Overview
Moving from AceProject to Asana is a data-centric migration that preserves your historical project structure, task assignments, and time tracking while taking advantage of Asana's active development, broader integration ecosystem, and more responsive interface. AceProject structures work under a Project with Tasks holding Assignees, Dependencies, Estimates, and Custom Fields; we map those to Asana Projects, Tasks, and custom fields. Subtasks are reconstructed as nested Asana tasks. Time entries and Expenses carry over as task-level custom fields or notes since Asana does not have native time tracking or expense objects. Document metadata migrates as file attachment references. Task dependencies map to Asana dependencies, though teams should note Asana's known limitation where dragging a milestone does not always cascade date changes correctly across all dependent tasks. We do not migrate AceProject workflows, expense approval rules, or built-in reports — we deliver a written inventory of these for your admin to rebuild in Asana.
Every standard and custom field arrives verified.

Object mapping
Each row shows how a AceProject 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.
AceProject
Project
Asana
Project
1:1AceProject Projects map directly to Asana Projects. The project name, description, status, start date, and due date transfer as standard Asana project fields. Custom project-level fields in AceProject map to Asana custom fields created on the project before migration. We preserve the project hierarchy if the account uses parent-child project grouping.
AceProject
Task
Asana
Task
1:1AceProject Tasks map to Asana Tasks within the corresponding project. Assignee, due date, start date, estimated hours, priority, status, and description transfer directly. Task description migrates as the Asana task description field. Custom task fields in AceProject (Boolean, Date, List, Numeric, Text, User types) require pre-creation of equivalent Asana custom fields; we create these before the task import phase and map values by field name.
AceProject
Subtask
Asana
Subtask (nested Task)
1:1AceProject Subtasks nested under Tasks map to Asana subtasks (tasks with a parent_task reference). We flatten the AceProject tree structure during export and reconstruct it in Asana using the parent Task GID as the parent reference. Nested subtasks (sub-subtasks) map to Asana subtasks with their direct parent as the parent_task.
AceProject
User
Asana
User (member of project)
1:1AceProject Users map to Asana Users by email address. We export all user records including name, email, and user-level custom fields. Post-import, we add each migrated user to the corresponding Asana project as a member. Note: Asana's free tier restricts project member counts, so we flag the destination Asana plan during scoping if the project has more than 15 members on a free or Starter plan.
AceProject
Dependency
Asana
Dependency
1:1AceProject Task dependencies map to Asana Dependencies. We export the dependency type (finish-to-start, start-to-start, etc.) and the linked Task ID, then create Asana dependency records with the correct blocking and blocked task references. Teams should note that Asana has documented limitations where dragging a milestone task does not always cascade date changes correctly to all downstream dependent tasks.
AceProject
Time Entry
Asana
Custom Field or Note
lossyAceProject Time Entries record hours, dates, billing rates, and task association. Asana has no native time tracking object in its core PM platform — time tracking requires the optional Asana Time Tracking add-on or a third-party integration. We migrate time entry data as a custom multi-value field (Date + Hours + Notes) on the corresponding task, or as a task note if custom fields are not preferred. The customer chooses the format during scoping.
AceProject
Expense
Asana
Custom Field or Note
lossyAceProject Expense records include amount, category, currency, date, and task association. Asana has no native expense object. We migrate expense data as a custom multi-value field on the task or project, preserving amount, category, and date. Expense approval workflows and per diem rules do not migrate; these are documented as part of the automation inventory.
AceProject
Document
Asana
Attachment (file reference)
1:1AceProject Documents store files attached to Projects or Tasks with version history. We export document metadata (filename, upload date, uploader, version) and file reference URLs. File content transfer depends on whether AceProject hosts the files or links to external storage. If files are hosted in AceProject, we download them and re-upload to Asana as project or task attachments. If AceProject links to external URLs, we preserve the URL as a link attachment.
AceProject
Custom Field (Task)
Asana
Custom Field
1:1AceProject task custom fields support Boolean, Date, List, Numeric, Text, and User types. These map to Asana custom fields of equivalent type. List fields become Asana Dropdown; Boolean becomes a Checkbox (custom field) or a single-select with Yes/No options. User-type fields in AceProject map to Asana People fields. All destination custom fields must exist in Asana before task import begins; we create them during the schema pre-creation phase.
