Overview
Moving from Pegasus Systems to Trello is a platform-type shift: Pegasus is an agency management suite with integrated project operations, financial management, and client tracking; Trello is a Kanban-style board tool that organises work as Cards inside Lists on Boards. There is no financial module in Trello, no native time-tracking, and no client management object, so Invoices, Expenses, Timesheets, and Clients from Pegasus do not map to native Trello objects. We extract Pegasus data via direct file export or Excel templates (Pegasus has no documented public API), structure the exported Jobs and Tasks into Trello Boards and Cards, and flag any records that require a separate accounting or CRM tool post-migration. Archived Cards require restoration in Pegasus before export because Trello's native import excludes archived content. We do not migrate automations, workflow templates, or reporting configurations from Pegasus; these require rebuild in Trello Butler or a documented handoff to the customer's admin.

Object mapping
Each row shows how a Pegasus Systems 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.
Pegasus Systems
Job
Trello
Board and List
1:manyPegasus Jobs are the project-level container with timelines, task lists, and resource allocation. We extract each Job and create a Trello Board. Within each Board, Lists are created to represent job phases or task categories. Job status (active, on-hold, completed) maps to Board background colour or an archived Board flag. Custom fields on Jobs (e.g., client name, budget code) map to Card-level custom fields only if the destination Trello plan includes them (Premium or Enterprise). Standard tier users receive those values as Card description text.
Pegasus Systems
Task
Trello
Card
1:1Individual task items inside Pegasus Jobs map to Trello Cards. Task name becomes Card title, task description migrates as Card description (rich text preserved), due dates migrate as Card due dates, and assigned Pegasus Users become Card Members via email match. Task status (complete, in-progress, blocked) maps to Card position within Trello Lists. Sub-tasks in Pegasus become Checklist items on the corresponding Trello Card.
Pegasus Systems
User
Trello
Member
1:1Pegasus user accounts with role information map to Trello workspace Members. We extract all active and inactive Pegasus users and match by email address to Trello Member accounts. The customer's Trello admin must ensure workspace membership is provisioned before migration. Inactive Pegasus users are added as Board observers or archived in a reconciled list so historical assignment data is preserved on Cards.
Pegasus Systems
Client
Trello
Label or Card Description (no native equivalent)
lossyPegasus Clients store contact information, campaign history, and performance analytics. Trello has no native client object. We extract client records and recommend storing them as Trello Labels with client name (e.g., Label colour-coded per client), or embedding client contact details in Card descriptions. For agencies that require a full client CRM, we flag this as a separate CRM handoff and recommend a documented client list for import into a dedicated CRM tool post-migration.
Pegasus Systems
Timesheet
Trello
Checklist (no native equivalent)
lossyPegasus per-minute timesheet entries with billable/non-billable flags have no native Trello equivalent. Trello does not offer a time-tracking object. We extract timesheet entries as structured data (date, duration, user, job, billable flag) and write them into Card Checklist items or Card descriptions in a standardised format. For teams that require time tracking post-migration, we recommend a Trello Power-Up such as Prophetic or TrackIt, and the customer documents which Power-Up they have selected so the migration output can be reviewed against it.
Pegasus Systems
Invoice
Trello
No migration (flagged)
1:1Pegasus Invoices are generated from job costs and timesheet data. Trello has no financial objects and cannot store invoice records. We extract invoice data (headers, line items, amounts, payment status) as a structured export file and flag this for the customer's accounting team. Invoices must be migrated to a dedicated accounting platform (e.g., QuickBooks, Xero, FreshBooks) as a separate workstream. We do not load financial records into Trello.
Pegasus Systems
Expense
Trello
No migration (flagged)
1:1Pegasus Expense records capture AP data tied to jobs or clients. Trello has no expense tracking capability. We extract expense data (vendor, amount, date, job association, AP status) as a structured export and flag it for migration to a dedicated accounting tool. The expense export is delivered alongside the migration, not inside Trello.
Pegasus Systems
Media Campaign
Trello
Board (snapshot)
1:1Pegasus Media Campaigns aggregate real-time metrics, client meetings, and new projects. We extract campaign metadata and snapshot the current metrics state as a Card description or Card attachment. Live data connectors from Pegasus do not migrate because Trello has no real-time metric widgets natively. The customer receives a static snapshot of campaign performance at migration time; ongoing media metrics require a separate reporting tool or connector.
Pegasus Systems
Attachment
Trello
Card Attachment
1:1Documents and files attached to Pegasus Jobs, Clients, or Invoices are extracted as binary blobs or URLs. We preserve attachment associations by linking them to the migrated Trello Card via the Card's attachment feature. Large binary files (over 10 MB) are uploaded to the customer's Google Drive or SharePoint and linked as a URL attachment in Trello to avoid Trello's attachment size limits.
