Overview
BoomTown bundles CRM, IDX website hosting, and lead-generation services under a single opaque contract. Nutshell is a dedicated B2B sales CRM with per-user pricing and an open JSON-RPC API. The migration maps BoomTown's core entities (People, Companies, Leads, Deals, Activities, and any custom fields) to Nutshell's equivalent objects. We pull records through BoomTown's API in paginated batches, apply field-level mapping, and load into Nutshell using its JSON-RPC API with rate-limit awareness. Standard BoomTown fields like first name, last name, email, phone, and company name map directly to Nutshell People fields. Pipeline stages and deal values map to Nutshell Deal stages with probability re-application on the Nutshell side. What BoomTown stores as lead status and lead score become custom fields on Nutshell Leads, since Nutshell has no native equivalent. BoomTown's real estate drip campaigns and lead-routing workflows have no functional analogue in Nutshell — we export your workflow definitions as a reference JSON so your admin can rebuild them in Nutshell's automation tools. The migration runs in staged passes: an initial audit export, a test migration against a sample slice, then a full run with a 24–48 hour delta-pickup window for any in-flight changes during cutover. A field-level diff report and audit log ship with every migration so your team can verify mapping fidelity before the destination goes live.
Every standard and custom field arrives verified.

Object mapping
Each row shows how a BoomTown 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.
BoomTown
Person
Nutshell
Person
1:1BoomTown People map 1:1 to Nutshell People. All standard person fields (name, email, phone, address) transfer directly. BoomTown's owner assignment resolves to a Nutshell user by email match. Records with no assigned owner land under a migration-system fallback owner. During migration, any missing owner is mapped to a designated system account, ensuring all records have an accountable user.
BoomTown
Company
Nutshell
Company
1:1BoomTown Companies map to Nutshell Companies. Company name, domain, address, and industry fields transfer directly. Parent-company hierarchies in BoomTown map to Nutshell's parent-company field. Multi-contact companies in BoomTown attach all associated People to the same Nutshell Company record. If multiple companies share the same domain, we consolidate them into a single Nutshell Company to avoid duplicate entries.
BoomTown
Lead
Nutshell
Lead
1:1BoomTown Leads map directly to Nutshell Leads. The Lead status value (Active, Contacted, Qualified, etc.) transfers as-is. If BoomTown uses a custom status pick-list, those values are preserved as custom field values in Nutshell and your admin applies the correct Nutshell status labels after migration.
BoomTown
Deal
Nutshell
Deal
1:1BoomTown Deals map to Nutshell Deals. Deal name, value, close date, and associated Person and Company all transfer. The BoomTown pipeline stage name maps to a Nutshell Deal stage — if BoomTown uses multiple pipelines, all stage names from all pipelines are consolidated into Nutshell's single pipeline stages by your admin-defined mapping table.
BoomTown
Activity (Call)
Nutshell
Task
1:1BoomTown call logs migrate as Nutshell Tasks with Type set to 'Call'. Original call duration, timestamp, owner, and linked Person or Deal are preserved. The call subject defaults to 'Call with [Person Name]' if BoomTown stored no subject. If the Person name is unavailable, the subject falls back to a generic 'Call logged' placeholder, ensuring every task has a title.
BoomTown
Activity (Email)
Nutshell
Task
1:1BoomTown email logs become Nutshell Tasks with Type set to 'Email'. The email subject, body text, and timestamp transfer. Linked Person and Deal associations are preserved through Nutshell's task-entity relationship model. If the email lacks a subject line, a default placeholder 'Email from BoomTown' is used to ensure the Nutshell task has a readable title.
BoomTown
Activity (Note)
Nutshell
Note
1:1BoomTown notes migrate as Nutshell Notes attached to the corresponding Person, Company, Lead, or Deal. Rich-text formatting in BoomTown notes is converted to plain text in Nutshell. Note create date and owner are preserved as metadata on the Nutshell Note record.
BoomTown
Lead Status
Nutshell
Custom Field on Lead
1:1BoomTown's native lead status values (Active, Converted, Dead, etc.) have no exact Nutshell equivalent. We create a custom field on the Nutshell Lead object called 'BoomTown Lead Status' to preserve the source value. The field is a pick-list matching BoomTown's exact value set. Your Nutshell admin maps these to Nutshell's native status after migration.
