Overview

What this migration involves

Moving from OnePlan to Asana is a migration from a portfolio-centric PPM platform to a task-centric work management platform. OnePlan's hierarchical plan types (Programs containing Projects containing Work Plans) map to Asana's Team-Project-Section-Task structure, and we resolve the structural translation during scoping. OnePlan lacks a documented public API, so we extract data via the Migration Tool CSV output and load it into Asana using the Asana REST API with batch processing. We flag that OnePlan's Migration Tool is append-only, cannot update existing records, and requires manual deduplication if the destination already contains data. Stage Gate Workflows, document attachments, and SharePoint-linked files do not migrate; we deliver a written inventory of these gaps for your admin to rebuild. Financial plan data and resource allocation over time migrate where Asana's data model can represent them, with custom fields carrying forward on a template-by-template basis rather than from a centralized configuration.

Field-level fidelity

Every standard and custom field arrives verified.

Why teams make this switch

Two sides of the same decision

Leaving

OnePlan logo

OnePlan

What's pushing teams away

  • Users report that some features feel glitchy and unresolved issues persist in the backlog, creating frustration with platform stability.
  • Time-zone support challenges make it difficult for global teams to get timely assistance when issues arise during critical project phases.
  • The platform lacks a robust public API for ongoing integrations, limiting teams that need real-time data sync rather than one-time migrations.
  • Advanced customization requires significant configuration effort, and without dedicated admin resources the tool can become difficult to maintain at scale.

Choosing

Asana logo

Asana

What's pulling them in

  • Organizations with distributed teams cite Asana's multiple project views (List, Board, Calendar, Timeline) as the primary reason for adoption, allowing each team member to work in their preferred interface without changing the underlying data.
  • The platform's 100+ native integrations with tools like Slack, Google Drive, Salesforce, and Microsoft Teams reduce context-switching and keep work synchronized across the stack.
  • Small teams and non-profits value the free plan's generous limits: unlimited projects and tasks for up to 15 team members with basic views, enabling teams to validate fit before committing to a paid tier.
  • Marketing and creative teams specifically praise Asana's visual project organization, reporting dashboards, and timeline views for managing cross-functional campaign workflows.
  • Project managers report that Asana's dependency management and workload views help surface bottlenecks before they derail deadlines.

Object mapping

How OnePlan objects map to Asana

Each row shows how a OnePlan object lands in Asana, including any object-level transformations, lookup resolution, or schema-design dependencies.

Typical mapping — final map is confirmed during the sample migration step.

OnePlan

Plan

maps to

Asana

Project

1:1
Fully supported

OnePlan Plans map to Asana Projects. Plans contain the core metadata (name, description, status, start/end dates) that translates directly to Asana Project fields. We preserve the Plan type hierarchy by organizing Asana Projects into Teams that correspond to OnePlan Areas, and we use Asana's Project Sections to represent sub-plan groupings if the source uses multi-level Work Plan structures within a Plan. OnePlan's Plan-level custom fields map to Asana Project-level custom fields, applied per project from a template.

OnePlan

Work Plan

maps to

Asana

Section or Subproject

1:many
Fully supported

OnePlan Work Plans within a Plan can represent either task groupings or sub-projects. We map Work Plans that contain task lists to Asana Sections within the target Project for lightweight grouping, or to separate Asana Projects if the customer wants independent task assignment and reporting per Work Plan. This choice is made during scoping based on how the customer uses Work Plans for task ownership and progress tracking.

OnePlan

Task

maps to

Asana

Task

1:1
Fully supported

OnePlan Work Plan Tasks migrate to Asana Tasks. OnePlan Estimated Start and Estimated End dates map to Asana Start Date and Due Date. Task dependencies migrate as Asana dependency links (Finish-to-Start only; Asana does not support other dependency types). Note that OnePlan's multiple resource assignments per task must resolve to Asana's single-assignee model; we create one Asana Task per OnePlan task and assign to the primary resource, with additional assignees noted in the task description or a custom multi-user field if the Advanced plan is in use.

