Overview
Allegory CRM stores contacts, companies, deals, leads, tasks, notes, and custom fields in a relational model that varies from Nutshell's People-Accounts-Deals structure. We map Allegory contacts to Nutshell People, Allegory companies to Nutshell Accounts, and Allegory deals to Nutshell Deals. Leads are preserved as Nutshell Leads with a custom source field. Tasks and notes map to Nutshell Activities. Custom fields on People and Accounts migrate as Nutshell custom fields — the plan lists each one before the migration runs. Workflows, automations, email templates, and reporting configurations do not migrate; FlitStack exports definitions as reference documents for your Nutshell admin to rebuild. The migration uses Nutshell's JSON-RPC API over HTTPS with Basic authentication, respecting rate limits on find operations so the migration stays within service thresholds. Owner resolution works by email match against Nutshell users, and records without a matched owner land with a designated fallback owner flagged before the run commits.
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 Allegory 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.
Allegory
Contact
Nutshell
Person
1:1Allegory contacts map directly to Nutshell People. Nutshell People store name, email, phone, address, and custom fields. A primary company association migrates as the AccountId link; contacts without a company land in Nutshell without an account association and can be linked manually post-migration.
Allegory
Company
Nutshell
Account
1:1Allegory companies map to Nutshell Accounts. Account stores company name, website, industry, employee count, revenue, and custom fields. Nutshell Accounts support parent-child hierarchies using a parent_account_id field — we map Allegory's parent company link accordingly. We also preserve the original Allegory company ID as a custom field for cross-referencing and audit trails.
Allegory
Deal
Nutshell
Deal
1:1Allegory deals map to Nutshell Deals with full pipeline stage mapping. Each Allegory deal stage maps to a corresponding Nutshell deal stage — we build the stage mapping table during planning. Deal amount, close date, owner, and custom fields migrate directly. Nutshell's deal list supports list, map, chart, and board views.
Allegory
Lead
Nutshell
Lead
1:1Allegory leads map 1:1 to Nutshell Leads. Lead status, source, owner, and custom fields migrate. Leads in Allegory that are already converted require a flag in the Nutshell Lead indicating the conversion status and related Person/Deal references. If a lead is attached to a converted Person, we store the original Allegory contact ID on the Nutshell Lead record for reconciliation.
Allegory
Task
Nutshell
Activity
1:1Allegory tasks map to Nutshell Activities with Type='Task'. Original due date, description, owner, and status (completed/pending) migrate. Completed tasks preserve the completion timestamp; open tasks preserve the due date. If Allegory tasks have a priority field, we map it to a custom Nutshell text field so managers can sort by priority in reports.
Allegory
Call
Nutshell
Activity
1:1Allegory call logs map to Nutshell Activities with Type='Call'. Duration, outcome (answered, voicemail, no answer), notes, and timestamp migrate. Call owner resolves by email match to a Nutshell user. If Allegory records include a call disposition code, we store it as a custom text field on the Nutshell Activity for downstream reporting.
Allegory
Nutshell
Activity
1:1Allegory email logs migrate as Nutshell Activities with Type='Email'. Subject, body, direction (sent/received), timestamp, and owner migrate. Email thread linking depends on Allegory's thread ID — if present, we surface it as a custom field in Nutshell for manual thread reconstruction.
Allegory
Meeting
Nutshell
Activity
1:1Allegory meeting records migrate to Nutshell Activities with Type='Meeting'. Start time, end time, location, attendees (as notes), and owner migrate. Recurring meetings from Allegory expand into individual Nutshell Activity records with a recurrence reference field. If the Allegory meeting includes an organizer field, we map it to the Nutshell Activity owner to preserve attribution.
Allegory
Note
Nutshell
Activity
1:1Allegory notes on contacts or companies migrate as Nutshell Activities with Type='Note'. Note body and timestamp migrate. Rich-text formatting is preserved where Allegory supports it — plain text where it does not. If the note contains any @mentions of other users, we preserve the mention text as a custom field for follow-up.
Allegory
Attachment / File
Nutshell
File Attachment
1:1File attachments on Allegory contacts, companies, or deals re-upload to Nutshell as file attachments on the corresponding record. File size limits apply per Nutshell's attachment handling — we flag any files exceeding Nutshell's supported size before the run. We also log the original Allegory file ID in a custom field to assist with any post-migration file audit.
Allegory
Custom Object
Nutshell
Custom Object
1:1Allegory custom objects map 1:1 to Nutshell custom objects if they exist in the Nutshell account. Custom object associations using N:N relationships in Allegory need junction objects in Nutshell — we document this in the migration plan and let you decide whether to rebuild the association logic.
Allegory
User / Owner
Nutshell
User
1:1Allegory users and deal owners resolve by email match against Nutshell users. Unmatched owners are flagged before migration — your team either creates the Nutshell user first or assigns their records to a designated fallback user. No record lands without a valid Nutshell owner.

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.
Allegory gotchas
Acquisition status may mean migrated data already exists in Integreon
No public API means manual export and file-based migration
Inactive website and product status limits vendor coordination
Nutshell gotchas
Contact tier limits enforced on import
No bulk API endpoint requires paginated extraction
Email sequences not exportable via API
Foundation plan disables key sales features
Pair-specific challenges
Migration approach
Audit Allegory data and plan the Nutshell schema
FlitStack extracts a full export from Allegory covering contacts, companies, deals, leads, tasks, calls, emails, meetings, notes, and custom field definitions. We profile the data for duplicates, missing required fields, and record counts per object. Simultaneously, we inventory the target Nutshell account — plan tier, existing custom fields, pipeline stages, and user list. The output is a field-level mapping document showing every Allegory field, its Nutshell destination, mapping type (direct, value-map, custom field), and any fields that cannot migrate without a plan upgrade or manual rebuild.
Create Nutshell custom fields and configure pipeline stages
Before data moves, your Nutshell admin (or FlitStack acting as admin) creates any missing custom fields on People, Accounts, Leads, and Deals. This includes custom fields for original Allegory timestamps, deal probability, and Allegory-specific pick-list values that don't map to Nutshell defaults. If Allegory has multiple deal pipelines, we configure corresponding Nutshell pipelines. We also configure the Nutshell API key with impersonation enabled so activity owners resolve correctly. This step is a dry-run with the Nutshell admin to confirm every planned custom field is within your plan's limits.
Resolve owners and validate user accounts
Allegory owner and user IDs are resolved against Nutshell users by email address. Any Allegory owner whose email does not match an existing Nutshell user is flagged with a fallback owner assignment. Your team decides whether to create Nutshell accounts for unmatched owners before migration or consolidate their records under a designated admin account. No record is written without a confirmed Nutshell owner ID.
Run sample migration with field-level diff
A representative slice of Allegory data — typically 200–500 records covering contacts, companies, deals, leads, and a mix of activity types — migrates into Nutshell first. We generate a field-level diff showing source value, destination value, mapping type applied, and any transformations. You review the diff and confirm the mapping before the full run. This step catches missing custom fields, incorrect value mappings, and owner resolution gaps before any bulk data moves.
Execute full migration with delta pickup window
The full migration runs against the Nutshell API, following the Companies → People → Deals → Leads → Activities sequence to satisfy foreign-key dependencies. Nutshell's rate-limit behavior on find requests is handled by our migration script with exponential backoff. A delta-pickup window (24–48 hours after the initial run) captures any Allegory records modified during the cutover window. An audit log records every operation; one-click rollback reverts the Nutshell account to its pre-migration state if reconciliation fails. Post-migration, we deliver a reconciliation report comparing Allegory record counts against Nutshell record counts per object.
