Overview
Constructor CRM and HighLevel both manage contacts, companies, and deals, but the platforms diverge on automation philosophy and account structure. Constructor CRM stores deal pipelines and stage history in a flat configuration; HighLevel models opportunities inside named pipelines with a visual workflow builder. FlitStack AI extracts data from Constructor via scoped API access and CSV export, then maps Constructor's contact properties, company records, deal pipelines, and custom fields into HighLevel's contact, company, and opportunity objects. Owner resolution happens by email match against HighLevel users before records land. Custom fields from Constructor are recreated as custom fields in HighLevel before the migration run. Workflows, sequences, and automation rules from Constructor do not migrate — those require manual rebuild in HighLevel's Workflow Builder using a FlitStack-supplied export of your source automation logic as a reference. The cutover includes a delta-pickup window so any records modified during the switch are captured before you close out Constructor.
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 Constructor 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.
Constructor
Contact
HighLevel
Contact
1:1Constructor CRM contacts migrate directly to HighLevel contacts using a field-by-field mapping approach. Name, email, phone, and address fields map to their HighLevel equivalents. Owner resolution is performed using email address matching against existing HighLevel user accounts. Any unmatched owners are flagged in a pre-migration report for your team to resolve before the migration run proceeds.
Constructor
Company
HighLevel
Company
1:1Constructor CRM company records map to HighLevel companies with direct field-to-field correspondence. Company name, domain and website URLs, industry classification, employee count, and annual revenue fields migrate as their HighLevel equivalents. Parent-child company hierarchies that exist in Constructor are preserved through HighLevel's company association fields, maintaining your organizational structure in the destination system.
Constructor
Deal
HighLevel
Opportunity
1:1Constructor CRM deals map directly to HighLevel opportunities, converting deal records into the opportunity object format. Deal name, amount, stage, and close date migrate to HighLevel's opportunity Name, Value, Stage, and Close Date fields respectively. Pipeline membership from Constructor becomes the opportunity's assigned pipeline in HighLevel, ensuring deal context is preserved across the migration.
Constructor
Pipeline
HighLevel
Pipeline
1:1Constructor CRM pipelines map on a one-to-one basis to HighLevel pipelines, preserving your complete deal flow structure. Each Constructor pipeline is created as a named pipeline in HighLevel with matching pipeline configuration. Stage names are value-mapped to the corresponding HighLevel stage labels so that historical deal positions and progression through your sales process are fully preserved in the new pipeline system.
Constructor
Pipeline Stage
HighLevel
Opportunity Stage
1:1Constructor CRM stage names map value-by-value to HighLevel pipeline stages. Stage probability and order are reapplied from Constructor's stage configuration. If Constructor stages have custom probabilities, these are stored as a custom field in HighLevel since HighLevel stage probabilities are set per pipeline.
Constructor
Custom Field
HighLevel
Custom Field
1:1Constructor CRM custom fields (on contacts, companies, and deals) are recreated as custom fields in HighLevel before the migration run. We create each field with the appropriate type (text, number, date, pick-list) and then populate values during the migration. Field-level diff confirms all custom values landed correctly in HighLevel.
Constructor
Activity (Call, Email, Note)
HighLevel
Task / Note
1:1Constructor CRM calls and emails become HighLevel tasks with Type set to 'Call' or 'Email'. Notes migrate to HighLevel notes attached to the contact or opportunity record. Original timestamps, owners, and subject lines are preserved so the activity timeline in HighLevel reflects the full history from Constructor.
Constructor
Tag / Label
HighLevel
Tag
1:1Constructor CRM tags on contacts and deals migrate to HighLevel tags. Tags are preserved as text labels so segmentation logic in HighLevel workflows can reference the same tags. Tag count per record is noted during the migration so you can verify tag distribution in HighLevel.
Constructor
Attachment / File
HighLevel
File
1:1Constructor CRM file attachments are downloaded from source records and re-uploaded to HighLevel's centralized Files section. Each file is attached to the corresponding contact, company, or opportunity record in HighLevel. File size limits and original attachment URLs are preserved as HighLevel file records, maintaining referential integrity for your documentation and assets.
Constructor
Custom Object
HighLevel
Custom Object
1:1Constructor CRM custom objects map 1:1 to HighLevel custom objects. Custom object relationships in Constructor (one-to-many or many-to-many) are recreated using HighLevel's custom object relationship schema, including junction tables or linking objects where necessary. We deliver a detailed relationship diagram before migration so you can review how the custom object graph will look and function in HighLevel, allowing you to verify the data structure before the full migration proceeds.
Constructor
Workflow / Automation
HighLevel
Workflow Builder (manual rebuild)
1:1Constructor CRM workflows do not have a direct HighLevel equivalent because each platform's automation logic is structured differently. We export your Constructor workflow definitions as a reference document. A HighLevel-certified specialist (or your team) then rebuilds each workflow in HighLevel's Workflow Builder using that document as a blueprint.

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.
Constructor gotchas
Reporting and filter limitations make pre-migration data inventory harder
Estimating templates and take-offs carry business logic, not just data
KeyPay payroll data lives in a connected but separate system
Uptime variability requires staged migration windows
Custom integrations (Salesforce, ClickHomes, OCR, ELO) need separate scoping
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 Constructor CRM data model and define HighLevel schema
FlitStack connects to Constructor CRM via scoped API access to enumerate all objects, fields, custom fields, pipelines, and stage configurations. We produce a schema plan for HighLevel that lists every custom field to pre-create, every pipeline to set up, and every object-to-object mapping. You review and approve the plan before any data is touched. If you plan to use HighLevel sub-accounts, this step also defines how records will be distributed across them.
Create custom fields and pipelines in HighLevel
Your HighLevel admin creates the custom fields (or approves FlitStack's API calls to create them) and sets up the pipelines and stages that correspond to your Constructor configuration. FlitStack provides a detailed step-by-step checklist and field creation guide so nothing is missed during the setup process. Pipelines are created in HighLevel first because deal-stage mapping references them directly, and all custom field definitions must be finalized before the migration run begins.
Resolve owners and contacts by email match
Before any records are written to HighLevel, FlitStack resolves Constructor owner email addresses against existing HighLevel user accounts through an email matching process. Any owner in Constructor without a matching HighLevel user appears in a pre-migration report with clear identification of unresolved owners. Your team either creates the missing HighLevel user accounts or assigns those records to a designated fallback owner during this resolution phase. No record migrates without a resolved owner to maintain proper accountability and assignment tracking.
Run sample migration with field-level diff
A representative slice of records, typically 100 to 500 contacts, companies, deals, and activities, migrates first to validate the migration logic before committing the full dataset. FlitStack generates a comprehensive field-level diff showing every field value in Constructor alongside the corresponding value that landed in HighLevel, allowing you to verify stage mapping accuracy, tag migration completeness, custom field value integrity, and owner resolution correctness. Your approval of the sample migration triggers the full data migration run.
Execute full migration with delta-pickup window
Full data migration runs against HighLevel's API with rate-limit-aware batching. After the primary run completes, a delta-pickup window (typically 24–48 hours) captures any records created or modified in Constructor during the cutover period. FlitStack's audit log records every operation, and one-click rollback is available if reconciliation against your Constructor export reveals any discrepancies before you close out your Constructor account.
