Overview
Birdview is a Professional Services Automation platform with hierarchical Spaces, Projects, Activities, Time tracking, Expense management, Rate cards, and role-based access across Full User, Collaborator, Executive, and Viewer types. Trello is a card-based project management tool built around Workspaces, Boards, Lists, and Cards with no native time tracking, expense management, portfolio views, or approval workflows. This migration narrows scope from PSA to core task management. We map Birdview Activities (Tasks, Issues, Requests) to Trello Cards with the Activity type preserved as a custom field label, export Time Entries as custom number fields or checklist notes, and deliver a written Workflow inventory with Butler rebuild instructions rather than migrating automation as code. The 0:01-hour minimum enforced on Birdview time entries is flagged before migration so the customer can decide whether to carry minimum entries into Trello or handle zero-value records outside the migration.
Every standard and custom field arrives verified.
AI proposes the map; you confirm before any record moves.
Parent–child, lookups, and ownership stay linked.
Calls, emails, meetings — with original timestamps.
Documents, uploads, and inline notes move with the record.

Object mapping
Each row shows how a Birdview object lands in Trello, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Birdview
Space
Trello
Workspace + Board
1:manyBirdview Spaces are the top-level organizational container and can hold child Projects and sub-Spaces. Trello has Workspaces at the top level and Boards as the primary project container. We map each Birdview Space to a Trello Workspace and each direct child Project to a Board within that Workspace. Sub-Spaces are mapped to additional Boards or to Lists within the parent Board depending on the customer's preference documented during scoping. The Workspace name comes from the Space name; the Space description becomes the Workspace description.
Birdview
Project
Trello
Board
1:1Birdview Projects carry status, start and due dates, budget, and owner assignment. We map Project to Trello Board directly, preserving Project name as Board name, Project description as the Board description, and Project status (Active, On Hold, Complete) as Labels on the Board or as a custom field. Owner assignment maps to Board membership in Trello. Dates migrate as custom Date fields on the Board since Trello does not natively track project-level dates.
Birdview
Activity (Task, Issue, Request)
Trello
Card
1:1Birdview Activities are the umbrella term for Tasks, Issues, and Requests, distinguished by an Activity type property. We map all three subtypes to Trello Cards. The Activity type label (Task, Issue, or Request) is preserved as a custom Dropdown field on the Card so the subtype is visible without opening the card. Issue-specific priority and resolution fields migrate as custom Dropdown fields; Request-specific intake form data migrates field-by-field based on the custom form schema enumerated during discovery.
Birdview
Portfolio
Trello
Board Grouping or Label
lossyBirdview Portfolios group Projects for executive-level oversight and are available on Enterprise. Trello has no native portfolio concept. We map Portfolio membership to a custom Dropdown field on each Card (set to the Portfolio name) or to a Label color assigned to all Cards within Portfolio-grouped Boards. The customer chooses the grouping strategy during scoping. Portfolio hierarchy (if multi-level) is flattened to a single Portfolio name field; hierarchy itself cannot be preserved in Trello without a manual folder structure outside the tool.
Birdview
Time Entry
Trello
Card Custom Field or Checklist
1:1Birdview Time Entries are linked to Activities and Users with a minimum 0:01-hour enforcement. We extract every time-entry record and evaluate whether to carry it into Trello. Option A: migrate hours as a custom Number field on the Card, with the 0:01-hour minimum flagged for each record so the customer can accept or discard the entry. Option B: place time entry details in a card Checklist titled 'Time Log' with the hours and user as checklist items. Option C: document all time entries in a CSV export delivered alongside the migration for use in an external billing tool. We recommend Option A or C for teams that need billing reconciliation; Option B for teams tracking effort only. Open time-entry approval records at migration time are flagged as open items for the customer to resolve before cutover.
Birdview
Expense
Trello
Card Description or Separate List
1:1Birdview Expenses are tied to Activities and Projects with optional approval workflows on Enterprise. Trello has no native expense object. We extract expense records as structured data (amount, cost center, date, approval status) and map them to Card custom fields (Amount as Number, Cost Center as Dropdown, Status as Text) or to a dedicated 'Expenses' Card within each Project Board. Approval workflow status is preserved as a Text field; pending approvals at migration time are flagged as open items documented in the migration inventory. Expense approval workflows (Enterprise) do not migrate as automation; they are delivered as a written configuration guide for Butler rebuild.
Birdview
Custom Field
Trello
Custom Field
1:1Birdview custom fields are tenant-defined and can exist on Projects, Tasks, and Activities. Trello supports custom fields per board in five types: Checkbox, Date, Dropdown, Number, and Text. During discovery we enumerate all Birdview custom field definitions and map each to the nearest Trello-equivalent type. Fields with types not supported by Trello (e.g., formula, multi-user, currency with formatting) are documented as Text fields with the raw value preserved. Custom field names are truncated to 25 characters per Trello's limit. Board-level custom fields must be created in each destination Board before Card import; we do this in batch during the setup phase.
Birdview
User Type
Trello
Workspace Member or Guest
1:1Birdview has four user types: Full User, Collaborator, Executive, and Viewer. Trello has Workspace members (full access to Boards they are members of) and Workspace guests (limited to specific Boards). We map Full User and Executive to Workspace members, and Viewer to Workspace guest. Collaborator access (restricted financial data visibility) has no direct Trello equivalent since Trello does not have a financial data layer. We document the Collaborator access scope for each user so the customer's admin can decide whether to grant standard member access or restrict Board membership post-migration.
