Overview
Moving from Project Drive to Microsoft Project is a structural migration that surfaces two compounding constraints: Project Drive has no documented public API, so all data extraction relies on authenticated bulk export sessions that limit throughput and add timeline risk on large accounts, and Project Drive's native budget and cost fields require explicit mapping to Microsoft Project's cost, resource rate, and baseline schema. We script authenticated UI-based extraction to pull structured CSV data for Projects, Tasks, Subtasks, and Milestones, then reconstruct the Gantt dependency graph from Project Drive's visual layout as explicit Finish-to-Start and Start-to-Start relationship records in Microsoft Project. Budget fields migrate as task-level cost fields or project-level cost columns depending on the customer's chosen cost-tracking model. We do not migrate automations, custom fields beyond standard typed fields, or calendar sync data; we deliver a written inventory of any such configuration for the customer's admin to rebuild in Microsoft Project.

Object mapping
Each row shows how a Project Drive object lands in Microsoft Project, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Project Drive
Project
Microsoft Project
Project
1:1Project Drive Projects map directly to Microsoft Project as the top-level container. We extract project name, description, status (Active, Completed, On Hold), start date, finish date, and creation timestamp. Project Drive's project-level metadata becomes project summary task fields in Microsoft Project. Export is straightforward via the application's project-level CSV export where available, or via scripted UI extraction sessions for accounts with many projects.
Project Drive
Task
Microsoft Project
Task
1:1Project Drive Tasks map to Microsoft Project Tasks with Name, Start, Finish, Duration, and PercentComplete preserved. Task status (Not Started, In Progress, Completed) maps to the Microsoft Project PercentComplete and IsMarked flag. Task notes migrate as Task Notes field in Microsoft Project. Where Project Drive exports tasks with a parent-reference to indicate hierarchy, we preserve the outline level by setting the Summary field appropriately.
Project Drive
Subtask
Microsoft Project
Task (child of Summary Task)
1:manyProject Drive Subtasks nest under Tasks. We collapse the two-level hierarchy by promoting Subtasks to Tasks linked under a Summary Task that represents the parent Task. The outline level in Microsoft Project is set to preserve the visual hierarchy. Some destination configurations may choose to flatten all Subtasks to a flat task list with a custom Parent_Task__c field; the customer chooses the flattening strategy during scoping.
Project Drive
Milestone
Microsoft Project
Task (Milestone)
1:1Project Drive Milestones export as standalone records with a milestone flag and a target date. We create Microsoft Project Tasks with Duration set to zero and the Milestone checkbox enabled. The milestone name and date migrate directly. If Project Drive does not expose a dedicated milestone field in export, we identify milestones by their task type marker in the Gantt view layout data and create the equivalent Milestone task at migration time.
Project Drive
Gantt Dependency (reconstructed)
Microsoft Project
Task Dependency
lossyProject Drive displays task relationships visually in Gantt view, but exported data may flatten dependency links into simple ordering fields (e.g., PredecessorName or task sequence index). We reconstruct explicit dependency declarations from the Gantt visual layout data, inferring Finish-to-Start relationships from the sequential ordering. We then write Predecessor and Successor records in Microsoft Project using the Successors and Predecessors task fields. Any explicitly declared dependency types in the source (e.g., Start-to-Start) are preserved if present in the export data.
Project Drive
User / Assignee
Microsoft Project
Resource
1:1Project Drive Users and task Assignees map to Microsoft Project Resources. We extract the user roster from the export and create Resource records with the user's name and email. Per-task assignee assignments become Task Assignments in Microsoft Project with the Resource Name, Units, and Start/Finish dates mapped from the task assignment data. If Project Drive exports a generic assignee field without resource rate data, we create Material Resources rather than Work Resources in the destination.
Project Drive
Budget
Microsoft Project
Project Summary Task Cost Fields
lossyProject Drive Budget fields map to Microsoft Project cost columns. We map the Project Drive budget amount to the project-level Budget field or a custom cost field, depending on whether the customer tracks budget at the project level or the summary task level. The customer chooses the cost tracking model during scoping: project-level budget as a single value, or cost-per-task using the Budget field with cost accumulation formulas.
Project Drive
Cost Fields
Microsoft Project
Task Cost + Fixed Cost
lossyProject Drive cost data per task or per project requires mapping to Microsoft Project's cost schema, which distinguishes between Fixed Cost (a lump sum assigned to a task), Fixed Cost Accrual, Per-Unit Cost (resource rate multiplied by units), and Cost resources. We analyze the Project Drive export schema during discovery to identify cost fields and propose a mapping to the appropriate Microsoft Project cost column. Any null or zero cost values are flagged for the customer's confirmation before migration.
