Overview

What this migration involves

Moving from Nozbe to Asana is a file-based migration. Nozbe has no public API on its current product, so we run the Nozbe Classic JSON backup export, decompress the archive, and parse the nested structure into flat CSV files. Projects map 1:1 to Asana Projects. Tasks carry their Done state, Priority, and Due Date as Asana fields, and subtasks map one level deep. Comments attach under tasks in Asana with full author and timestamp preservation. Tags map to Asana Tags; GTD Categories map to a custom Tags setup because Asana has no native GTD-context model. Recurring tasks require expansion into individual task instances because Asana does not preserve recurrence rules on imported tasks. We do not migrate Inbox items as a distinct object; we convert them to Asana Tasks in the Inbox view. We do not migrate Nozbe Workflows, Templates, or Business Spaces as code; we deliver a written inventory for your admin to rebuild in Asana.

Why teams make this switch

Two sides of the same decision

Leaving

Nozbe logo

Nozbe

What's pushing teams away

  • Price-to-feature ratio feels high — comparable tools like Asana offer broader project management at similar or lower cost, and Nozbe lacks time tracking, natural language input, and custom themes.
  • No free tier exists, making it difficult for teams to evaluate the product before committing, especially when competitors offer generous free plans.
  • Limited export and API access makes data portability a real concern; users who want to leave find they cannot easily extract their full history including tags, priorities, and recurring task rules.
  • The product split between Nozbe Classic and new Nozbe creates confusion and upgrade friction; some users feel forced into a migration they do not want.
  • Attachment handling is basic — no built-in document management, version history, or rich media preview, causing teams that rely on file attachments to seek alternatives.

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 Nozbe objects map to Asana

Each row shows how a Nozbe 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.

Nozbe

Project

maps to

Asana

Project

1:1
Fully supported

Nozbe Projects map directly to Asana Projects. We extract the project name, color label, completion status, and member visibility from the Nozbe JSON and set these as Asana Project fields (name, color, is_public). Project Groups from Nozbe Classic become Asana Portfolios if multiple related projects need cross-project tracking. Nozbe's private project flag maps to Asana's team-scoped access controls.

Nozbe

Task

maps to

Asana

Task

1:1
Fully supported

Nozbe Tasks map to Asana Tasks. The Nozbe due_date maps to Asana due_on, done (boolean) maps to completed (boolean), priority maps to a custom Priority picklist field since Asana uses a numeric importance/urgency matrix rather than a named priority label, and the task creator maps to the Asana created_by reference. Assignee resolution runs by email match against the Asana workspace User list.

Nozbe

Subtask

maps to

Asana

Subtask

1:1
Fully supported

Nozbe does not have a native subtask object, but Asana supports one level of subtask nesting. If the Nozbe export contains nested task structures (task-within-task), we flatten the hierarchy and map the inner task as an Asana Subtask under the parent. Recursion beyond one level of nesting is not supported by Asana's API and is documented for manual reconstruction.

Nozbe

Recurrence

maps to

Asana

Task (expanded)

1:many
Fully supported

Nozbe stores recurrence as a rule on the Task object. Asana's CSV Import Wizard does not preserve recurrence rules on import. We must expand each recurring task into a series of individual Tasks with explicit due dates. A task with a biweekly recurrence over three years generates 78 individual tasks, which can inflate task counts substantially. We flag this during scoping and offer two paths: expand all recurrences into individual Asana Tasks, or store the recurrence rule as a custom Recurrence_Rule__c text field on the first task instance.

Nozbe

Comment

maps to

Asana

Subtask Comment

1:1
Fully supported

Nozbe Comments are threaded under Tasks as the primary communication mechanism. We preserve the full comment history under each Task in Asana as Subtask Comments (Asana's native comment structure on Tasks). Author email, timestamp, and @mentions carry over. Nozbe file attachments embedded in comments migrate as attachment links in the Asana comment body. Comment ordering by timestamp is preserved by insertion order during the CSV load.

Nozbe

Tag

maps to

Asana

Tag

1:1
Fully supported

Nozbe Tags are a flat label list per workspace and map directly to Asana Tags. The tag name becomes the Asana Tag name. If Nozbe Classic export does not include the full tag list (it is sometimes excluded from the JSON backup), we scrape the workspace tag list from the Nozbe web UI during scoping. We flag any tags not recoverable from either path and recreate them as Asana Tags from task references.