Birdview
Approval
Trello
Card Checklist (pending) + Documentation
lossyBirdview Approvals are tied to expense and time-entry workflows on Enterprise and store approval history. Trello has no native approval object or approval routing. We convert open approvals at migration time into Cards with a Checklist titled 'Approval Required' listing the approver and approval criteria, and deliver the full approval history as a documentation record. Closed approval history (audit log) is delivered as a CSV. Approval routing automations are not migratable and are documented for Butler rebuild.
Birdview
Rate Card
Trello
Card Description or Power-Up Field
lossyBirdview Rate Cards define billing rates per user or role and are available on Enterprise. Trello has no native rate card concept. We extract rate card definitions and map them to Card descriptions on a designated 'Rate Card Reference' Card within each Project Board, or document them as a structured CSV alongside the migration. Role-based rate cards require user-to-role mapping; we deliver this mapping as a configuration note. Rate cards do not migrate as automation and cannot be enforced in Trello without a third-party Power-Up.
Birdview
Workflow
Trello
Butler Documentation
lossyBirdview Workflows govern task routing, status transitions, and approval triggers on Enterprise. Trello automates through Butler (board-level commands and triggers) and Power-Ups. We do not migrate Workflows as code. We enumerate every active Birdview Workflow with its trigger conditions, routing rules, and actions, and deliver a written Butler rebuild guide that maps each Workflow to equivalent Butler commands or Power-Up configurations. The customer's admin implements the Butler rebuild post-migration. Workflow documentation is scoped to active workflows; archived or inactive workflows are noted but not documented for rebuild.
Birdview
Attachment + Comment
Trello
Card Attachment + Card Comment
1:1Birdview Activity attachments migrate to Trello Card attachments. We resolve the parent Card for each attachment by matching the source Activity ID to the migrated Card. Comments on Birdview Activities migrate as Trello Card comments with the original author and timestamp preserved. Attachments are processed in a separate batch phase after Cards are created because Trello API handles attachments with a lower rate limit than Card creation. If any Birdview attachment exceeds Trello's 10 MB per-file limit, we flag the file and deliver it as a shared download link instead.

Migration approach
Discovery and API access validation
We audit the Birdview tenant across Spaces, Projects, Activities, Activity types (Task, Issue, Request), Portfolios, Time Entries, Expenses, Custom Fields, User types, active Workflows, and open Approvals. We validate Birdview API access and document the per-user rate limits that apply during extraction. We enumerate every custom field definition (name, type, applied object) before any field-level mapping begins. The discovery output is a written migration scope document listing every object, its record count, and the mapping decision for each.
Trello Workspace and Board scaffolding
We create the Trello Workspace structure based on the Birdview Space hierarchy, creating one Workspace per top-level Space and one Board per direct child Project. We create all required custom fields (per type, per Board) in batch before any Card import begins, truncating names to 25 characters and mapping Birdview field types to Trello's five supported types. We map the 0:01-hour floor on time entries and confirm the customer's choice (carry minimum, drop, or external reconciliation) before extracting time entry data. We also create the Rate Card Reference Card in each Project Board at this stage.
Data extraction from Birdview
We extract all data objects in dependency order: User types and owner mapping first, then Spaces and Projects, then Activities (Tasks, Issues, Requests), then Time Entries and Expenses, then custom field values, then attachments and comments. Workflow definitions are extracted as configuration documentation rather than data. Approval history is extracted as a log record. We flag any Birdview record that is archived, soft-deleted, or pending approval at this stage so the customer can confirm scope before extraction completes. We handle the minimum 0:01-hour floor during extraction by marking affected time entries for customer decision.
Transformation and Activity type preservation
We transform extracted Birdview records into Trello Card format. Activities receive the Activity type as a custom Dropdown field (Task, Issue, or Request). Issues and Requests retain their additional properties (priority, resolution, intake form fields) as custom fields on the Card. Portfolios are flattened to a custom Dropdown or Label applied to each Card. Time entries are transformed per the customer's chosen strategy (custom Number field, Checklist, or external CSV). Expenses are structured as card custom fields or as a dedicated expense Card within each Project Board. We resolve owner email to Trello Workspace member by matching against the User provisioning list created during discovery.
Card import with attachment batch
We import Cards into Trello in dependency order (Projects first as Boards, then Activities as Cards with parent Board resolved). Custom field values are set after Card creation because Trello API requires the Card to exist before custom field values can be written. Attachments and comments are imported in a separate batch after all Cards exist, using Trello API's lower attachment rate limits. Each batch emits a row-count reconciliation report comparing extracted count to imported count. Any records that fail import are logged with the API error and retried once before being escalated to the customer for manual resolution.
Workflow documentation and cutover
We deliver the written Workflow inventory and Butler rebuild guide as a structured document mapping each Birdview Workflow trigger, condition, and action to an equivalent Butler command or Power-Up configuration. Approval routing documentation is delivered separately. We freeze Birdview writes during the cutover window, run a final delta extraction for any records modified during the migration window, then mark the migration complete. We validate record counts across Spaces, Projects, Activities, and Time Entries against the discovery baseline. We do not configure Butler automations or provision Power-Ups as part of the standard migration scope; these are documented for the customer's admin to implement post-migration.
