Overview
The Practice organizes client data around a flat contact-centric model with pipeline stages and tags as primary segmentation tools. HighLevel splits contacts, companies, and opportunities into three separate objects with a full pipeline management system and a workflow engine that triggers on CRM events. FlitStack AI maps The Practice's contact records into HighLevel Contacts and Companies, pipeline deals into Opportunities, and all tags into HighLevel's tag field. The migration carries timestamps, owner assignments, and custom field values but cannot replicate The Practice automations — those must be rebuilt in HighLevel's Workflow Builder using an exported definition reference. We use HighLevel's API with bulk CSV for large record sets, sequenced so foreign keys (CompanyId on Contacts, OpportunityId on Tasks) resolve correctly in order. A 24–48-hour delta window captures any records modified between the migration run and go-live.
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 The Practice 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.
The Practice
Contact
HighLevel
Contact
1:1The Practice contact records map 1:1 to HighLevel Contacts. All standard properties (name, email, phone, address) transfer directly. Notes attached to a contact in The Practice become Notes in HighLevel with a ContactId link. Tags transfer to the tag field.
The Practice
Contact Company (property)
HighLevel
Company
1:1The Practice stores the client company as a text property on the Contact. FlitStack first creates a Company record in HighLevel, then resolves the Contact's company property to the new Company.id and writes it as Contact.companyId. Unmatched company names create a Company record automatically.
The Practice
Pipeline / Deal
HighLevel
Opportunity
1:1The Practice deals map to HighLevel Opportunities. Pipeline name becomes the HighLevel Pipeline; deal stage maps to the corresponding stage within that pipeline. Deal amount, close date, owner, and custom properties transfer as Opportunity custom fields.
The Practice
Pipeline Stage
HighLevel
Opportunity Stage
1:1Each pipeline stage name in The Practice is mapped value-by-value to the matching HighLevel pipeline stage. Probability and forecast category are applied per HighLevel stage defaults unless custom values are specified. Stage-entry timestamps are preserved as Opportunity custom datetime fields.
The Practice
Tag
HighLevel
Contact Tag
1:1The Practice tag strings are transferred as-is to the HighLevel Contact tag field. HighLevel supports multiple tags per contact; each source tag becomes a separate tag value. Tag-based segmentation from The Practice is recreated as HighLevel contact filters.
The Practice
Custom Field (contact-level)
HighLevel
Custom Field (contact-level)
1:1The Practice custom properties on contacts are read and recreated as Custom Fields in HighLevel. Field type is inferred from the source value format — date fields, number fields, pick-list fields, and text fields each map to the closest HighLevel custom field type.
The Practice
Custom Field (deal-level)
HighLevel
Custom Field (opportunity-level)
1:1Deal-level custom properties in The Practice (e.g., deal_priority, deal_type) are created as Opportunity custom fields in HighLevel. The pipeline and stage already capture the primary deal context, so these custom fields add supplementary structured data.
The Practice
Note / Session Note
HighLevel
Note
1:1Notes written in The Practice (session notes, coaching summaries) are migrated as HighLevel Notes with the Contact linked via ContactId. Original create dates and author information are preserved in custom datetime and text fields on the Note.
The Practice
Owner / Team Member
HighLevel
User
1:1The Practice owner email addresses are resolved against HighLevel users by email match. Unmatched owners are flagged before migration so the team can invite them to HighLevel or assign a fallback user. Owner is written as Opportunity.ownerId and Contact.ownerId.
The Practice
Attachment / File
HighLevel
Files
1:1Files attached to contacts or deals in The Practice are downloaded, re-uploaded to HighLevel, and linked back to the corresponding record. HighLevel's 25MB per file limit applies; files exceeding this are flagged for splitting before the migration run.
The Practice
Calendar Event / Appointment
HighLevel
Calendar Event
1:1Scheduled appointments from The Practice are migrated as HighLevel Calendar Events linked to the contact record. Original start/end times, timezone (converted from Eastern to UTC), and assigned user are preserved.
The Practice
Custom Object
HighLevel
Custom Object
1:1The Practice custom objects (if present) map 1:1 to HighLevel custom objects. Relationships between custom objects are mapped using HighLevel's relationship field definitions. Any N:N associations require junction object setup in HighLevel.

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.
The Practice gotchas
No public API means all migration data must be extracted manually
Session recordings and large files require separate manual download
Client group and tag inheritance is not automatically preserved in exports
Contract PDFs are stored as linked files, not embedded records
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 The Practice data export and map to HighLevel schema
FlitStack connects to The Practice via scoped API read access and exports all contacts, companies, deals (opportunities), pipelines, tags, notes, and custom field definitions. We produce a data inventory showing record counts per object, tag cardinality, and custom field names with value samples. This inventory drives the HighLevel schema setup plan — which custom fields to create, which pipelines to build, and which tag values to expect on the HighLevel side.
Set up HighLevel pipelines, custom fields, and tag taxonomy
Before data lands, your HighLevel admin (or our team) creates the pipelines matching your The Practice stage names, adds the custom fields for non-standard contact and deal properties, and confirms the tag taxonomy. FlitStack delivers a structured setup checklist mapped directly from the data inventory so nothing is missed. Pipeline IDs and custom field IDs from this setup phase are fed into the field mapping config.
Resolve owners by email and sequence migration: Companies → Contacts → Opportunities → Notes and Events
Owner resolution runs first: every The Practice owner email is matched to a HighLevel User by email. Unmatched owners are flagged for manual resolution. Migration then sequences in dependency order: Companies are created first (no foreign key dependencies), then Contacts (with CompanyId resolved from the prior step), then Opportunities (with ownerId resolved and stage mapped per pipeline), then Notes and Calendar Events (with contactId resolved). This order ensures foreign keys are valid at write time.
Run sample migration with field-level diff
A representative slice — typically 100–500 records across contacts, companies, opportunities, and notes — is migrated first. FlitStack generates a field-level diff comparing source values against destination field values so you can verify tag transfer, custom field mapping, owner resolution, and date conversion. You approve the sample before the full run commits. Any mapping adjustments are made to the config before the production migration begins.
Execute full migration with delta pickup and rollback capability
The full dataset migrates using HighLevel's bulk CSV endpoint for high-volume objects and API calls for records requiring custom field writes. A 24–48-hour delta pickup window runs concurrently, capturing any new or modified records created in The Practice during the cutover period. An audit log records every record written, updated, or skipped. If reconciliation fails, one-click rollback reverts the HighLevel environment to its pre-migration state so the team can correct the mapping and restart without data loss.
