:1Sierra notes on leads or companies migrate to Twenty Notes attached to the corresponding People or Company record. Original timestamps and author information (resolved by email) attach as metadata fields. Rich-text formatting in Sierra notes converts to plain text for Twenty's Note field.
Sierra Interactive
Task
Twenty CRM
Task
1:1Sierra tasks linked to leads or deals map to Twenty Tasks on the corresponding People or Opportunity record. Task subject, due date, completion status, and assigned user (via email match) all transfer. Task type (call, email, other) becomes a custom select field in Twenty since there is no native task-type classification.
Sierra Interactive
Lead Pond
Twenty CRM
Custom Field
1:1Sierra Lead Ponds (grouped lead buckets) have no Twenty equivalent. Each unique Lead Pond name becomes a custom select field on the People object in Twenty's Data Model. The import script populates this field for each contact based on the source pond assignment. Admins recreate pond logic as filter views in Twenty.
Sierra Interactive
Saved Search
Twenty CRM
Custom Field
1:1Sierra saved searches stored per lead become a custom text field (Saved_Search_Criteria__c) on the People record in Twenty. The raw search criteria string transfers as-is. If the saved search has a name, that name becomes a custom select value for easier reporting. Teams rebuild active searches as Twenty views with matching filter conditions.
Sierra Interactive
Saved Listing
Twenty CRM
Custom Field
1:1Sierra saved listings per lead have no Twenty equivalent. The listing MLS number, address, and save date migrate as custom text fields on the People record. If multiple listings are saved per lead, the most-recently-saved listing is marked as primary and others surface as additional text entries. Teams needing full listing history use a custom object in Twenty.
Sierra Interactive
Action Plan
Twenty CRM
Workflow (manual rebuild)
1:1Sierra Action Plans (automated email, text, voicemail, and task sequences) do not migrate. They are exported as a structured JSON document that lists every sequence, trigger condition, and action step. This document serves as the specification for rebuilding equivalent logic in Twenty's workflow builder or an external sequencing tool like Lemlist or Saleshandy.
Sierra Interactive
Lead Tag
Twenty CRM
Custom Field
1:1Sierra lead tags become a custom multi-select field (Lead_Tags__c) on the People object in Twenty. Tag values are enumerated from Sierra's tag list during the audit phase and mapped value-by-value. Multi-select allows a single contact to carry multiple tags. Admins rebuild tag-based routing in Twenty as workflow conditions or view filters.
Sierra Interactive
User / Owner
Twenty CRM
Workspace Member
1:1Sierra users and deal owners map to Twenty workspace members. The mapping resolves by matching Sierra user email to Twenty member email. Any Sierra owner without a corresponding Twenty member is flagged before migration; those records assign to a fallback owner or land in an unassigned state pending team onboarding in Twenty.
Sierra Interactive
Lead Source
Twenty CRM
Custom Field
1:1Sierra's lead source field (e.g., website, referral, PPC) maps to a custom select field (Lead_Source__c) on the People object in Twenty. Each Sierra source value is enumerated and mapped to a corresponding Twenty pick-list option. If a source value has no match, it creates a new pick-list entry before migration.
Sierra Interactive
Attachment / File
Twenty CRM
Attachment (via import)
1:1Sierra file attachments on leads, companies, or deals migrate as Twenty attachments linked to the corresponding record. File size limits follow Twenty's standard attachment constraints. Inline images in notes are extracted, re-hosted, and the URLs updated in Twenty's note body.
Sierra Interactive
Website / IDX Data
Twenty CRM
Not Migrated
1:1Sierra's IDX website data, listing inventory, and site analytics are outside the CRM data model and do not migrate. These are separate systems. Teams migrating away from Sierra's IDX platform need to select a new website host and re-integrate MLS feed data independently of the CRM migration.

Gotchas + challenges
Platform-specific issues from each side, plus the pair-specific challenges that don't show up on either platform's page on its own.
Sierra Interactive gotchas
Sierra API lacks public bulk export endpoint
Action Plans are not transferable as structured automation
Setup fee and pricing opacity create budget surprises
Lead Ponds have no equivalent in standard CRM schema
Website ownership stays with Sierra — DNS and SEO implications
Twenty CRM gotchas
Import order is enforced and critical
Export limited to 20,000 records and visible columns only
Soft-deleted records count toward uniqueness and trigger restores
API rate limits cap at 200 req/min on Organization tier
No native email sequences — follow-up cadences require external tools
Pair-specific challenges
Migration approach
Audit Sierra data and design Twenty schema
We extract a full data inventory from Sierra via API and UI export: People, Companies, Opportunities, Notes, Tasks, Tags, Lead Sources, Lead Ponds, and saved listings. We count records per object, identify duplicate risks, and audit data quality. Simultaneously, we design Twenty's Data Model: creating the custom select fields for Lead Ponds, Lead Tags, Lead Source, Pipeline, and task type; inviting all team members so owner email resolution works during import; and setting up pick-list values that match Sierra's source values exactly.
Build Action Plan export-for-rebuild package
Before touching data, we export all Sierra Action Plans as structured JSON documents listing every sequence name, trigger condition (lead source, tag, pond, date range), action step (email/text/voicemail/task), time delay, and conditional branch. This document is the rebuild specification your team uses to reconstruct sequences in Twenty's workflow builder or a replacement sequencing tool. We include a step-by-step mapping table for each Action Plan showing the equivalent Twenty workflow logic.
Resolve owners by email and flag orphans
Sierra user and owner records resolve to Twenty workspace members by matching email addresses. Any Sierra owner without a corresponding Twenty member is flagged and reported before migration — you either invite that person to Twenty first or assign their records to a fallback owner. Unresolved owner references block import of the affected records until resolved, so owner mapping must complete before any People or Opportunity batches run. This pre-flight check prevents orphan records and ensures every migrated contact and deal has an assigned owner from day one.
Import in dependency order: Companies → People → Opportunities → Notes/Tasks
Twenty's foreign-key model requires Companies to exist before People (via companyId) and People before Opportunities (via personNextId). We run imports in strict sequence: Companies first, then People with their companyId lookups resolved, then Opportunities with their personNextId links. Notes and Tasks import last, attached to their parent People or Company records. Each batch generates a validation report before the next batch starts.
Run sample migration with field-level diff
A representative slice of 100–500 records migrates first — covering a mix of People, Companies, Opportunities, and Notes. We generate a field-level diff comparing Sierra source values against Twenty destination fields so you can verify Lead Pond mapping, pipeline-to-stage translation, saved search criteria transfer, and owner resolution before the full run commits. Any field mapping errors surface here for correction before production migration.
Cut over with delta-pickup window and audit log
Full migration runs against Twenty with a scoped read-only connection to Sierra. Your team keeps working in Sierra throughout the cutover. A 24–48 hour delta window captures any records created or modified in Sierra during the migration run. Every operation is logged in an audit trail. If reconciliation reveals missing or mismatched records, one-click rollback reverts the Twenty workspace to pre-migration state while we re-run the affected batches.