Project Drive
Attachment
Microsoft Project
Document (SharePoint / Project Attachments)
1:1Project Drive task and project attachments export as binary file blobs with original filename and content type preserved. In Microsoft Project for the web, attachments link to the project's associated SharePoint document library. We carry over the file blob and re-attach it to the corresponding task or project in the destination. Link integrity depends on the target's SharePoint storage being configured; we verify the SharePoint site exists and the migration user has contribute permissions before file re-attachment.
Project Drive
Task Start Date
Microsoft Project
Task Start
1:1Project Drive Start Date and End Date on tasks migrate directly to Microsoft Project Start and Finish fields. If the project-level Project Guide Start Date is set, it applies as the project default; individual task dates migrate as-is. Where Project Drive exports only a Start date without an explicit End date, we compute Finish from Start plus Duration using the project calendar.
Project Drive
Task Status
Microsoft Project
Task PercentComplete
lossyProject Drive task status values (Not Started, In Progress, Completed) map to Microsoft Project PercentComplete. Not Started maps to 0%, In Progress maps to a midpoint value (customer choice between 25%, 50%, or 75% based on the source data's granularity), and Completed maps to 100%. We flag any non-standard status values during discovery for manual mapping.

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.
Project Drive gotchas
No public API documented for bulk data export
Budget and cost fields require schema mapping at destination
Gantt sequencing does not always preserve inter-task dependency details
Microsoft Project gotchas
Project for the web is being retired and merged into Microsoft Planner
Planner-tier portfolio features are incomplete despite Plan 5 labeling
Web app constraint controls are weaker than the Windows desktop client
Project requires a separate license not bundled with standard Microsoft 365
Project Online API is edition-gated and inconsistently documented
Pair-specific challenges
Migration approach
Discovery and export feasibility assessment
We audit the Project Drive account for data volume (projects, tasks, subtasks, milestones, attachments, cost fields), assess the available export functionality (project-level CSV, task-level CSV, bulk download capabilities), and identify any export constraints (session timeout limits, page-size limits, required UI navigation). We produce a written discovery report that confirms the export strategy and flags any data that cannot be extracted programmatically. We also confirm the Microsoft Project destination type (desktop MPP, Project for the web, or Project Online) and the associated SharePoint site connectivity.
Export scripting and batch extraction
We script authenticated browser-based extraction sessions to pull structured CSV data from Project Drive in project-level batches. Each batch covers a single project and its tasks, subtasks, milestones, and attachments. We run extraction overnight where possible to avoid session timeouts and to manage application-level throttling. We validate each batch export for completeness (record count against UI-visible count) before proceeding. The output is a set of structured CSVs organized by project with all metadata columns preserved.
Gantt dependency reconstruction
We analyze the Project Drive export data to identify implicit task ordering from the Gantt visual layout fields (task sequence index, predecessor name, or visual offset data). We reconstruct explicit Finish-to-Start dependency records for sequential tasks and flag any tasks that imply non-sequential relationships for manual confirmation. The reconstructed dependency map becomes the Predecessors field in Microsoft Project. We validate the dependency graph in a test project to confirm scheduling propagation works correctly before running production migration.
Cost field mapping and schema configuration
We map Project Drive budget and cost fields to the appropriate Microsoft Project cost columns based on the customer's chosen cost tracking model. We configure custom cost fields in Microsoft Project if the standard Fixed Cost and Cost columns do not cover the source schema. We set up the project summary task with the project-level budget value if the customer tracks budget at that level. All cost field mappings are documented in the mapping specification for customer sign-off before import.
Sandbox migration and reconciliation
We run a full migration into a Microsoft Project test environment (a dedicated SharePoint site or Project for the web test plan) using production-like data volume. The customer's project manager reconciles task counts, milestone counts, dependency counts, and cost totals against the source Project Drive export. We spot-check 20-30 random tasks for field-level accuracy (dates, durations, assignees, cost values) and validate that the dependency graph propagates scheduling correctly. Any mapping corrections happen in this phase.
Production migration and cutover
We run production migration in record-dependency order: Projects first, then Tasks with Outline level and Summary relationships, then Milestones, then Dependencies, then Attachments, then Cost fields. Each phase emits a row-count reconciliation report. We freeze Project Drive writes during cutover, run a final delta migration of any records modified during the window, then enable Microsoft Project as the system of record. We deliver a written inventory of any automations, custom fields beyond standard typed fields, and calendar sync configurations that require manual rebuild in Microsoft Project.
