Overview
Moving from CRUMP CRM to Zoho CRM requires extracting data from the underlying Microsoft Dynamics 365 instance that CRUMP CRM runs on, then restructuring that data to fit Zoho's module architecture. CRUMP CRM bundles CRM, helpdesk, project management, and invoicing under a single Dynamics 365 layer; Zoho CRM exposes these as separate modules (or custom modules) with field-type constraints that vary by edition. We begin every engagement by auditing the source org's Dynamics 365 licence tier, enumerating active entities, and documenting any fields that fall outside the licence scope before writing a single record to Zoho. Projects, Tickets, and Invoices do not have direct Zoho CRM equivalents and require a custom module or Zoho Books configuration decision made during scoping. We do not migrate Workflows, automations, or invoicing templates; we deliver a written inventory of every active automation for the customer's admin to rebuild in Zoho's Blueprint and workflow tools.
Every standard and custom field arrives verified.

Object mapping
Each row shows how a CRUMP CRM object lands in Zoho CRM, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
CRUMP CRM
Contact
Zoho CRM
Contact or Lead
1:manyCRUMP CRM Contacts map directly to Zoho CRM Contacts via the Dynamics 365 Contact entity. If the source org uses a Lead entity for unqualified prospects, those split to Zoho Lead. We use the Dynamics 365 parentcustomerid property and any custom lifecycle or status fields to determine the split. Contacts without a parent Account in Dynamics 365 become Zoho Contacts with no Account linkage; we flag these for the admin to resolve after migration.
CRUMP CRM
Account
Zoho CRM
Account
1:1CRUMP CRM Accounts (Companies) map 1:1 to Zoho CRM Accounts. The Dynamics 365 accountid becomes a custom field z_dynamics_id__c on the Zoho Account for reconciliation. Parent-child account hierarchies migrate with the parentaccountid reference resolved to the Zoho Account record created in the same pass.
CRUMP CRM
Deal
Zoho CRM
Deals
1:1CRUMP CRM Deals (Dynamics 365 Opportunity entity) map to Zoho CRM Deals. The Dynamics 365 opportunityid is preserved in z_dynamics_id__c on the Zoho Deal. Pipeline stages from Dynamics 365 become Zoho Stage values; we map stage names at migration time using the customer's stage matrix. Deal value, close date, and probability migrate as numeric, date, and percentage fields respectively.
CRUMP CRM
Project
Zoho CRM
Custom Module or Zoho Projects
lossyProjects in CRUMP CRM live in the Project Management module (Dynamics 365 Project Service Automation or a custom project entity). Zoho CRM does not have a native project management module. During scoping we determine whether the customer uses Zoho Projects as a separate product (requiring a cross-product migration) or wants projects as a Zoho CRM Custom Module. If Custom Module, we pre-create the module schema including status, dates, assigned team, and linked contact fields before import.
CRUMP CRM
Ticket
Zoho CRM
Cases or Custom Module
lossyHelpdesk tickets in CRUMP CRM (Dynamics 365 Incident entity) map to Zoho CRM Cases if the destination Zoho org includes Service Cloud. If Service Cloud is not in scope, tickets migrate to a Custom Module with Status, Priority, Subject, Description, and contact linkage. Custom fields on tickets are enumerated during audit and created in Zoho before import; Standard edition customers should note that Lookup fields are not available in Zoho CRM Standard.
CRUMP CRM
Invoice
Zoho CRM
Zoho Books Invoices or Custom Module
lossyInvoicing in CRUMP CRM is part of the bundled suite and may use the Dynamics 365 finance entities. Zoho CRM does not include full accounting. If the customer uses Zoho Books, we migrate invoice records (invoice number, date, line items, totals, payment status) to Zoho Books and link the Zoho Books Invoice to the corresponding Zoho CRM Account or Deal. If Zoho Books is not in scope, invoices migrate as a Custom Module in Zoho CRM with read-only financial fields.
CRUMP CRM
Task
Zoho CRM
Tasks
1:1CRUMP CRM tasks exist across CRM tasks, project tasks, and helpdesk tasks. We deduplicate by Dynamics 365 activityid and label each task by its origin module (CRM, Project, or Ticket) in a custom field task_origin__c so the Zoho admin can apply filters post-migration. Status, Priority, ActivityDate, and Subject migrate directly. Task assignments resolve hubspot_owner_id-equivalent Dynamics 365 systemuser references to Zoho User records by email match.