Nozbe

Category

maps to

Asana

Tag (custom label group)

lossy
Fully supported

Nozbe Categories are part of its GTD implementation (e.g., @calls, @home, @work contexts) and have no native equivalent in Asana. We map Categories to Asana Tags using a naming convention (Category name prefixed with @) so that the GTD context is visible and filterable in Asana. Teams relying heavily on Categories should define a consistent naming scheme during scoping because Asana Tags have no native grouping or hierarchy.

Nozbe

Attachment

maps to

Asana

Attachment (comment link)

1:1
Fully supported

Nozbe attachments stored in comments and projects migrate as external URL links attached to the corresponding Asana Task or Subtask Comment. Nozbe Classic export includes attachment URLs. We validate each URL during migration and flag any that return 404 or are no longer accessible. Large binary file uploads (e.g., PDFs over 100MB) may exceed Asana's file size limit and require alternative storage with a link left in the task.

Nozbe

Inbox Item

maps to

Asana

Task (Inbox view)

1:1
Fully supported

Nozbe Inbox is a GTD capture zone for unsorted tasks with no equivalent in Asana. We migrate Inbox items as Asana Tasks placed in the Inbox view without a project assignment, preserving the original capture timestamp. Assignee remains unset on migrated Inbox items because they represent items awaiting GTD processing rather than assigned work.

Nozbe

Team Member

maps to

Asana

User

1:1
Fully supported

Nozbe Team Members are matched to Asana Users by email address during scoping. We generate a member mapping table and invite any matched Asana users to the destination workspace. Members without an existing Asana account are flagged in a reconciliation queue for the customer admin to provision before the final migration phase begins.

Nozbe

Business Space

maps to

Asana

Workspace

1:many
Fully supported

Nozbe Business Spaces (enterprise-only organisational unit in new Nozbe) do not have a direct Asana equivalent because Asana uses a single Workspace per organisation. We map all Business Spaces into one Asana Workspace, using Asana Teams to differentiate business units. If the customer has more than one Business Space and requires strict data separation, we recommend consolidating under one Workspace with Team-scoped access controls.

Nozbe

Project Template

maps to

Asana

Project Template

1:1
Fully supported

Nozbe Project Templates do not migrate to Asana as reusable templates. We document the template structure (project name, default task list, and any default assignees) in a written handoff sheet so the customer's admin can recreate the template in Asana. Template recreation is out of scope for the standard migration engagement.

Pair-specific challenges

  • No public API forces file-based extraction from Nozbe Classic

    New Nozbe has no REST or GraphQL API for external data access. The only supported export path is the JSON backup from Nozbe Classic settings, which downloads a zip archive of Projects, Tasks, Comments, and Attachments. We run the Nozbe Classic export, decompress the archive, and parse the nested JSON into flat CSV for Asana ingestion. If the customer is on new Nozbe without an active Classic account, they must use Nozbe's own Migrator to move data to Classic first, which is a two-step process requiring admin access and a quiet-period window.

  • Tags and Categories require manual reconciliation

    Nozbe Classic's downloadable JSON backup sometimes excludes Tags and Categories. These are not guaranteed to appear in the export file even for active workspaces. We work around this by scraping the tag list from the Nozbe web interface during scoping if the export is incomplete, but this requires the customer to grant temporary read access. If the tag and category list is not recoverable, we recreate labels as Asana Tags from task references and document the gap in the reconciliation report.

  • Recurring tasks generate inflated task counts in Asana

    Nozbe stores recurrence as a rule on the Task object. Asana's CSV Import Wizard does not preserve recurrence rules on import. We must expand each recurring task into a series of individual Tasks with explicit due dates. A biweekly recurrence over three years becomes 78 individual tasks, which inflates task counts significantly and can approach Asana's import row limits on very large datasets. We scope the recurrence expansion during discovery and agree on an approach (expand all, expand N instances, or store the rule as a text field) before migration runs.

  • Completed tasks are capped at 500 per project in Nozbe Classic export

    Nozbe's migrator documentation explicitly states that completed tasks are limited to 500 per project in the exported dataset. Teams with long project histories that accumulated more than 500 completed tasks per project will have those tasks truncated in the export. We flag this gap during scoping by querying the customer's Nozbe data for projects with more than 500 completed tasks and present options: prioritize recent completed tasks, migrate only open tasks, or handle the historical completed-task gap separately.