OnePlan

Risk

maps to

Asana

Task with custom field

1:1
Fully supported

OnePlan Risks migrate to Asana Tasks tagged with a custom Risk field (Asana Custom Field: Type = 'Risk'). Risk-specific properties (probability, impact, status, owner) migrate as Asana custom fields. Risks do not auto-rollup to a portfolio view in Asana the way they do in OnePlan; we document the risk register as a separate Asana Project or as a tagged view within the main project for the customer's PMO to maintain post-migration.

OnePlan

Issue

maps to

Asana

Task with custom field

1:1
Fully supported

OnePlan Issues migrate to Asana Tasks tagged with a custom Issue field (Asana Custom Field: Type = 'Issue'). Issue properties (severity, status, owner, raised date) map to equivalent Asana custom fields. Like Risks, Issues do not have a native portfolio-level rollup in Asana; we recommend a dedicated Issues project or a tag-based filtered view.

OnePlan

Resource

maps to

Asana

User or Portfolio member

1:1
Fully supported

OnePlan Resources map by email match to Asana Workspace Users. Resource properties (role, department, skill) migrate as Asana custom fields on the User profile or as Portfolio membership attributes. We resolve the resource lookup during import so that task assignments point to valid Asana User records. Resources without a matching Asana User go to a reconciliation queue for the customer's admin to provision.

OnePlan

Time-Phased Resource Plan Data

maps to

Asana

Portfolio Workload section

1:1
Fully supported

OnePlan's resource allocation over time (allocation percentages by period) does not have a native Asana equivalent. Asana's Portfolio Workload view shows tasks assigned to users but does not store time-phased allocation percentages. We migrate the most recent period allocation as a static custom field on the User (e.g., current_allocation_pct) and include a written summary of the full time-phased allocation table for the customer's admin to use with a third-party resource management tool or a custom Asana integration if needed.

OnePlan

Time-Phased Financial Plan Data

maps to

Asana

Custom fields on Project

1:1
Fully supported

OnePlan financial plan data (budget, actuals, forecast by period) migrates to Asana Project custom fields. We map the current period values (budget, actual spend, forecast) as numeric custom fields on the Project. Historical period data is included in a structured CSV deliverable that the customer's finance team can import into a spreadsheet or BI tool. Asana does not natively support financial period tracking; this is a known limitation that we document rather than attempting a partial workaround.

OnePlan

Custom Field (Text, Date, Number, Currency, Yes/No, Choice)

maps to

Asana

Custom Field

lossy
Fully supported

OnePlan's seven custom field types map to equivalent Asana field types. We create Asana custom fields per Project using a migration template rather than from a centralized field library because Asana does not have org-wide custom field configuration. Each project's template defines which custom fields apply. Choice fields migrate as Asana Enum fields with the same options; Yes/No migrates as a Boolean Enum; Currency and Number map directly to Asana Number fields.

OnePlan

Custom Field (User type)

maps to

Asana

User custom field

lossy
Fully supported

OnePlan User-type custom fields (pointing to a Resource) migrate to Asana User custom fields, available on Asana Advanced plan. The User reference resolves to the migrated Asana User record. If the destination Asana plan is Starter or below (no user custom fields), we fall back to a Text field storing the user's name as a string.

OnePlan

Area

maps to

Asana

Team

1:1
Fully supported

OnePlan Areas (top-level organizational units) map to Asana Teams. Each Area becomes a Team in Asana, with the Plans within that Area becoming Projects within the corresponding Team. This preserves the top-level organizational structure from OnePlan while mapping to Asana's permission and sharing model.

OnePlan

Plan Details (form data)

maps to

Asana

Project custom fields

1:1
Fully supported

OnePlan Plan Details form data associated with plans migrates as Asana Project custom fields. Custom form layouts do not migrate; we document the form fields and their values so the customer's admin can recreate the form structure in Asana using a Project template if needed.

