Overview

What this migration involves

Star CRM and Nutshell share a small-business CRM orientation with a similar Contacts-Companies-Deals data model, but Star CRM does not publish API documentation or a developer portal. We work around this by performing live API discovery during scoping, exporting a sample record set to infer actual field names and types, and building all field mappings from that observed data. Nutshell's Import2 tool handles CSV-based import of companies, people, and deals, which works cleanly for standard record types. Activity history (calls, emails, notes) presents the most complex challenge because Import2's CSV format does not natively preserve activity-to-contact relationship links, so we use a staging approach to re-associate activities with their parent records after initial load. Workflows, sequences, and automations do not migrate as code; we deliver a written inventory for the customer admin to rebuild in Nutshell.

Field-level fidelity

Every standard and custom field arrives verified.

Schema-aware mapping

AI proposes the map; you confirm before any record moves.

Relationships preserved

Parent–child, lookups, and ownership stay linked.

Full activity history

Calls, emails, meetings — with original timestamps.

Attachments & notes

Documents, uploads, and inline notes move with the record.

Why teams make this switch

Two sides of the same decision

Leaving

Star CRM

What's pushing teams away

  • Limited documentation and public API availability make it difficult to integrate Star CRM with other business tools or build custom workflows.
  • Small teams may eventually need advanced automation, AI features, or scalability that Star CRM does not provide at higher tiers.
  • G2 notes there are not enough public reviews to assess the platform thoroughly, which raises questions about long-term viability and community support.

Choosing

Nutshell logo

Nutshell

What's pulling them in

  • Lowest cost entry point among mid-market CRMs—Foundation plan starts at $13/user/month, making it accessible for teams validating CRM fit before committing.
  • Integrated sales automation and email sequencing on Pro plans without requiring a separate email marketing platform, per verified Capterra reviews.
  • Consistently praised for intuitive interface and fast onboarding, with case studies reporting 100% team adoption rates within initial deployment periods.
  • Strong customer support responsiveness cited across G2 reviews, with dedicated support tiers available on Enterprise plans.
  • Native integrations with WhatsApp, Facebook Messenger, Instagram, and Slack reduce reliance on third-party middleware for common communication channels.

Object mapping

How Star CRM objects map to Nutshell

Each row shows how a Star 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.

Star CRM

Contacts

maps to

Nutshell

People

1:1
Fully supported

Star CRM Contact records map directly to Nutshell People. We infer the Contact field schema during API discovery by exporting a sample of 10-20 records and extracting all present field names and types. Standard fields (name, email, phone, address) map 1:1. Custom contact properties are documented during discovery, and matching custom fields are pre-created in Nutshell via Import2 configuration before the full import. Email address is used as the dedupe key during import.

Star CRM

Companies

maps to

Nutshell

Companies

1:1
Fully supported

Star CRM Company records map directly to Nutshell Companies. Company names and addresses migrate 1:1. We use company name as the dedupe key for Company records and as the lookup resolution key for linking child People records to their parent Company. If the source Company data uses a domain field, that maps to the Nutshell Company website field.

Star CRM

Deals

maps to

Nutshell

Deals

1:1
Mapping required

Star CRM Deal records map to Nutshell Deals. Deal name, value (amount), stage, owner, and created/modified timestamps migrate directly. Pipeline stage names from Star CRM may not match Nutshell's default stage values, so we map each observed stage name to a Nutshell stage value during the scoping call. The Deal-to-Contact association uses the linked Contact ID from Star CRM, resolved against the migrated Contact's new Nutshell ID.

Star CRM

Activities (calls, emails, meetings)

maps to

Nutshell

Activities (Tasks and Events)

lossy
Fully supported

Star CRM Activity records (calls, emails, meetings, tasks, notes) map to Nutshell Activities. Date formats and activity types vary between systems and are normalized during the transform phase. Note content migrates as Activity notes. Activity-to-Contact linkage requires post-load re-association because Import2's CSV format does not natively preserve relationship links; we build a staging table linking each activity to its original Contact ID, then update Nutshell Activity records to point to the migrated Contact after initial load.

Star CRM

Users (Owners)

maps to

Nutshell

Users

1:1
Fully supported

Star CRM User records containing name, email, and role assignment map to Nutshell Users. User assignment on Deals and Activities maps to the Nutshell owner field. We match Users by email address. Any Star CRM Owner without a matching Nutshell User is flagged for the customer admin to provision before the migration runs. Inactive users are flagged separately for the customer to decide whether they are included.

Star CRM

Tags

maps to

Nutshell

Tags or Custom Fields

lossy
Mapping required

Tags on Star CRM Contacts or Deals transfer as label fields in Nutshell. Multi-select tags may split into separate fields depending on whether the destination field is a single-select or multi-select type. We preserve all tag names and apply them consistently during import. The customer chooses the tag handling strategy during scoping.

Star CRM

Pipelines

maps to

Nutshell

Deal Pipelines

lossy
Mapping required

Star CRM pipeline stages map to Nutshell deal pipeline stages. We configure Nutshell pipeline stages before migration to match the source stage names and probabilities as closely as possible. Each Star CRM stage value maps to a corresponding Nutshell stage value, and stage-specific notes or custom fields migrate as custom Activity fields.