AceProject
Custom Field (User)
Asana
User Custom Fields
1:1AceProject User-level custom fields migrate as key-value pairs. Asana User profiles support custom fields in the Profile section. We map text, date, and list custom fields to their Asana equivalents. Numeric and Boolean fields map to Number and Checkbox user custom fields respectively. User custom fields in Asana are workspace-level and appear on all user profiles.
AceProject
Comment
Asana
Comment
1:1AceProject document and task Comments migrate to Asana task Comments. We export comment text, author, and timestamp. Comment threading in AceProject is flattened during migration — nested replies become top-level comments in Asana ordered by timestamp. Rich text formatting in AceProject comments is simplified to plain text or basic HTML-safe formatting in Asana comments.
AceProject
Workflows and Email Reminders
Asana
Rules (Asana)
lossyAceProject email reminders and basic task notification workflows do not migrate as automation code. We audit every active workflow and email reminder configuration and document it as a written inventory with trigger, conditions, and action details. This inventory is handed to the customer for rebuild in Asana Rules (available at Premium and above) or Asana's advanced automation features. Workflow rebuild is outside standard migration scope.

AceProject gotchas
Task import does not auto-assign users to Projects
Custom fields only visible in the new interface
CSV import requires DOS-style CRLF line endings
Expense field visibility gated by user role
Asana gotchas
Automation rules have no export representation
API rate limits cap bulk migration throughput
Portfolios are view-only objects that do not hold data
Custom field enum options cannot be updated via API
Subtasks do not appear in project views by default
Pair-specific challenges
Migration approach
Discovery and source audit
We audit the AceProject account via the admin Export Data tool across all projects, tasks, subtasks, users, time entries, expenses, documents, and custom fields. We identify which interface version (classic or new) the account uses to confirm custom field value completeness. We extract dependency chains and flag any dependency cycles. We document active workflows, email reminder configurations, and expense approval rules for the automation inventory. The discovery output is a written migration scope with record counts, custom field inventory, and dependency graph summary.
Asana workspace setup and custom field pre-creation
We create the destination Asana workspace, configure project structure, and pre-create all custom fields before any data import. This includes custom fields for AceProject task custom fields (mapped by type), user custom fields, and placeholder fields for time entries and expenses if the customer selects the custom field format. Projects are created in Asana in the same hierarchy as the AceProject source. We create Asana dependencies for the task import scope during this phase so that the dependency graph is ready when tasks land.
User migration and project membership
We migrate AceProject Users to Asana Users by email address. All migrated users are added to their corresponding Asana projects as members before task import begins. If the destination Asana plan has member limits (e.g., 15 members on the free plan), we flag this during scoping and recommend upgrading before migration. We validate that each user's email address exists in Asana or can be provisioned by the customer's admin.
Task and subtask import with dependency resolution
We import AceProject Tasks into Asana Projects using Asana's bulk import API, preserving assignee, due date, start date, description, and custom field values. Subtasks are imported as nested tasks with parent_task references resolved to the migrated parent task's Asana GID. Dependencies are created as Asana dependency records after parent task GIDs are confirmed. We run import in batches to handle rate limits and use exponential backoff on API throttling responses. Each batch emits a row-count reconciliation report.
Time entries, expenses, and document metadata
Time entries and expenses are migrated as custom field values (multi-value Date + Hours or Amount fields) on the corresponding tasks, or as structured task notes if the customer did not select custom fields. Document metadata is imported as Asana attachment references or link attachments. If AceProject files are hosted locally in AceProject, we download and re-upload to Asana. We validate attachment count and file size limits against the destination Asana plan's storage allocation.
Cutover, validation, and automation inventory handoff
We freeze AceProject writes during cutover, run a final delta migration of any records modified during the migration window, then enable Asana as the system of record. We validate record counts across Projects, Tasks, Subtasks, Users, and Attachments against the source. We deliver the automation inventory document covering all AceProject workflows, email reminders, and expense approval rules to the customer's admin for rebuild in Asana Rules or Asana's advanced automation features. We support a one-week hypercare window where we resolve any data quality issues reported by the team.