BoomTown
Lead Score
Nutshell
Custom Field on Lead
1:1BoomTown lead scoring values transfer as a custom numeric field called 'BoomTown Lead Score' on the Nutshell Lead object. The score is preserved for reporting and segmentation reference. Nutshell does not compute lead scores natively — if you rely on this for routing, your admin rebuilds the scoring logic in Nutshell or a connected tool.
BoomTown
Custom Field
Nutshell
Custom Field
1:1Any BoomTown custom field on Person, Company, Lead, or Deal creates a corresponding custom field in Nutshell. Field type is inferred from BoomTown's API field metadata: text maps to Nutshell text, number maps to Nutshell number, date maps to Nutshell date. Nutshell's custom field creation UI requires manual setup or API calls — we include the field creation plan in the migration package.
BoomTown
User / Owner
Nutshell
User
1:1BoomTown user records are matched to Nutshell users by email address. Matched users receive ownership of their records in Nutshell. Unmatched BoomTown users — those with no corresponding Nutshell account — are flagged before migration. You either provision their Nutshell seat first or reassign their records to a designated fallback owner.
BoomTown
Drip Campaign / Automation
Nutshell
No Equivalent
1:1BoomTown drip campaigns and automated follow-up sequences do not migrate. These are platform-configured logic with no schema-level export. We deliver a JSON export of your BoomTown workflow definitions — trigger conditions, step sequences, delay rules — so your Nutshell admin has a rebuild reference. Nutshell Pro+ supports personal email sequences but the logic is manual and step-based, not a campaign builder.

Migration approach
Audit BoomTown data inventory and map field schema
FlitStack AI connects to your BoomTown account via API using a read-only integration token. We pull a full inventory of People, Companies, Leads, Deals, Activities, and all custom field definitions — including field types, pick-list values, and parent-child relationships. This inventory feeds the field mapping plan. We generate a schema-diff report showing every BoomTown field with a direct Nutshell equivalent, every field requiring a custom Nutshell field, and every BoomTown object with no Nutshell counterpart. Your team reviews the plan before any data moves.
Create Nutshell custom fields and prepare the target schema
Before records are loaded, FlitStack AI creates the custom fields identified in the audit phase on the appropriate Nutshell objects (Person, Company, Lead, Deal). For pick-list fields, we pre-populate the option sets with BoomTown's exact values. If multiple BoomTown pipelines need to collapse into Nutshell's single pipeline, we create a 'Deal Type' custom field and build the stage mapping table at this point. Owner resolution happens here: BoomTown user email addresses are matched against Nutshell user emails, and unmatched users are flagged for your team to either provision or reassign.
Run sample migration and field-level diff
A representative slice of 100–250 records — spanning People across different lead statuses, Companies with varying team sizes, Deals in multiple stages, and Activities of each type — is migrated to Nutshell first. We generate a field-level diff comparing source values against destination values for every mapped field. You review the diff to confirm that BoomTown pipeline stage names map correctly to Nutshell stages, that custom field values landed in the right place, and that Person-to-Company associations resolved as expected. No records are deleted or overwritten during the sample run.
Execute full migration with delta-pickup window
After sample approval, the full migration runs in sequenced passes: Companies first (since People and Deals reference them), then People and Leads, then Deals with their linked Person and Company associations, then Activities. The Nutshell JSON-RPC API receives records in dependency order to satisfy foreign-key constraints. During the full migration window, your team continues working in BoomTown — the migration uses read-only API access. A delta-pickup pass runs 24–48 hours after the initial load to capture any records created or updated in BoomTown after the extraction timestamp. An audit log records every insert and update operation.
Deliver reconciliation report and post-migration support
FlitStack AI generates a reconciliation report showing record counts by object, any records that failed to migrate with error reason codes, and a record-level comparison of the delta pass. The report includes the workflow export JSON for your admin to use as a rebuild reference in Nutshell. If reconciliation reveals gaps, one-click rollback reverts the Nutshell instance to its pre-migration state so your team can correct the mapping and re-run. Post-migration support is available for 5 business days after delivery.
