Overview
The Lead Guerrilla to Microsoft Microsoft Dynamics 365 Sales migration is constrained first by the absence of a documented API on the source side. Lead Guerrilla publishes no REST endpoint, GraphQL endpoint, or developer portal, so every data export requires staged CSV downloads from the admin UI, page-by-page activity logging, and direct coordination with 1CRM Systems Corp. for bulk record access. On the destination side, Microsoft Dynamics 365 Sales separates unqualified prospects (Lead) from qualified buyers (Contact attached to Account), which requires resolving Lead Guerrilla's single Contact record model into the correct split at migration time. We preserve Lead Guerrilla lead scoring values as a custom numeric field on the Lead or Contact in Dynamics 365, and we transfer campaign enrollment history as a custom multi-select or related entity. Marketing automation rules, landing pages, and web forms are not migratable as code or portable content; we deliver a written rebuild playbook for each. Automation reconstruction, form rebuild, and Power Automate flow configuration are separate workstreams outside the migration scope.
Every standard and custom field arrives verified.

Object mapping
Each row shows how a Lead Guerrilla object lands in Microsoft Dynamics 365 Sales , including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Lead Guerrilla
Contact
Microsoft Dynamics 365 Sales
Lead or Contact (split required)
1:manyLead Guerrilla stores all prospects and customers in a single Contact object with no separate Lead concept. Microsoft Dynamics 365 Sales separates unqualified prospects into Lead records and qualified buyers into Contact records attached to Account records. We define the split rule during scoping based on the customer's lead score thresholds and campaign enrollment status. Contacts with a lead score above the customer's qualification threshold map to Contact records; below the threshold map to Lead records. The original Lead Guerrilla lead score migrates as a custom numeric field lg_original_score__c on both Lead and Contact for audit trail and future segmentation.
Lead Guerrilla
Company
Microsoft Dynamics 365 Sales
Account
1:1Lead Guerrilla Companies map directly to Microsoft Dynamics 365 Sales Account records. The Company name becomes Account Name, the domain field maps to Website, and any address fields map to the address composite on Account. Account is inserted before Contact import so that the parent AccountId lookup is satisfied at Contact insert time. We use Company name as the dedupe key for duplicate detection during import.
Lead Guerrilla
Campaign
Microsoft Dynamics 365 Sales
Campaign
1:1Lead Guerrilla Campaigns (multi-channel sequences across email, SMS, Twitter, and web notifications) map to Microsoft Dynamics 365 Sales Campaign. The campaign channel configuration, timing rules, and enrollment triggers are captured as campaign configuration notes. Dynamics 365 Campaign tracks member responses as Campaign Responses. We preserve campaign enrollment history as Campaign Member records linked to the corresponding Contact or Lead.
Lead Guerrilla
Segment
Microsoft Dynamics 365 Sales
Dynamic Distribution Group or Security Group
lossyLead Guerrilla Segments (behavior-based or demographic contact groupings) have no direct Dynamics 365 equivalent. We export segment definitions including filter conditions and member counts, then translate them into Dynamics 365 Dynamic Distribution Groups (Exchange-based) or Power Platform Security Groups with dynamic membership rules. The customer chooses the distribution model during scoping. Segment membership is not migrated as a static group because contacts change state over time.
Lead Guerrilla
Lead Scoring
Microsoft Dynamics 365 Sales
Grade/Score fields on Lead and Contact
1:1Lead Guerrilla calculates a numeric lead score from website behavior, form submissions, and campaign interactions. We export the current score value per Contact as a custom integer field lg_lead_score__c on both Lead and Contact in Dynamics 365. The scoring model itself (point values per action, weightings, thresholds) is not portable. We document the original scoring model in the automation rebuild playbook so the customer's marketing team can implement an equivalent scoring logic in Power Automate or a third-party scoring ISV.
Lead Guerrilla
Activity
Microsoft Dynamics 365 Sales
Task, EmailMessage, Event
1:1Lead Guerrilla Activities track email opens, page visits, form submissions, SMS sends, and tweet engagement with timestamps and event types. These map to Dynamics 365 Activity (Task), EmailMessage (for email open/click events stored as email tracking records), and Event (for scheduled or completed meetings). High-volume activity records are chunked for Dataverse API ingestion. We preserve the original timestamp as ActivityDate for timeline ordering.