Pegasus Systems
Custom Field
Trello
Custom Field (Premium/Enterprise only) or Card Description
lossyPegasus custom fields on Jobs and Clients require explicit mapping decisions. If the destination Trello workspace is on Premium or Enterprise, custom fields migrate as typed Trello Custom Fields (text, number, date, dropdown, checkbox). If on Standard, custom field values are written into Card descriptions as structured text and the customer receives a custom field inventory document listing every Pegasus custom field, its type, and its mapped Card description location for manual rebuild if the workspace upgrades.
Pegasus Systems
Financial Record
Trello
No migration (flagged)
1:1Pegasus holds assets, cash flow statements, and chart-of-accounts data at the finance layer. Trello has no financial object model. We extract the accounts structure and current balances as a structured export and flag the financial records for migration to a dedicated accounting platform. Historical transaction history tied to closed or locked Pegasus periods is noted separately for the customer's accountant to reconcile before export.
Pegasus Systems
Archived Job/Task
Trello
Archived Card
1:1Archived Pegasus Jobs and Tasks map to Trello archived Cards. We extract archived records during data preparation and create archived Cards in the corresponding Trello Board. The customer must confirm whether archived records should be included in the migration scope, as archived data volumes can significantly affect extraction time.

Gotchas + challenges
Platform-specific issues from each side, plus the pair-specific challenges that don't show up on either platform's page on its own.
Pegasus Systems gotchas
No documented public API means bulk exports require workarounds
Reporting module defects cause visibility gaps in migrated data
Financial period locking may cause re-opening conflicts
Change management scope creep can inflate migration timelines
Trello gotchas
Billing model uses maximum seat quantity at term midpoint
Custom Field data historically stored in pluginData
API rate limits are token-gated and can block bulk migration
Guest-to-paid seat conversion triggers on multi-board membership
Automation command runs are capped per plan and overage triggers upgrade pressure
Pair-specific challenges
Migration approach
Discovery and Pegasus export method agreement
We audit the source Pegasus instance across Jobs (active, on-hold, archived), Tasks, Users (active/inactive), Clients, Timesheets, Expenses, Invoices, Media Campaigns, and custom field inventory. We confirm the Pegasus export method: direct file export via Pegasus change management or Excel template extraction. We identify locked financial periods and flag Invoices and Expenses that belong to those periods. We confirm the destination Trello workspace plan (Free, Standard, Premium, Enterprise) because it determines custom field capability and Board limits. The discovery output is a written scope document and a Pegasus export instructions sheet for the customer's Pegasus administrator to execute.
Trello workspace preparation
We review the destination Trello workspace structure. We confirm Board naming conventions (one Board per Pegasus Job), List naming conventions ( Pegasus job phases or task categories), and workspace visibility settings (private vs public). We confirm Member provisioning for all migrating Pegasus users. If the destination is on Standard, we confirm that custom fields will be written to Card descriptions and prepare the custom field inventory document. If Premium or Enterprise, we pre-create custom field definitions in Trello before migration. Workspace admin credentials are required for API-based card creation.
Pegasus data extraction and transformation
We receive Pegasus export files (Excel templates, direct extracts) and transform them into migration-ready datasets. Jobs become Board creation payloads. Tasks become Card creation payloads with parent Board reference resolved. Sub-tasks become Checklist items on parent Cards. Pegasus Users become Member invitations with email-matched Board membership. Client records are extracted into a separate client inventory for Label creation or CRM handoff. Financial records (Invoices, Expenses) are extracted into a structured financial export file and flagged for separate accounting tool migration.
Sandbox migration and reconciliation
We run a full migration into a test Trello workspace (not the production destination) using production data volume. The customer's project lead reconciles record counts (Boards in, Lists in, Cards in, Members in, archived Card count), spot-checks 25-50 Cards against the Pegasus source, and validates that Card descriptions, due dates, and Member assignments match the source. Archived record inclusion is confirmed or corrected at this stage. Any mapping corrections (List naming, Label strategy, custom field format) are documented and applied before production migration begins.
Production migration in dependency order
We run production migration in record-dependency order: Members (provisioned first so Board invitations resolve), Boards (one per Pegasus Job), Lists (job phases per Board), Cards (Tasks with Members assigned), Checklist items (sub-tasks), Labels (client and category), Card descriptions (custom field values and client details), and Attachments (extracted files linked to Cards). Archived Cards migrate last with explicit archive flag set. Each phase emits a row-count reconciliation report. We handle Trello API rate limits with exponential backoff and batch chunking.
Cutover, financial export delivery, and Butler handoff
We freeze Pegasus writes during cutover and run a final delta migration of any Jobs or Tasks modified during the migration window. We deliver the financial export file (Invoices, Expenses, Financial Records) to the customer's finance team with a data dictionary. We deliver the custom field inventory document. We do not migrate Pegasus workflow templates, automations, or reporting configurations to Trello Butler; we document the Pegasus automation inventory so the customer's admin can rebuild priority automations in Butler post-migration. We support a three-day hypercare window for reconciliation issues. Post-migration admin support, training, and Butler rebuild are outside standard scope.