CRUMP CRM
User
Zoho CRM
User
1:1CRUMP CRM user accounts are Dynamics 365 systemuser records. We match by email to Zoho User records. Any Dynamics 365 user without a matching Zoho User goes to a reconciliation queue; the customer provisions the Zoho User before record migration continues. Inactive Dynamics 365 users are imported as inactive Zoho Users to preserve historical assignment data without inflating the active seat count.
CRUMP CRM
Attachment
Zoho CRM
Attachments
1:1CRUMP CRM attachments stored in Dynamics 365 Notes or SharePoint-linked document locations require a separate file-level export pass. We do not migrate binary blobs through the API layer without a documented export method. If the source org uses SharePoint integration for file storage, we extract file URLs and recreate Attachment records in Zoho CRM pointing to the source SharePoint location. A full binary file migration is a separate scope item.
CRUMP CRM
Custom Entity
Zoho CRM
Custom Module
1:1CRUMP CRM custom entities created on top of Dynamics 365 are enumerated during the audit phase. Each custom entity and its fields are documented individually since no two Dynamics 365 deployments share the same custom schema. We pre-create the corresponding Zoho CRM Custom Module with matching field types, preserve any lookup relationships to standard entities, and import records after the standard entity migration completes. Note that Zoho CRM Standard excludes custom modules; Professional or above is required.

Migration approach
Dynamics 365 licence and entity audit
We connect to the source CRUMP CRM org via its underlying Dynamics 365 instance (typically crump.crm.dynamics.com) using admin or service account credentials with read access. We enumerate all accessible entities, document field types and names for each, and verify that the licence tier exposes the entities required for migration. We identify custom entities, note the entity relationship diagram, and flag any entities that fall outside the licence scope. This output is a written entity inventory with field counts per entity, which drives the Zoho edition recommendation and the custom module schema design.
Zoho edition selection and module schema design
We recommend a Zoho CRM edition based on the audit findings: Standard for basic CRM-only migrations under 50 fields per module and no custom entities; Professional if custom fields and assignment rules are needed; Enterprise or above if custom modules, Blueprint, or the 300-field limit per module applies. We pre-create the destination schema in Zoho: standard modules (Account, Contact, Deal, Case, Task), any custom modules for Projects and Tickets, custom fields with correct types (Lookup fields are excluded in Standard), and picklist values matching the Dynamics 365 option set values. Schema is built in a Zoho sandbox or development org first and validated before production migration begins.
Data extraction from Dynamics 365 in dependency order
We extract data from Dynamics 365 using the web API or OData endpoint in record-dependency order: Users first (resolved by email for Zoho User matching), then Accounts, Contacts, Deals, Tasks, and custom entities. We export in batches using OData $filter and $top pagination to avoid overwhelming the Dynamics 365 instance. Each entity export produces a CSV or JSON file with the Dynamics 365 primary key preserved in a custom field for reconciliation. We flag duplicate records, missing required fields, and orphaned parent references (Contacts without an Account) for the customer to resolve before import.
Staging migration and reconciliation
We run a full migration into a Zoho development or sandbox environment using the same record volumes as production. The customer's admin reviews record counts, spot-checks 20-30 random records per entity against the Dynamics 365 source, and validates field mappings and picklist values. Any field type mismatches, truncated text, or missing lookups are corrected in the mapping document before production migration begins. This stage also validates that Zoho field limits are not exceeded for any module on the selected edition.
Production migration in dependency order
We run production migration in the same dependency order used in staging: Users (manually provisioned and validated first), Accounts, Contacts with AccountId resolved, Deals with AccountId and OwnerId resolved, Cases or custom ticket module, Tasks with OwnerId resolved, then custom entities last. We use Zoho's API with batch chunking and exponential backoff on rate-limit responses. Each phase emits a row-count reconciliation report showing source count versus destination count. Any records rejected during import are logged with the error reason and retried in a corrective pass.
Cutover, validation, and automation handoff
We freeze CRUMP CRM writes during cutover, run a final delta migration of any records created or modified during the migration window, then set Zoho CRM as the system of record. We deliver a written automation inventory documenting every active Dynamics 365 workflow, Power Automate flow, and custom entity business rule with its trigger, conditions, and recommended Zoho Blueprint or workflow rule equivalent. We do not rebuild automations in Zoho; that is a separate engagement or an internal admin task. We offer a one-week hypercare window for reconciliation issues raised by the customer's team.