Lead Guerrilla
Tag
Microsoft Dynamics 365 Sales
Tag or Note
1:1Lead Guerrilla Tags on Contacts and Companies map to Dynamics 365 Tags (introduced in 2020 Release Wave 2 for Unified Interface) or to a custom multi-select picklist field if the destination org uses an older UI version. Tag naming conventions are preserved exactly as-is to maintain segmentation logic that depends on specific naming patterns.
Lead Guerrilla
Landing Page
Microsoft Dynamics 365 Sales
SharePoint or Power Pages
lossyLead Guerrilla Landing Pages are content assets created in the platform's internal builder with no export path for page HTML or embed scripts. We export page metadata (title, URL slug, published status, redirect configuration) as a written inventory. The customer's web team rebuilds the pages in their target content platform (SharePoint, Power Pages, or a CMS). We provide field-level mapping between the Lead Guerrilla form fields and the replacement destination form fields so the rebuild is guided.
Lead Guerrilla
Web Form
Microsoft Dynamics 365 Sales
Power Pages or Dynamics 365 Marketing Form
lossyLead Guerrilla Web Forms collect contact data via embedded tracking widgets. We export form field definitions, submission mappings, and redirect behavior as a written specification. Form logic (field visibility conditions, required field rules, thank-you message text) is documented for rebuild in Power Pages or Dynamics 365 Marketing. The form embed scripts are not portable and require rewrite.

Pair-specific challenges
Migration approach
Discovery and export choreography planning
We audit Lead Guerrilla through the admin UI: contact and company list CSV exports, campaign configuration screenshots, segment filter definitions, landing page metadata, web form field definitions, and activity log review. Because there is no API, we map every data object to an export method (admin UI CSV, manual screenshot, vendor-assisted bulk export request). We pair this with a Microsoft Dynamics 365 Sales environment review to confirm the target edition (Professional at $65/user or Enterprise at $95/user), existing entity schema, security roles, and any Power Automate flows already in place.
Automation and form cataloging
We document every active Lead Guerrilla automation via screenshots and configuration notes from the admin UI, capturing triggers, conditions, actions, delays, and enrollment rules. We separately document every landing page and web form with field definitions, redirect logic, and thank-you message content. This catalog becomes the automation rebuild playbook delivered to the customer at cutover. We do not execute the rebuild; it is the customer's marketing team's responsibility post-migration.
Lead-Contact split rule and Dynamics 365 schema design
We define the split rule for Lead Guerrilla Contacts into Dynamics 365 Leads and Contacts based on the customer's lead score thresholds and qualification criteria. We configure the Dynamics 365 schema: Account entity from Companies, Contact entity with lg_lead_score__c custom field, Lead entity with lg_lead_score__c custom field, Campaign entity with member tracking, and any required security roles. Schema is deployed into a Sandbox org for validation before production migration begins.
Vendor-assisted export coordination
We coordinate with 1CRM Systems Corp. to request bulk record export assistance for any data volumes that exceed what can be practically exported via admin UI CSV downloads (typically anything over 5,000 records). We document the request timeline in the project plan and use the admin UI CSV path as the primary backup. We extract all data into a staging format and perform pre-flight validation (record counts, field completeness, duplicate detection) before transformation begins.
Transformation and sandbox migration
We transform Lead Guerrilla records into Dynamics 365 format: Companies to Accounts, Contacts split into Leads and Contacts based on the qualification rule, Campaigns to Campaigns with Campaign Members, Activities to Tasks and EmailMessages with timestamps preserved. We run the full migration into a Dynamics 365 Sandbox org first. The customer's RevOps lead reconciles record counts and spot-checks 25-50 records against the Lead Guerrilla source before signing off on the mapping for production migration.
Production migration and cutover
We run production migration in dependency order: Accounts first (from Companies), then Leads and Contacts with the split rule applied and parent AccountId resolved, then Campaigns with member enrollment history, then Activity history via Dataverse API with chunking and exponential backoff on rate limits. We freeze Lead Guerrilla writes during the cutover window, run a final delta migration of any records modified during the migration window, then enable Microsoft Dynamics 365 Sales as the system of record. We deliver the automation rebuild playbook and form rebuild specification at this time.