Pair-specific challenges

  • OnePlan has no public API for data extraction

    OnePlan does not have a documented public REST API for real-time data extraction. All migration data must be extracted via the OnePlan Migration Tool, which outputs CSV UTF-8 files. We then transform those CSVs and load into Asana using the Asana REST API. This means the migration is a two-step file-based process rather than a direct API-to-API sync, and it requires the customer's OnePlan admin to run the Migration Tool on the source side. If the customer lacks admin access or the Migration Tool has not been configured, extraction scope is limited to whatever data the admin can export manually.

  • OnePlan Migration Tool is append-only

    The OnePlan Migration Tool can only add records and cannot update or delete existing records in OnePlan. For the destination side (Asana), this constraint means pre-existing data in the target Asana environment will not be overwritten by the migration. We must provision a clean Asana target workspace or manually deduplicate before migration runs. We flag this during scoping and advise customers to use a fresh Asana workspace for migration or budget time for deduplication.

  • Asana allows only one assignee per task

    OnePlan's resource assignment model supports multiple assignees per task (resource-based allocation). Asana supports only one assignee per task at all plan tiers. We resolve this by assigning to the primary resource and including secondary assignees as a comma-separated text field or as an Asana User custom field if the Advanced plan is in use. The customer should decide during scoping whether to use a multi-user custom field or to create separate tasks per assignee. This is a structural gap that has no zero-effort resolution.

  • Asana has no org-wide custom field configuration

    OnePlan supports centralized custom field administration per group, where fields are shared across all Plans and Work Plans. Asana scopes custom fields to individual Projects via templates. Fields defined on one project are not automatically available on another. We create a migration template that defines the standard custom fields per project type, but any post-migration addition of a new custom field must be done per project or by applying a project template. This increases ongoing admin effort compared to OnePlan's centralized approach.

  • Financial and resource plan time-phased data has no native Asana home

    OnePlan's time-phased financial and resource allocation data (planned vs actual costs and resource utilization over time) has no native equivalent in Asana. We migrate the most recent period values as static custom fields and deliver the full time-phased history as a structured CSV. Asana does not have a financial planning module, so budget tracking, forecasting, and resource capacity planning must move to a third-party tool or a custom spreadsheet maintained outside Asana. We document this gap in the migration handoff so the customer can plan accordingly.

Migration approach

Six steps for a successful OnePlan to Asana data migration

  1. Source audit and CSV extraction scoping

    We audit the OnePlan source environment: enumerate all Plans, Work Plans, Tasks, Risks, Issues, Resources, Areas, and Plan Details forms. We assess custom field definitions per group and identify which ones are centralized (OnePlan admin-level) versus per-plan. We confirm the customer has OnePlan admin access to run the Migration Tool and extract CSV UTF-8 files. We estimate row counts per entity and flag if any single CSV will exceed the 50,000-row recommendation, which would require chunking. We also verify SharePoint authentication status because the Migration Tool reads from SharePoint or OneDrive, and Microsoft deprecated basic username/password authentication in April 2026.

  2. Target schema design and Asana workspace setup

    We design the Asana destination structure: Teams (mapped from OnePlan Areas), Projects (mapped from OnePlan Plans), Sections (mapped from Work Plans where appropriate), and custom fields per project template. We create the Asana custom fields for Risks, Issues, and financial/resource metadata. If the Advanced plan is in use, we configure User custom fields for multi-user assignments. We set up Asana Portfolio views that roll up Projects by Team for the PMO visibility the customer currently gets from OnePlan portfolios. We document the Asana field IDs that correspond to each OnePlan field for use during import.

  3. CSV transformation and dependency sequencing

    We transform the OnePlan CSV exports into import-ready JSON payloads for the Asana API. We resolve parent-record dependencies: Projects must exist before Tasks can be assigned to them, Sections must exist before Tasks can be placed in them, and Users must exist before Tasks can be assigned. We sequence the CSV batches by these dependencies. We apply the single-assignee resolution for tasks that had multiple OnePlan resources. We map OnePlan task dependencies to Asana dependency links, noting that only Finish-to-Start dependencies are supported in Asana; any other dependency types are dropped with a documented gap in the handoff.

