Migrate from Black Ice CRM to HighLevel

Discovery and export method confirmation

We audit the active Black Ice CRM modules by reviewing the customer's current subscription or by accessing the application to list active features. We identify all modules in use (Leads, Accounts, Quotes, Orders, Invoices, Products, Stock Management) and the approximate record counts per module. We simultaneously confirm the available export method: application-built CSV export, database backup, or direct SQL access. If only CSV is available, we assess whether the flat structure captures the required relationships. We deliver a written scoping document that lists all active modules, record volumes, identified custom fields, and the confirmed export method before work begins.

Pre-migration field audit and schema design

We request a sample export from Black Ice CRM covering all active modules to document the actual field names, field types, and any custom fields present. We compare this against the standard Black Ice CRM object schema and flag any deployment-specific custom fields. We then design the GoHighLevel destination schema: we create custom fields on GoHighLevel native objects (Contact, Company, Opportunity, Product, Custom Objects) to match the Black Ice custom fields, and we configure GoHighLevel Pipelines and stages to mirror the Black Ice potential tracking stages. The field mapping spreadsheet is shared with the customer for review and sign-off before data extraction begins.

Data extraction and transformation

We extract data from Black Ice CRM using the confirmed method (application export or database export). We run the export through a transformation layer that applies the field mapping, converts date formats, normalises country and address formats to GoHighLevel's expected structure, and splits multi-value fields (such as multiple phone numbers) into separate GoHighLevel custom fields. We generate a reconciliation report comparing extracted record counts against the scoping estimate. Any records with missing required fields (such as Contacts with no email) are flagged in a data quality report for the customer to review and resolve before import.

Parent record import first

We import data in record-dependency order: Companies first (from Black Ice Accounts), then Contacts (with Company lookup resolved), then Leads, then Products, then Opportunities. This ordering ensures that every Contact has a valid Company reference and every Opportunity has a valid Contact and Company. If Black Ice CRM Quotes are being merged into Opportunities, the Quote header data is transformed before the related Opportunities are imported. Products are imported before Opportunities so that line items can reference valid product IDs. Each phase emits a row-count reconciliation report before the next phase begins.

Child record and historical data import

After parent records are stable, we import child records in dependency order: Order line items against Opportunities, Invoice records against Accounts, and any stock quantity or reorder threshold data against Products. If the customer has a large volume of historical Orders or Invoices (over 2,000 records), we chunk the import into batches of 500 records with a validation pause between batches. GoHighLevel's API rate limits are respected with exponential backoff and retry logic. We do not import picking list documents or operational outputs that are application-generated rather than primary data records.

Cutover, validation, and workflow rebuild handoff

We freeze Black Ice CRM writes during the cutover window, run a final delta migration of any records modified since the initial export, then enable GoHighLevel as the system of record. We deliver a reconciliation report comparing GoHighLevel record counts against the Black Ice source counts, with a record-level spot check of 20-30 records per object type. We deliver the Workflow and automation inventory document to the customer's admin team with GoHighLevel Workflow Builder equivalents. We support a three-day hypercare window to resolve import issues raised during initial GoHighLevel usage. We do not rebuild Black Ice CRM workflows or automations inside the migration scope; that work is a separate engagement.
