Overview
Trigger has no documented public API, so every migration relies on manual CSV exports from five separate views (Clients, Projects, Tasks, Time Entries, Invoices). We download all views within a single session to minimize desynchronisation, then run a multi-step join by internal ID to reconstruct relationships like task-to-project and time-entry-to-task. The most significant schema gap is invoicing: Trigger invoices are derived from billable time entries, but Asana has no native billing or invoicing feature, so we flag this limitation during scoping and migrate invoice metadata as a written record rather than a live object. Time entries require a custom-field workaround because Asana has no native time-tracking object. We do not migrate automation rules, forms, or client portals as code; we deliver a written inventory for your admin to rebuild using Asana Rules and Forms.
Every standard and custom field arrives verified.

Object mapping
Each row shows how a Trigger 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.
Trigger
Client
Asana
Team
1:1Trigger Clients map to Asana Teams, which serve as the organisational unit for each client relationship. We extract the client slug or name and create a corresponding Asana Team, preserving the client email domain as a naming reference. User membership in the Asana Team maps to the list of Trigger users who were assigned to that client's projects. Projects and tasks in Trigger are imported as Asana Projects and Tasks belonging to the corresponding Team, providing the project-to-client linkage that Trigger maintains natively.
Trigger
Project
Asana
Project
1:1Trigger Projects map directly to Asana Projects. The project name, status (active, archived), start and due dates, project manager assignment, and hourly budget cap migrate as typed fields. The Trigger client association maps to the Asana Team membership, so the project appears under the correct Team. Archived or locked projects are flagged during scoping and imported as inactive Asana projects with a status custom field to preserve the audit trail without cluttering active workspaces.
Trigger
Task
Asana
Task
1:1Trigger Tasks map to Asana Tasks with name, assignee (resolved by email to the Asana User), priority, status, due date, and estimated hours preserved. Subtasks are nested under their parent task in Trigger; we extract the full hierarchy during the CSV export phase and reconstruct parent-child relationships in Asana using subtask nesting. Trigger task sections map to Asana Sections within the project, maintaining the grouping logic that teams rely on for work organisation.
Trigger
Subtask
Asana
Subtask
1:1Trigger subtasks nested under tasks are extracted as discrete records during the CSV join phase and imported as native Asana subtasks under their parent task. The parent task GID is resolved at import time so that the subtask-to-parent relationship is established immediately on insert rather than requiring a second pass. Assignee, due date, priority, and estimated hours on the subtask carry over, and any custom fields applied to the subtask in Trigger are created in Asana before the subtask import phase begins.
Trigger
Time Entry
Asana
Task (via custom workaround)
lossyAsana has no native time-tracking object, so Trigger time entries require a configuration workaround. We create a dedicated Asana project named 'Time Logs' with custom fields for duration (number), entry date (date), billable flag (checkbox), associated project (text lookup), and associated task (text lookup). Each Trigger time entry becomes a Task in this project with the custom fields populated. Billable time entries in Trigger also link to a Trigger Invoice; we document the total billable amount and associate it with the original project as a note for the customer's team to reconcile in Asana's workload view or a connected billing tool.
Trigger
Invoice
Asana
Not applicable
lossyTrigger invoices are derived objects: the line items are computed from billable time entries rather than stored as discrete records. Asana has no native invoicing or billing feature at any pricing tier. We do not create invoice records in Asana because there is no target object. Instead, we extract invoice metadata (client, project, total amount, status, and date) and invoice line items (derived from billable time entries) and deliver them as a structured CSV inventory. The customer reviews this inventory during the handoff and rebuilds invoices in their preferred billing tool (QuickBooks, FreshBooks, or a custom Asana-connected workflow) using the CSV as a reference. This limitation is documented in the Scope section of the migration agreement before work begins.
Trigger
User
Asana
User
1:1Trigger Users map to Asana Users by email address, which serves as the dedupe key for owner resolution. The Trigger role (admin or member) maps to Asana team membership and permission level: admin users are granted Team Admin in their respective Asana Teams. The hourly rate from Trigger migrates as a custom field on the Asana User profile for use in project budget calculations or time-tracking reconciliation. Any Trigger user without a matching email in the destination Asana organisation is held in a reconciliation queue for the customer's admin to provision the account before record import resumes.
Trigger
Custom Field
Asana
Custom Field
lossyTrigger custom fields on projects and tasks are exported with their field definitions and values. We create the corresponding custom fields in Asana before any data import, matching field types (text, number, date, single-select, multi-select, checkbox) as closely as possible. Trigger formula fields, conditional fields, and rollup calculations have no direct Asana equivalent and are flagged during scoping; we document the field definition and its output value as a static text custom field in Asana so the historical value is preserved even if the calculation logic cannot be replicated.