  4. Sandbox validation and record reconciliation

    We run a full migration into a test Asana workspace using production-equivalent data volume. The customer's PMO lead reviews a sample of migrated Projects and Tasks against the OnePlan source, checking custom field values, date accuracy, risk/issue classification, and resource assignments. We reconcile record counts: Plans vs Projects, Tasks vs Tasks, Risks/Issues vs tagged Tasks, Resources vs matched Users. Any mapping corrections (wrong field, missing value, wrong assignee) are documented and applied before production migration. This step typically takes one to two weeks depending on customer review cycles.

  5. Production migration and delta sync

    We run the production migration in dependency order: Teams first, then Projects, then Sections, then Tasks with dependency links, then Risks and Issues as tagged Tasks, then Resources as User custom fields. Each phase emits a row-count reconciliation report. We run a final delta pass to capture any records modified in OnePlan during the migration window. We include a post-migration step requiring the customer's admin to open each migrated Project in Asana and save it, which triggers Asana's internal timeline recalculation (analogous to OnePlan's Estimated Start/End auto-reschedule behavior).

  6. Cutover, validation, and handoff

    We freeze writes to OnePlan during cutover, run the final delta migration, then mark Asana as the system of record. We deliver a migration inventory document covering: custom field mapping table, Stage Gate workflow gap inventory (to rebuild manually or via third-party app), attachment gap statement (documents not migrated), financial data handoff CSV, and resource allocation handoff CSV. We support a one-week hypercare window for reconciliation issues. We do not rebuild Stage Gate workflows, automations, or custom Asana apps as part of the standard migration scope; these are documented separately for the customer's admin or a separate engagement.

Platform deep dives

Context on both ends of the pair

OnePlan logo

OnePlan

Source

Strengths

  • Integrates natively with Microsoft Project Online, Planner, Azure DevOps, Jira, and Smartsheet for broad ecosystem compatibility.
  • Supports hierarchical plan types enabling program/project structures that Project Online does not natively offer.
  • Combines portfolio, resource, financial, and work management in a single platform reducing tool sprawl.
  • CSV-based Migration Tool provides a structured path for one-time data imports with clear templates.
  • Rolling up views across programs and portfolios gives Programme and Portfolio Managers clear visibility without rebuilding spreadsheets.

Weaknesses

  • No public API documented for real-time integrations; teams relying on API access for ongoing sync are not well-served.
  • The Migration Tool only appends data and cannot update or delete existing records, requiring manual pre-cleanup.
  • Schedules imported via the Migration Tool will not auto-reschedule until a user opens and saves the plan in OnePan's UI.
  • Stage Gate workflow configurations are not exportable, forcing teams to rebuild process flows in the destination environment.
  • Document and attachment handling is outside the Migration Tool scope, requiring a separate file migration process.

Destination

Strengths

  • Unlimited projects and tasks on the free plan for teams up to 15 members.
  • 100+ native integrations including Salesforce, Slack, Google Drive, and Microsoft Teams.
  • Four distinct project views (List, Board, Calendar, Timeline) in a single interface.
  • Dependency management with start/end dates and predecessor links for critical path tracking.
  • Portfolio dashboards for executives to track cross-project status and workload.

Weaknesses

  • Per-seat pricing scales expensively: Advanced tier costs nearly double Starter for a 50-seat team.
  • API does not expose all UI-accessible data; some fields require screen-scraping for full fidelity.
  • Automation rule limits on lower tiers are restrictive, causing power users to upgrade or leave.
  • No native document/wiki capability forces teams to use external tools for knowledge management.
  • Rate limits (150 req/min on free, 1,500 req/min on paid) constrain bulk migration throughput.

Most migrations land between three and five weeks for portfolios with up to 50 Plans, 5,000 Tasks, and straightforward custom field schemas. Migrations with hierarchical program structures (Programs containing multiple Projects), large resource allocation histories, or multi-file CSV extraction requiring dependency sequencing move to six to ten weeks. Large portfolios exceeding 50,000 rows per CSV require chunked batch processing and may push timelines beyond ten weeks. The customer review and sign-off cycle on sandbox validation is the most common source of schedule variance.
