Overview
Moving from Basecamp to Asana is a structural uplift, not a simple record copy. Basecamp's flat data model has no custom fields, no subtasks, no task dependencies, and no Gantt or Timeline view — Asana has all of these and demands a richer schema to use them. We start by mapping every Basecamp Project to an Asana Project, every To-do List to an Asana Section, and every To-do to a Task with assignee and due date preserved. Hill Chart numeric progress transfers as a custom numeric field so historical momentum data is not lost. Pings (Basecamp's direct messages) are not exportable via API or the built-in ZIP; we flag them for manual export before migration begins. Basecamp's automatic check-ins, document collaborative editing limits, and absence of automation have no equivalent in Asana's feature set, so we deliver a written inventory of these gaps for your team to address post-migration rather than attempting an automated transform that would produce invalid data in Asana.
Every standard and custom field arrives verified.

Object mapping
Each row shows how a Basecamp 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.
Basecamp
Project
Asana
Project
1:1Basecamp Projects map directly to Asana Projects. The project name, description, archived status, and start/end dates migrate. Basecamp's project-level settings (notifications, team visibility) do not have direct Asana equivalents; we set the Asana project to Team-private or workspace-private based on the original Basecamp access level. Multi-workspace Basecamp accounts require separate Asana workspace mapping per Basecamp account.
Basecamp
To-do List
Asana
Section
1:1Basecamp To-do Lists map to Asana Sections within the migrated Project. The list name and ordering within the project are preserved. Asana Sections are grouping containers, not records, so there is no standalone Section API object to create. If a Basecamp To-do List contains only one or two To-dos, we collapse it and assign the To-dos directly to the Project to reduce empty Sections.
Basecamp
To-do
Asana
Task
1:1Basecamp To-dos map to Asana Tasks. Assignee (including unassigned), due date, completion status, notes, and creation timestamp migrate. Basecamp does not support subtasks, so each To-do lands as a single Task with no subtasks. We preserve the original Basecamp record ID as a custom field bc_todo_id__c for audit and reconciliation. Recurring tasks in Basecamp are not a native feature; teams that manually recreate recurring work carry forward the pattern as a note on the migrated Task.
Basecamp
Message Board
Asana
Conversation + Comments
1:manyBasecamp Message Boards hold threads with a title, body, author, timestamps, and nested comments. We split each thread into an Asana Conversation (the top-level post) with attached Comments (the thread replies). The author, body HTML, and timestamps migrate. Message Board ordering within the project is preserved as conversation order. Discussions that reference specific To-dos are cross-linked by bc_todo_id__c in the task note field.
Basecamp
Document (Workdocs)
Asana
Project Brief
1:1Basecamp Documents (Workdocs) are rich-text pages with HTML content, title, author, and creation timestamp. We migrate the full HTML body to an Asana Project Brief. Images embedded in Workdocs are downloaded and re-attached as files on the Project Brief. Basecamp's lack of real-time collaborative editing on Documents means there is no concurrent-edit conflict history to preserve.
Basecamp
Schedule Event
Asana
Task with Start Date and Due Date
1:1Basecamp Schedule events carry a title, start datetime, end datetime, all-day flag, assigned person, and optional notes. We map these to Asana Tasks with Start Date and Due Date set from the Basecamp schedule range, and the assignee migrated from the Basecamp person field. Recurring schedule items in Basecamp (daily, weekly, monthly patterns) are documented as a note on the migrated Task and recommended for recreation in Asana's recurring task feature post-migration.
Basecamp
Hill Chart
Asana
Custom numeric field on Task
1:1Hill Charts are unique to Basecamp and store only a numeric progress value (0-100) per To-do. The curved Hill Chart visualization cannot be exported. We extract the numeric value and set it as a custom numeric field named Hill_Progress__c on each migrated Task. The customer should not treat this as a real progress percentage; it is a continuity marker so reviewers can see which tasks had momentum data in Basecamp.
Basecamp
Attachment
Asana
Attachment on Task, Conversation, or Project Brief
1:1Files attached to To-dos, Messages, or Documents in Basecamp are downloaded using the Basecamp Classic API with the stored download URL. Each file is then attached to the corresponding migrated record in Asana (Task, Conversation, or Project Brief) via the Asana Attachments API. Files larger than 100 MB are flagged for chunked upload or alternative delivery. Basecamp's attachment filename and original upload date are preserved in the Asana metadata.
Basecamp
Comment
Asana
Comment on Task or Conversation
1:1Comments attach to To-dos, Messages, and Documents in Basecamp. We preserve the comment text, author email, and timestamp, and attach them to the corresponding migrated parent record in Asana (Task or Conversation). Nested comment threads in Basecamp's Message Boards are flattened into the Conversation's comment sequence. Comment authorship is mapped via email to the Asana user; any unmapped author is added as a comment note attributing the original Basecamp author.