Star CRM

Attachments

maps to

Nutshell

Files

1:1
Mapping required

Star CRM attachments export as individual files per record, with no structured archive or parent-record manifest in the export. We download all attachment files, build a manifest associating each file with its parent record ID or name, and upload files to Nutshell after the parent records are created. The re-association step uses the manifest to link each file to the correct Nutshell record. This step adds time proportional to attachment volume.

Pair-specific challenges

  • No published API spec requires live schema inference

    Star CRM does not publish API documentation or a public developer portal, so we cannot programmatically enumerate the schema or verify field names before migration begins. We handle this by performing live API discovery calls during scoping, exporting a sample record set to infer the actual field structure, and building all field mappings from that observed data rather than documentation that does not exist. This discovery step adds two to three days to the project timeline and must complete before the migration mapping is finalized.

  • No confirmed bulk export endpoint extends extraction time

    The research did not surface a bulk data export or batch API endpoint for Star CRM. If the platform requires record-by-record export through the UI or a single-record API, databases with tens of thousands of records will take significantly longer to extract. We work around this by automating repeated API calls with pagination where available, running exports during off-peak hours, and chunking the extraction into batches to avoid session timeouts or throttling.

  • Activity-to-contact linkage does not survive CSV import

    Nutshell's Import2 tool uses CSV-based import, which does not natively support preserving activity-to-contact relationship links in a single-pass load. Activity records can be imported with the correct timestamps and content, but the association to the parent Contact or Deal requires a post-load update step. We stage the activity-contact mapping during extraction and re-link all activities after the parent records exist in Nutshell. For large engagement histories (over 50,000 records), this step adds measurable time and requires careful reconciliation against the original Star CRM timeline.

  • Attachment export produces individual files with no manifest

    Star CRM exports attachments as separate files per record without a structured archive or parent-record manifest. A contact with five email threads and two documents becomes five separate files plus two separate files, all named by the system without obvious parent-record identifiers. We download all files, build a manifest linking each file to its parent record ID or name, and re-associate them in Nutshell during upload. This step adds time proportional to attachment volume and must be planned during scoping for projects with heavy attachment use.

  • Data quality issues from Star CRM multiply in the new system

    Star CRM is typically used by small teams without dedicated data governance processes, which means duplicate contacts, inconsistent address formats, missing phone numbers, and incomplete company records are common. Dirty data does not stay contained during migration — it spreads through Nutshell and can break automation and reporting. We audit the source data before migration, run deduplication by email and company name, normalize address formats, and flag records with missing required fields for the customer to address before the migration runs.

Migration approach

Six steps for a successful Star CRM to Nutshell data migration

  1. API discovery and scoping call

    We perform live API discovery calls against Star CRM to infer the actual field structure across all active record types. We export a sample of 10-20 records per object (Contacts, Companies, Deals, Activities) and document every observed field name, type, and value pattern. During the scoping call, we review the discovered schema with the customer, identify custom fields, pipeline stages, user accounts, and any non-standard record types, and confirm the target Nutshell configuration. This step is required before any mapping work begins because Star CRM provides no public schema reference.

  2. Data quality audit and cleansing

    We run a data quality audit against the Star CRM export to identify duplicate records (deduped by email), incomplete records (missing required fields), inconsistent address formats, and stale Deals that should be archived rather than migrated. We present a cleansing report to the customer and perform agreed-upon deduplication and normalization before the migration runs. Pre-migration data cleansing reduces migration time and prevents dirty data from spreading into Nutshell, where it is harder to fix after go-live.

  3. Nutshell custom field and pipeline configuration

    We pre-configure Nutshell before any data loads. This includes creating any custom fields discovered in Star CRM (with field types matched to Nutshell's supported types: text, long text, currency, date), configuring deal pipeline stages to match the Star CRM stage names and probabilities, and setting up the Nutshell user accounts that will receive migrated records. Import2 configuration is set up during this phase so that the migration is ready to run once data extraction is complete.

  4. Sample migration and reconciliation

    We run a sample migration using a subset of the production data volume (typically 100-500 records per object) into the customer's Nutshell environment to validate the field mappings and reconciliation logic. The customer reviews the sample import in Nutshell, spot-checks 20-30 records against the Star CRM source, and signs off before the full production migration begins. Any mapping corrections happen at this stage. This step prevents field mapping errors from reaching production data.

  5. Production migration in dependency order

    We run the full production migration in record-dependency order: Companies first (independent records), then People (with Company lookup resolved), then Deals (with People and Company lookups resolved), then Activities (with post-load re-association to parent People or Deals), then Attachments (with file-to-record re-association via manifest). Each phase emits a row-count reconciliation report. We freeze Star CRM writes during the cutover window and run a final delta migration of any records modified during the migration run.

  6. Validation, cutover handoff, and automation inventory

    We validate the production migration by matching record counts, spot-checking 50 random records against Star CRM, and confirming activity linkage in Nutshell. We deliver a written handoff document that includes the full data inventory (records migrated, records skipped with reasons), a list of custom fields created in Nutshell, a written inventory of all Star CRM automations or workflows that require rebuilding in Nutshell, and a recommended Nutshell automation approach for each item. We do not rebuild automations as part of the standard migration scope.

Most migrations land between two and four weeks for accounts under 5,000 Contacts, 2,000 Companies, and 1,000 Deals with clean data and no custom fields. Migrations exceeding these thresholds, with multiple custom fields or large activity histories, move to four to eight weeks because of the API discovery work, field inference process, data cleansing scope, and post-load activity re-linking. Timeline also depends on Star CRM's export response times, which we assess during the discovery phase.
