Overview
Moving from Delta Sales CRM to Nutshell is a structural migration constrained by one hard fact: Delta Sales CRM has no documented public REST API, GraphQL endpoint, or developer portal. All evidence points to CSV-based export as the only structured extraction path, which means migration tooling must build a custom export pipeline from the web application's data layer. We handle this, transform the CSV into Nutshell's Import2-compatible format, and chunk large activity histories by rep and date range to avoid timeout. Nutshell's standard People, Companies, Leads, and Opportunities objects cover the core CRM record types. Delta's unique field-force objects (Beat Plans, Attendance, GPS visit logs) have no direct Nutshell equivalent; Beat Plans migrate as Custom Objects with a documented schema, while Attendance and GPS metadata are flagged as out-of-scope during discovery. Workflows, automations, and forms do not migrate and are delivered as a written rebuild inventory for the customer's admin.
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 Delta Sales CRM object lands in Nutshell, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Delta Sales CRM
Contact
Nutshell
Person (People)
1:1Delta Contact records map directly to Nutshell Person records. We preserve the full name, phone, email, address, and company linkage. Delta's lifecycle or status property maps to a custom Nutshell Person field if the customer requires the historical segmentation; otherwise contacts land with default Nutshell status. Owner assignment resolves by email match against Nutshell Users.
Delta Sales CRM
Company
Nutshell
Company
1:1Delta Company records map 1:1 to Nutshell Company records. The company-contact relationship is preserved as a link on the Nutshell Person record. Company name, address, domain, and any custom fields migrate directly. We create the Company record before Person import so the lookup is satisfied at insert time.
Delta Sales CRM
Lead
Nutshell
Lead
1:1Delta Lead records with unqualified status map to Nutshell Lead. Lead status, source, and owner assignment migrate directly. Any Delta Leads that are already sales-qualified and attached to a Company may be candidates for pre-conversion to Nutshell Person/Account during migration; the customer decides the strategy during scoping based on their pipeline definition.
Delta Sales CRM
Deal
Nutshell
Opportunity
1:1Delta Deal records map to Nutshell Opportunity. Deal amount, probability, close date, and owner assignment migrate directly. Delta pipeline stage names map to Nutshell pipeline stage values that we configure during the schema design phase. The deal-company and deal-contact linkages migrate as Opportunity-Company and Opportunity-Person lookups.
Delta Sales CRM
Pipeline
Nutshell
Pipeline
lossyDelta's multiple pipeline configurations (stage names, stage order, stage probabilities) are extracted as configuration metadata and rebuilt as Nutshell Pipelines. On Nutshell Foundation (1 pipeline) the stages map into a single pipeline; Growth and above support multiple pipelines at no extra cost. We map stage probabilities to Nutshell's stage weighting for accurate forecast reporting.
Delta Sales CRM
Activity (Tasks, Meetings, Calls, Notes)
Nutshell
Activity (Tasks, Events, Notes)
1:manyDelta Activities (tasks, meetings, calls, notes, reminders) are distributed to the appropriate Nutshell Activity type: tasks and calls map to Nutshell Task with TaskSubtype preserved, meetings map to Nutshell Event, and notes map to Nutshell Note. Date ordering is preserved by setting the original timestamp. Assignee mapping resolves by email match against Nutshell Users. Large activity histories are chunked by rep and date range to avoid timeout during CSV import.
Delta Sales CRM
Product
Nutshell
Product
1:1Delta Products (name, price, unit, description) map to Nutshell Products. Products are migrated before Deals so that the product linkage on Nutshell Opportunities is satisfied at import time. SKU and pricing fields migrate directly to Nutshell's product name and price fields.
Delta Sales CRM
Beat Plan (Route Plan)
Nutshell
Custom Object
lossyDelta Beat Plans assign route sequences to field reps and are a unique feature with no direct Nutshell equivalent. We export Beat Plan records as structured data (route name, assigned rep, stop sequence, customer visit assignments, and schedule) and recreate them as a Nutshell Custom Object with fields for route_name, assigned_rep, stop_order, customer_name, visit_date, and visit_notes. Nutshell's 10-Custom Object limit is checked during scoping; if the customer has fewer than 10 custom object types across all Delta custom objects, the Beat Plan conversion fits. The route-sequence visualization logic is not migratable and requires a rebuild in Nutshell or a third-party route-planning tool.

Migration approach
Discovery and data audit
We audit the source Delta Sales CRM account across all active objects, record counts, custom field definitions, pipeline configurations, and activity volume. We confirm the absence of any API access and design the CSV extraction pipeline accordingly. We check device sync status across all field reps and require a 24-hour online window before migration begins. The discovery output is a written migration scope including object inventory, Beat Plan count, attachment volume, and a recommendation on which Nutshell tier (Foundation, Growth, Pro, Business, or Enterprise) the customer needs based on their data model complexity.
Schema mapping and Nutshell configuration
We map Delta objects to their Nutshell equivalents: Contacts to People, Companies to Companies, Leads to Leads, Deals to Opportunities, Activities to Tasks and Events, and Products to Products. Delta's pipeline configurations are recreated as Nutshell Pipelines with stage names and probability weights carried over. Beat Plans are designed as a Nutshell Custom Object with fields for route_name, assigned_rep, stop_order, customer, visit_date, and notes. We pre-create all custom fields in Nutshell before any data import begins to avoid import errors on required fields.
Test migration and reconciliation
We run a full migration into the customer's Nutshell trial or sandbox environment using production-like data volume. We reconcile record counts between Delta and Nutshell for every object (People, Companies, Leads, Opportunities, Activities). The customer's admin spot-checks 25-50 records against the Delta source and validates the Beat Plan custom object structure. Any field mapping corrections, custom field additions, or pipeline stage adjustments happen here. No production data moves until the test migration is signed off.
Production migration in dependency order
We run production migration in the correct order: Nutshell Users (validated against the User provisioning list), Companies, People (with CompanyId resolved), Leads, Opportunities (with PersonId, CompanyId, and OwnerId resolved), Products, Custom Object (Beat Plans), Activities (Tasks and Events chunked by rep and date range). Each phase emits a row-count reconciliation report before the next phase begins. We use Nutshell's native Import2 integration for standard objects and the REST API (if Enterprise tier) or CSV upload for custom objects.
Cutover, validation, and handoff
We freeze Delta Sales CRM writes during the cutover window and run a final delta migration of any records created or modified during the migration. We enable Nutshell as the system of record and deliver a migration report including record counts per object, any records that could not be imported with reason codes, and a written inventory of Beat Plans as a Custom Object schema. We do not migrate Delta Workflows, automations, or forms as code; those are delivered as a written rebuild inventory for the customer's admin to reconstruct in Nutshell. We offer a one-week post-migration hypercare window for reconciliation issues raised by the sales team.
