Overview
Jarvis Legal structures its data around legal-practice objects: Clients, Matters, Time Entries, and Invoices. Matter-level fields like case_type, court, opposing_counsel, and matter_status have no native equivalent in Nutshell's CRM model. We resolve this by mapping Jarvis Matters to Nutshell Deals, then using Nutshell's custom fields for legal-specific metadata on the Deal object. Client contacts migrate as Nutshell People and link to their Matter-Deals via the deal's primary contact. Time entries become Nutshell Tasks with duration in minutes, billable status, and billing rate stored as custom fields. Attorney and staff assignments resolve by email match to Nutshell users. Documents and files attached to Jarvis matters do not migrate directly — we re-upload them to Nutshell Files and link them to the corresponding Deal. Workflows, automations, document templates, and trust-accounting rules are not transferred; those require manual rebuild in Nutshell or a legal-specific add-on. The migration API path uses Jarvis's data export endpoint and Nutshell's REST API with a 429-handling retry layer to respect rate limits. FlitStack runs a sample migration first, then executes the full cutover with a 24–48 hour delta window to capture any in-flight changes made during the transition.

Object mapping
Each row shows how a Jarvis Legal 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.
Jarvis Legal
Client
Nutshell
Person
1:1Jarvis Clients map directly to Nutshell People. Name, email, phone, job_title, and address fields have direct equivalents. Clients without an email receive a placeholder email in Nutshell. Internal notes from Jarvis transfer as a custom field on the Person record.
Jarvis Legal
Matter
Nutshell
Deal
1:1Jarvis Matters have no native Nutshell equivalent, so they map to Nutshell Deals. The Matter name becomes the Deal name, estimated_amount maps to Amount, and responsible_attorney links as the Deal's assigned contact. Legal metadata (case_type, court, opposing_counsel, case_number, practice_area) requires custom fields on the Deal in Nutshell.
Jarvis Legal
Time Entry
Nutshell
Task (Activity)
1:1Jarvis Time Entries map to Nutshell Tasks. Hours convert to duration in minutes. Entry description becomes the Task subject, date maps to due date, and timekeeper becomes the assigned contact. Billable flag and billing_rate store as custom fields on the Task since Nutshell does not have native billable tracking on Activities.
Jarvis Legal
Invoice
Nutshell
Custom Field on Deal
1:1Nutshell has no Invoice object. Jarvis invoices do not migrate as standalone records. Invoice number, total amount, outstanding balance, and payment status are stored as custom fields on the associated Matter-Deal for billing reference. Actual invoice generation must happen outside Nutshell or via a legal billing integration.
Jarvis Legal
Document / File
Nutshell
Nutshell Files + Note attachment
1:1Jarvis stores matter documents in a folder structure. Nutshell has no native document management system. We download all documents, re-upload them to Nutshell Files, and attach them to the corresponding Deal. Folder hierarchy is lost; we record the original folder path in a custom field on each file.
Jarvis Legal
Matter Status
Nutshell
Custom field on Deal
1:1Jarvis matter_status values such as active, pending, closed, and on_hold have no direct equivalent in Nutshell's Deal model. We create a Status_Matter__c pick-list field on the Deal object in Nutshell and map the values one-to-one. Once created, the field displays on the Deal layout for attorney reference, allowing teams to track matter status directly within the CRM without switching contexts.
Jarvis Legal
User / Attorney
Nutshell
Nutshell User
1:1Jarvis team members and attorneys map to Nutshell users by email address match. Before migration, Nutshell administrators must create user accounts for every attorney and staff member who owns records. Unmatched owners receive a fallback assignment and are flagged for manual resolution.
Jarvis Legal
Matter Contact (client link)
Nutshell
Deal primary contact
1:1Jarvis associates each matter with a client. That client-Contact becomes the primary contact on the Nutshell Deal. If a matter links to multiple clients, the primary client maps to the Deal's contact field; secondary clients surface in a custom field for reference.
Jarvis Legal
Custom Field (Matter-level)
Nutshell
Custom Field on Deal
1:1Jarvis custom fields on matters (such as practice_area, billing_rate_override, referral_source) map to Nutshell Deal custom fields. Field types are preserved where Nutshell supports them (text, pick-list, date, number). Fields with unsupported types (e.g., multi-select pick-lists) convert to text fields with a migration note in the field_mapping log.
Jarvis Legal
Workflow / Automation
Nutshell
None
1:1Jarvis workflows covering matter progression rules, deadline triggers, and document automation do not transfer. Nutshell's automation engine handles sales follow-up sequences only. We export workflow definitions as a structured reference document so your team can rebuild logic in Nutshell or a complementary automation tool.
Jarvis Legal
Trust Accounting
Nutshell
None
1:1Jarvis trust accounting maintains client ledger entries tracking funds received, held in trust, and disbursed. Nutshell CRM lacks an accounting module entirely, so these records have no migration path within the platform. Firms requiring trust accounting capabilities after migration should evaluate a dedicated legal billing platform to operate alongside Nutshell for financial tracking needs.

Migration approach
Extract full data export from Jarvis Legal
FlitStack initiates a full data export from Jarvis Legal using the platform's data export endpoint, pulling all Clients, Matters, Time Entries, Invoices, and Document metadata. We validate record counts against your reported totals before proceeding. Any records that fail to export (due to deleted-while-running data or permission restrictions) are flagged in a pre-flight report. We also export workflow definitions as a structured JSON reference file for your team to use during the Nutshell rebuild phase.
Map Jarvis schema to Nutshell objects and create custom fields
We map the Jarvis data model to Nutshell's object structure: Clients to People, Matters to Deals, Time Entries to Tasks. Legal-specific fields (case_type, court, opposing_counsel, matter_status, billing_rate) are identified as requiring custom fields in Nutshell. Before migration runs, FlitStack generates a custom field creation checklist so your Nutshell administrator can pre-create all required fields on the Deal and Task objects. This prevents migration failures caused by missing field targets.
Resolve owner and contact matches by email
Jarvis attorney and staff assignments resolve to Nutshell users by email match. Before migration, we validate that every Jarvis user has a corresponding Nutshell user account. Unmatched owners are flagged with the responsible attorney name and email so your team can create accounts or assign a fallback user. Contacts on Matter records resolve to Nutshell Person records using the client email — any Matter without a linked client contact is flagged for manual assignment to a Nutshell Person before the deal migration phase.
Run sample migration with field-level diff
A representative slice — typically 50–100 records spanning clients, matters, and time entries — migrates first into your live Nutshell environment. We generate a field-level diff report comparing every Jarvis field value against the corresponding Nutshell field value. You review the diff to verify that matter metadata maps correctly to custom Deal fields, that timekeeper assignments resolve to the correct Nutshell Person, and that billable flags appear on Tasks. No full migration commits until you approve the sample results.
Execute full cutover with delta-pickup window
The full migration loads all validated records into Nutshell. A 24–48 hour delta-pickup window runs concurrently — any matter, contact, or time entry created or modified in Jarvis during the cutover is pulled in the delta pass. Documents download from Jarvis and re-upload to Nutshell Files, attached to their corresponding Matter-Deals. FlitStack generates a reconciliation report comparing source record counts to destination record counts. If reconciliation fails, one-click rollback reverts all written records. Audit log captures every operation for post-migration review.
