Overview
LeadManaging organizes multifamily leasing data around a flat lead model: contacts, companies, and deals share a simpler schema than most CRMs. Nutshell structures its CRM around three distinct objects — People, Companies, and Leads — with custom fields for extensibility and separate pipeline configuration. The migration from LeadManaging to Nutshell carries your contact records, company records, deal/pipeline data, and activity history into Nutshell's object graph, while creating custom fields for LeadManaging-specific properties that have no native Nutshell equivalent. FlitStack AI sequences the migration to preserve foreign-key relationships: companies land first, then people with their primary company link, then leads and deals that reference those companies and people. Custom properties from LeadManaging migrate as Nutshell custom fields on the appropriate object — People, Company, or Lead — so your team retains visibility into property-level context without manual re-entry. Activity records (calls, emails, meetings, notes) transfer with original timestamps and owner attribution. The migration uses Nutshell's JSON-RPC API with scoped read access to the source system, keeping your LeadManaging account fully operational during cutover. A 24–48 hour delta pickup window captures in-flight changes made during the transition.
Every standard and custom field arrives verified.

Object mapping
Each row shows how a LeadManaging 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.
LeadManaging
Lead / Contact record
Nutshell
Person (People object)
1:1LeadManaging's person data maps directly to Nutshell's Person object. Name, email, phone, job title, and address fields transfer as-is. The person's primary company association resolves to a Nutshell Company record that must be created first to satisfy the foreign-key relationship.
LeadManaging
Lead / Company name
Nutshell
Company (Account)
1:1When LeadManaging stores an organization name on a lead, FlitStack extracts it as a standalone Company record in Nutshell. If the company name is blank or ambiguous, a placeholder company record is created and flagged for your team to verify and rename.
LeadManaging
Lead / Deal / Opportunity
Nutshell
Lead (Opportunity)
1:1LeadManaging deals and opportunities map to Nutshell Leads. The deal name, amount, close date, and stage all transfer. Nutshell Lead Confidence (0–100 rating) can receive a mapped value if your source has a comparable score; otherwise it defaults to 50 and can be updated manually after migration.
LeadManaging
Lead / Pipeline name
Nutshell
Pipeline (Nutshell Pipeline)
1:1LeadManaging pipeline names map to Nutshell Pipeline objects. Each pipeline in the source becomes its own Nutshell Pipeline with named stages. Stage order and labels are preserved; stage probability is not carried over unless your source stores explicit probability values, since Nutshell stages do not have native probability fields.
LeadManaging
Lead / Lead status
Nutshell
Lead status field
1:1LeadManaging lead status values (New, Contacted, Qualified, Lost, Won) map to Nutshell's Lead Status pick-list. We apply a value-by-value mapping — statuses that have no exact Nutshell equivalent receive the closest available option and are flagged in the mapping plan for your review before the migration runs.
LeadManaging
Lead / Custom properties
Nutshell
Custom fields (Person / Company / Lead)
1:1LeadManaging custom fields — such as lease_type, unit_number, move_in_date, or referral_source — do not have a native equivalent in Nutshell. FlitStack creates matching custom fields on the appropriate Nutshell object (Person, Company, or Lead) before the migration, preserving the original data type and any pick-list values the field uses.
LeadManaging
Lead / Tags
Nutshell
Custom field (text or picklist)
1:1LeadManaging's tag model has no direct Nutshell equivalent. Tags migrate as a text custom field storing comma-separated values, or as a multi-select pick-list if the total tag set is small and well-defined. Teams that rely heavily on tagging for segmentation should review the resulting field in Nutshell and consider using Nutshell's built-in filters instead.
LeadManaging
Call / Email / Meeting / Note
Nutshell
Activity (calls, emails, meetings, notes)
1:1Activity records from LeadManaging map to Nutshell Activities. Calls become call activities, emails become email activities, meetings become meeting activities, and notes become note records — all linked to the correct Person, Company, or Lead. Original timestamps and owner attribution are preserved on each record.
LeadManaging
Attachment / File
Nutshell
File (Nutshell Files)
1:1File attachments stored against lead records in LeadManaging are downloaded and re-uploaded to Nutshell's file storage. Nutshell's file size limits apply; files exceeding the limit are flagged for manual re-upload by your team. Inline images in notes are extracted, re-hosted, and the note body is updated with the new image URLs.
LeadManaging
Owner / Assigned user
Nutshell
Owner (Nutshell user)
1:1LeadManaging owner assignments resolve by matching the owner's email address to a Nutshell user. If no matching Nutshell user exists, the record is assigned to a designated fallback owner and flagged in the migration report. You should ensure all active LeadManaging users have been invited to Nutshell before the migration date.
LeadManaging
Lead / Lead Confidence
Nutshell
Lead Confidence (custom numeric field)
1:1If LeadManaging stores a numeric confidence or priority score on leads that has no direct equivalent in Nutshell, we migrate it as a custom numeric field on the Lead object. Nutshell's native Lead Confidence (0–100 rating) coexists with this field; your team can choose which to use for pipeline sorting.
LeadManaging
Lead / Address fields
Nutshell
Address field (on Person or Company)
many:1LeadManaging stores address components separately (street, city, state, zip, country). These merge into Nutshell's single-line address field. When multiple address records exist for one person, FlitStack selects the most recently modified address by default and surfaces any alternates as a note on the Person record.

Migration approach
Audit LeadManaging data and build the mapping specification
FlitStack connects to your LeadManaging instance using scoped API credentials and exports all active records — people, companies, leads, deals, and activities. We cross-reference every field against Nutshell's schema to identify direct matches, custom field requirements, and any pick-list value mappings. The result is a field-level mapping specification delivered for your review before any data moves. This step also identifies orphaned records (people without companies, leads without owners) so your team can resolve them before migration day.
Create Nutshell custom fields and configure pipelines
Before data lands, FlitStack delivers a custom-field creation plan listing every LeadManaging property that requires a new Nutshell field — the field name, data type, and object to attach it to. Your Nutshell admin creates these fields (or FlitStack creates them via the API where permitted). We also provide pipeline configuration notes so your team can set up Nutshell Pipelines with stage names matching your current LeadManaging deal stages. This step runs in parallel with your data-cleanup review.
Migrate companies and people first, then leads and deals
Nutshell's foreign-key model requires Companies to exist before People can reference them, and People to exist before Leads can be associated with them. FlitStack sequences the migration in dependency order: Companies land first, then People with their primary company link resolved, then Leads and deals that reference those companies and people. Activity records (calls, emails, meetings, notes) are loaded after their parent records exist so the relationship links are valid. Each batch runs with a validation pass that checks record counts and field-level integrity before the next batch starts.
Run a sample migration and generate a field-level diff
A representative slice — typically 100–300 records spanning people, companies, leads, and activities — migrates first and lands in Nutshell for your team to verify. FlitStack generates a field-level diff comparing source values against destination values for every mapped field. You can confirm that custom property values appear correctly, that owner attribution maps to the right Nutshell users, and that pipeline names are preserved. This step surfaces any mapping corrections before the full migration commits.
Execute full migration with delta pickup and rollback window
The full dataset migrates against Nutshell using the validated mapping. A 24–48 hour delta pickup window runs simultaneously, capturing any LeadManaging records modified or created during the migration window. All operations are logged to an audit trail. If reconciliation detects missing records or data integrity issues, FlitStack can execute a one-click rollback that removes migrated records from Nutshell without affecting your LeadManaging source. You switch your team to Nutshell at the agreed go-live time.