  • Asana subtasks support only one level of nesting

    Asana's data model supports subtasks to one level of depth only. If the Nozbe export contains multi-level task nesting (a subtask within a subtask), Asana cannot represent the deeper hierarchy natively. We flatten nested tasks beyond one level into sibling subtasks under the same parent and document the flattening in the migration report so the admin can manually reorganise the hierarchy if needed.

Migration approach

Six steps for a successful Nozbe to Asana data migration

  1. Discovery and JSON extraction

    We audit the Nozbe account by running the Nozbe Classic JSON backup export (Settings > Account > Export) and examining the archive contents: project count, task count, completed task volume per project, tag list completeness, and attachment URLs. We identify any completed-task truncation risk (cap of 500 per project), check whether Tags and Categories appear in the export, and count recurring tasks. If the customer is on new Nozbe without a Classic account, we schedule the Classic Migrator step first.

  2. Data transformation and CSV normalisation

    We decompress the Nozbe JSON archive and parse the nested structure into flat CSV files, one per object type: Projects.csv, Tasks.csv, Subtasks.csv, Comments.csv, Attachments.csv, and Tags.csv. We map Nozbe's flat task-comment structure into Asana's task-with-comments model, set task Status to Asana's completed/non-completed enum, and transform Nozbe Priority values into a custom Priority picklist field. For recurring tasks, we either expand into individual rows or record the recurrence rule in a Recurrence_Rule__c text field, depending on the agreed approach.

  3. Member and category lookup resolution

    We extract every distinct Nozbe Team Member email and resolve against the Asana workspace User list. Members without an existing Asana account are flagged in a reconciliation queue for the customer's admin to provision. For Tags, we reconcile against the Asana tag list; missing tags are created before import. For Categories, we agree on a naming convention (e.g., prefix @context labels) and create the corresponding Asana Tags during this phase.

  4. Asana import in dependency order

    We load data into Asana using the Asana Import Wizard (for smaller datasets) or the Asana API (for datasets over 10,000 records), following dependency order: Projects first, then Tasks (with assignee resolution), then Subtasks (with parent task reference), then Comments (linked to tasks by ID), then Attachments (as URL links in comments), then Tags applied to tasks. Each phase emits a row-count reconciliation report and a random-sample validation of 25-50 records against the source Nozbe data.

  5. Cutover, validation, and handoff

    We run a final delta migration of any records modified during the cutover window, then mark the migration as complete. We deliver a written migration report covering record counts by object, any gaps (completed tasks exceeding the 500 cap, unrecoverable tags), and the Asana template reconstruction sheet for any Nozbe project templates. Workflows, automations, and forms do not migrate; we deliver a written inventory of these for the customer's admin to rebuild in Asana. We offer a one-week hypercare window for reconciliation issues raised during the first week of live use.

Platform deep dives

Context on both ends of the pair

Nozbe logo

Nozbe

Source

Strengths

  • GTD-native feature set: Inbox, Categories, Context views, and Priorities built in rather than bolted on.
  • Cross-platform coverage on macOS, Windows, iOS, Android, and web with consistent UX across all surfaces.
  • Task-based communication: comments and discussions live inside Tasks rather than in separate chat or email threads.
  • European data residency with GDPR compliance, run by a Poland-based company founded in 2007.
  • Simple three-layer data model (Projects → Tasks → Comments) makes scoping a migration relatively predictable.

Weaknesses

  • No free tier, limiting evaluation and onboarding for new teams.
  • No documented public API — all data movement must go through Nozbe Classic's limited JSON export or manual CSV workarounds.
  • No time tracking, natural language input, or custom interface themes — features common in competing PM tools.
  • Limited export from new Nozbe; Nozbe Classic export covers only Projects, Tasks, and Attachments, excluding Tags, Categories, and Inbox items.
  • Data portability is a known pain point; users who want to leave face real friction in extracting their full history.

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.

Small migrations under 500 tasks with no recurrence and clean member mapping land in two to three weeks. Medium migrations with 1,000-5,000 tasks, active recurrence patterns, and tag reconciliation move to four to six weeks. Large or multi-workspace Nozbe accounts with complex attachment handling, multiple Business Spaces, and historical completed-task gaps scope to six to eight weeks. Timeline is driven by dataset size, recurrence expansion scope, and how quickly member lookups are resolved in the Asana workspace.