Basecamp
User and Membership
Asana
User and Project membership
1:1Basecamp charges per internal employee, not per guest. We map internal Basecamp users by email to Asana Users. Guests (clients and contractors who do not count toward Basecamp billing) are flagged during scoping and mapped to Asana project membership as Guests if the destination Asana workspace has Guest access enabled, or held in a reconciliation queue if Guest access is not configured. User role within the project (Admin, Normal, Guest) is not directly migratable; we set all migrated members as Normal access and document the original role assignments for manual update.
Basecamp
Project Template
Asana
Project Template
lossyBasecamp Project Templates store the structure of a Project (To-do Lists, scheduled items, and initial messages) but are not accessible via the Basecamp Classic API. We cannot programmatically export template contents. During scoping we identify which Basecamp Projects are templates, export their structure via the UI bundle, and replicate them manually as Asana Project Templates. The customer should verify the recreated template structure before using it for new projects.
Basecamp
Automatic Check-in
Asana
No direct equivalent
lossyBasecamp's automatic check-ins are scheduled questions sent to team members on a daily or weekly cadence with responses posted to the project. Asana has no equivalent native feature. We document each active check-in (question text, frequency, recipient group) as a written inventory item. Replacement options include Asana Rules with scheduled triggers and Slack integration, or a third-party check-in tool, which the customer's admin selects post-migration.

Basecamp gotchas
Built-in export produces a ZIP with no import path back in
Pings (direct messages) are not exportable
Hill Chart progress is proprietary and non-reproducible
No subtasks means deeply nested work is lost if the destination supports them
Project Templates are not API-accessible
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 scope audit
We audit the source Basecamp account across projects, To-dos, To-do Lists, Message Boards, Documents, Schedule events, and attachments. We capture total record counts per object, identify guest and internal user roles, flag Projects used as templates, list active automatic check-ins, and identify any Projects that are archived. We also confirm whether the destination Asana workspace already exists or requires provisioning, and whether Guest access is enabled. The discovery output is a written migration scope, record count summary, and a checklist of non-migratable items (Pings, templates, check-ins) requiring manual action before cutover.
Schema design and custom field pre-creation
We design the Asana destination schema before any data moves. This includes pre-creating custom fields (Hill_Progress__c as numeric, bc_todo_id__c as text, bc_list_name__c as text) in the target workspace or project, setting up any Asana Teams needed to match Basecamp project membership, and configuring Guest access settings if external collaborators are in scope. We also create Asana Project Templates for any Basecamp Projects identified as templates during discovery, so the customer can use them immediately post-migration.
Sandbox migration and reconciliation
We run a full migration into a staging Asana workspace using production-like data volume. The customer's project manager or admin reviews the migrated Projects, spot-checks To-do completeness, verifies that Message Board threads are readable, confirms attachment filenames are present, and validates that Hill Chart numeric values appear in Hill_Progress__c. Any mapping corrections are documented and applied to the production migration plan. Sandbox reconciliation typically takes two to three days and is required before production cutover.
User reconciliation and Asana workspace provisioning
We extract every distinct Basecamp user email from Projects, To-dos, Schedule events, and Message Boards. We match by email against the destination Asana workspace User list. Internal users (employee accounts) are mapped directly. Guests (clients, contractors) are flagged and require the customer's admin to either enable Guest access in Asana or manually reassign their tasks to internal team members. Any Basecamp user with no Asana match goes to a reconciliation queue for manual provisioning before production migration begins.
Production migration in dependency order
We run production migration in record-dependency order: Users (manually provisioned, validated), Projects (as containers), Sections (from To-do Lists), Tasks (from To-dos with custom fields and assignees), Conversations (from Message Board threads with comments), Project Briefs (from Documents with inline images as attachments), Schedule tasks (from calendar events), and standalone Attachments (linked to parent records by bc_todo_id__c lookup). Each phase emits a row-count reconciliation report. We pause writes to Basecamp during the production migration window to prevent delta records from accumulating.
Cutover, validation, and automation inventory handoff
We freeze Basecamp writes during cutover, run a final delta pass for any records modified during the migration window, then enable Asana as the system of record. We deliver the automation and check-in inventory document listing every automatic check-in, its question text and frequency, and a recommended Asana Rule or third-party replacement. We support a three-day hypercare window where we resolve any reconciliation issues raised by the project team. We do not rebuild automatic check-ins, scheduling patterns, or recurring task logic inside the migration scope; those are documented for your admin to configure post-migration.
