Overview
Sierra Interactive structures its CRM around a real estate data model: leads carry agent-assignment fields, saved searches reference IDX listings, and action plans drive automated follow-up sequences tied to property-viewing behavior. HighLevel uses a general CRM model with contacts, companies, pipelines (opportunities), tags, and custom objects — no native IDX listing association and no bundled website builder. The migration carries all standard records (leads, contacts, companies, deals, tasks, notes) but requires custom field creation for Sierra-specific properties like lead_grade, source_campaign, and the lead-pond reference. Saved searches do not have a native HighLevel equivalent and must be rebuilt as smart lists or tag-based filters. Action plans and automations — which drive the bulk of Sierra's behavioral follow-up logic — do not migrate; FlitStack exports the action plan definitions as a structured JSON reference for your HighLevel admin to rebuild in the Workflows builder. The migration runs via Sierra's REST API (authenticated with an API key in the Sierra-ApiKey header) into HighLevel's Contacts and Opportunities API endpoints, using bulk CSV import for large record sets and delta-wINDOW pickup for in-flight changes during cutover.

Object mapping
Each row shows how a Sierra Interactive object lands in HighLevel, 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
HighLevel
Contact
1:1Sierra leads map directly to HighLevel contacts. All standard lead fields (name, email, phone, address) transfer as Contact fields. Owner assignment resolves by email match to HighLevel users. Leads without an email address are flagged for manual review before migration.
Sierra Interactive
Company
HighLevel
Company
1:1Sierra company records map one-to-one to HighLevel companies, transferring company name, website/domain, industry, and employee count as standard fields. When a Sierra lead has multiple company associations, the primary company is set as the main link in HighLevel, and secondary associations are added as additional linked records. The migration validates each Sierra company ID against HighLevel; any unmatched companies are flagged for review.
Sierra Interactive
Deal
HighLevel
Opportunity
1:1Sierra deal records map to HighLevel opportunities, converting the deal name to opportunity name and the deal amount to monetary value. Pipeline stage is mapped via a pre‑approved value map to the matching HighLevel stage; if the pipeline does not exist, it is created. Deal close date and owner (resolved by email) transfer as well, with custom fields migrated after validation.
Sierra Interactive
Action Plan
HighLevel
Workflow
1:1Sierra Action Plans (automated email, SMS, ringless voicemail, and task sequences) have no direct HighLevel equivalent. We export Action Plan definitions as a structured JSON reference so your HighLevel admin can rebuild each sequence in the Workflows builder, using the same step order and trigger conditions.
Sierra Interactive
Saved Search
HighLevel
Smart List / Custom Object
1:1Sierra saved searches (filter objects on property type, price range, neighborhood, listing status) have no native HighLevel equivalent. We export saved search definitions with their filter criteria. They must be rebuilt as HighLevel Smart List filters or as custom object records, tagged per lead.
Sierra Interactive
Task
HighLevel
Task
1:1Sierra lead tasks, such as call and follow‑up tasks, map to HighLevel tasks, preserving original due dates, task descriptions, and owner assignments. Task completion status transfers as‑is, and tasks without an owner receive a migration fallback user. If a task includes priority or recurring details, those are stored as custom fields for manual recreation in HighLevel. All due dates are converted to the target user's timezone.
Sierra Interactive
Note
HighLevel
Note
1:1Sierra notes attached to leads or deals transfer to HighLevel notes. Note body, author (owner), create date, and parent record link (contact or opportunity) are preserved. Rich-text formatting is converted to plain text where HighLevel's note format does not support HTML.
Sierra Interactive
Lead Pond
HighLevel
Tag / Custom Field
1:1Sierra Lead Ponds are lead categorization buckets (e.g., Hot, Warm, Cold) that group leads by priority. We map pond names to HighLevel tags on the contact record, preserving the pond label. Leads can belong to multiple ponds — all pond assignments migrate as tag values.
Sierra Interactive
Attachment / File
HighLevel
File (via URL reference)
1:1Sierra file attachments on leads or deals (e.g., contracts, pre-approvals) are exported with their download URLs. We re-upload files to HighLevel's file storage and attach them to the corresponding contact or opportunity record. File size limits and format compatibility are validated during migration.
Sierra Interactive
Custom Lead Field
HighLevel
Custom Field on Contact / Opportunity
1:1Sierra custom lead properties such as lead_grade, source_campaign, referral_partner, mortgage_status, and others require new custom fields in HighLevel. Before migration, FlitStack creates each field matching the Sierra type—text, number, pick‑list, or multi‑select—and populates allowed values for choice fields. Values are mapped one‑to‑one, and any Sierra pick‑list value not in HighLevel’s options is flagged for admin review. A post‑migration validation report confirms that all custom field values transferred correctly.

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
HighLevel gotchas
Sub-account architecture creates isolated data silos per client
Usage-based telecom and AI costs are not in the subscription price
Workflows have no native equivalent in most destination CRMs
API rate limits cap bulk migration throughput at 100 requests per 10 seconds per sub-account
White-label configuration and branding assets do not export via API
Pair-specific challenges
Migration approach
Audit Sierra data model and export custom field inventory
FlitStack connects to Sierra Interactive via API using the Sierra-ApiKey header. We retrieve the full object schema — standard fields on Lead, Company, Deal, Task, Note — and identify all custom fields defined in your Sierra account. We also pull your Action Plan definitions (step order, trigger conditions, action types) and Lead Pond list. This inventory drives the field mapping document and the custom field creation checklist for HighLevel. Any field with no HighLevel equivalent is flagged for custom field creation before migration begins.
Create HighLevel custom fields and pipelines from the mapping plan
Based on the mapping document, FlitStack creates the custom fields in HighLevel (Lead Grade, Campaign Source, Referral Partner, Mortgage Status, Property Type Interest, Budget Range, Original Create Date, Saved Search Ref, Source System ID). We also create the pipeline(s) in HighLevel matching your Sierra deal pipeline names and stage values. If a pipeline does not exist, we create it before the migration run. All custom field API names are confirmed against HighLevel's field naming conventions before records are loaded.
Resolve owners and run sample migration with field-level diff
Sierra agent assignments resolve to HighLevel users by email match. Any Sierra owner without a corresponding HighLevel user is flagged before migration — your team either creates the HighLevel user or assigns a fallback owner. A representative sample (typically 200–500 records spanning contacts, companies, deals, and tasks) migrates first. We generate a field-level diff comparing source values to destination values for every mapped field. You review the diff and approve before the full migration commits. This is the last chance to correct mapping errors before volume migration.
Run full migration with delta-pickup window
The full record set migrates in sequenced batches: companies first (to populate the Company lookup for contacts), then contacts (with lead-pond tags applied and owner assignment resolved), then deals (with pipeline and stage mapping applied), then tasks and notes (with parent record links verified). A 24–48 hour delta-pickup window runs simultaneously, capturing any records created or modified in Sierra during the migration window. The delta records are merged into HighLevel before final reconciliation. Audit log records every operation.
Reconcile, validate record counts, and deliver migration report
After the delta window closes, FlitStack runs a reconciliation check comparing Sierra record counts to HighLevel record counts per object type. Any discrepancies (missing records, unmatched foreign keys, unassigned owners) are surfaced in a corrective-action report. We deliver the Action Plan export JSON and Saved Search definitions as separate files for your HighLevel admin to reference during the rebuild phase. One-click rollback is available for 72 hours post-migration if reconciliation reveals systemic issues requiring a re-run.