Trigger
Project Section
Asana
Section
1:1Trigger project sections grouping tasks within a project map directly to Asana Sections within the corresponding project. Section names, ordering, and the task membership within each section carry over as part of the task import phase. Trigger's section-level project manager assignment is not a native Asana concept; we document it as a custom field note in the migration handoff if it was actively used.
Trigger
Task Comment
Asana
Story (Task comment)
1:1Trigger task comments export from the task CSV view and map to Asana Task Stories, preserving the comment text, author (resolved by email to Asana User), and timestamp. Comment ordering is preserved by setting the created_at timestamp on the Asana story to match the original Trigger comment date. Any rich text formatting in Trigger comments that is not natively supported in Asana Stories is simplified to plain text during the import phase to prevent rendering issues.
Trigger
Attachment
Asana
Attachment
1:1Trigger file attachments stored within tasks and projects are not accessible via a public API. We extract the file names, URLs, and associated task or project references from the Trigger export CSVs and deliver a written file inventory. The customer downloads each file from Trigger manually (or using a browser-based bulk download if available) and re-uploads them to the corresponding Asana task or project. Any file exceeding Asana's 100MB per-attachment limit is flagged in the inventory for manual handling. This limitation is disclosed in the pre-migration scoping call and documented in the handoff report.
Trigger
User Role and Hourly Rate
Asana
Team Membership + Custom Field
lossyTrigger user roles (admin or member) and hourly rates are separate from the core user record. Admin status in Trigger maps to the Team Admin permission in the corresponding Asana Team; standard members map to Member. The hourly rate migrates as a number custom field on the Asana User profile named 'Hourly Rate (from Trigger)' for use in budget tracking or billing reconciliation. Rate values are preserved as numeric floats to two decimal places.

Pair-specific challenges
Migration approach
Scoping call and CSV export coordination
We conduct a scoping call to audit the Trigger workspace: project count, task volume, time entry count, custom field definitions, user list, client list, and invoice history. We provide the customer with a written CSV export checklist specifying the five views to export (Clients, Projects, Tasks, Time Entries, Invoices) and the instruction to complete all exports in a single browser session to minimise desynchronisation. We review the export files during the call and flag any structural issues, empty fields, or missing relationships before committing to a timeline.
CSV multi-step join and relationship reconstruction
Trigger exports multiple related entities as separate flat CSV files without foreign key labels in each row. We run a multi-step join by matching internal Trigger IDs across the exported files: task rows include a project ID that we resolve to the project name; time entry rows include a task ID that we resolve to the task name and project. Invoice line items are computed from the billable flag on time entries and joined to the invoice header. The output of this phase is a set of denormalised CSVs with resolved relationship names rather than raw IDs, ready for Asana's CSV importer or API ingestion. We run a row-count reconciliation across all five original exports before this phase begins and again after join completion to confirm no records were dropped.
Asana workspace setup and schema pre-creation
Before any data lands in Asana, we configure the destination workspace: create Teams matching Trigger Clients, set up Projects with Sections mirroring Trigger's project-to-section hierarchy, create custom fields matching Trigger's field definitions in type and name, and configure user accounts. We disable Asana email notifications organisation-wide during the migration window to prevent team inboxes from being flooded with task-assignment notifications. If the customer uses Asana's free or Starter tier, we confirm that the planned custom field count and project structure are within tier limits before proceeding.
Proof-of-migration with a sample dataset
We run a proof-of-migration using a representative sample of approximately 50 records (one or two Trigger projects and their associated tasks, users, and time entries) into a clean Asana test workspace. We validate that project-to-client linking via Team membership is intact, that subtask hierarchy reconstructs correctly, that time entries appear in the dedicated Time Logs project with all custom fields populated, that custom field types map without data loss, and that user resolution by email produces the correct Owner assignments on tasks. The customer reviews the test output and signs off on the mapping logic before we proceed to full production migration.
Production migration in dependency order
We run production migration in this order: Users and Teams (Teams created first so project assignments can reference them), Projects (with Team membership set during creation), Tasks with subtask hierarchy (parent tasks inserted first, then subtasks referencing the parent GID), Task comments (Stories), Time entries (into the dedicated Time Logs project with project and task references as custom fields), and finally a file attachment inventory (file names and task associations exported as a CSV for manual re-upload). We reconcile row counts after each phase before advancing. The migration user is granted Asana admin-level access during the migration window and revoked afterward.
Cutover, handoff, and rebuild inventory delivery
We freeze the Trigger workspace for writes at the agreed cutover date. Any records modified between the last migration pass and cutover are delta-migrated in a final pass. We deliver the migration handoff package: a row-count reconciliation report (source vs destination per object), the invoice metadata CSV (for the customer's billing tool rebuild), the file attachment inventory (with manual re-upload instructions for files under 100MB and flagging for files exceeding that limit), and the automation and form inventory listing every Trigger automation rule and form that requires manual rebuild in Asana Rules or Asana Forms. We support a one-week hypercare window for reconciliation issues raised by the team during their first week of Asana-only operation.
