Overview
Leaving Gauss Box Projects for Trello is a structural migration from a phase-driven, Gantt-native PM suite to a board-based, Kanban-centric tool. Gauss Box organizes work into Projects with Phases, Tasks, and Subtasks; Trello organizes into Boards containing Lists that hold Cards, where Subtasks become checklists within Cards. There is no direct equivalent in Trello for Gauss Box's native Gantt charts, budget tracking, or built-in time and activity logging, so we flag these during discovery and map what is possible through Trello Custom Fields or power-ups at the customer's direction. The critical architectural difference is that Gauss Box does not publish a self-service export API; we coordinate directly with the Gauss Box team to obtain data, which adds a timeline dependency that Trello-side migrations into tools with open APIs do not carry. We do not migrate automations, Butler rules, or power-up configurations as code; we deliver a written inventory for the customer's admin to rebuild.

Object mapping
Each row shows how a Gauss Box Projects 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.
Gauss Box Projects
Project
Trello
Board
1:1Gauss Box Projects map directly to Trello Boards. Project name, description, start date, and end date migrate to Board name, description, and a date Custom Field capturing the project window. Each Board is created at the Workspace level with default visibility set per the customer's preference. We inventory all projects during discovery and flag any with complex nested subprojects that may require multiple boards or a board-per-subproject structure.
Gauss Box Projects
Phase
Trello
List
1:manyGauss Box Phases become Trello Lists within each Board. Phase name and phase-level deadline migrate to List name and a due date Custom Field on the first card or a dedicated date card in the list. Phases are the primary ordering mechanism in Gauss Box; we preserve their sequential relationship by creating Lists in phase order. If a project has more than 25 phases, we split the board into multiple boards per phase cluster to stay within Trello's practical column limit.
Gauss Box Projects
Task
Trello
Card
1:1Gauss Box Tasks map to Trello Cards within the List corresponding to their parent Phase. Task name, description, assignee, due date, priority, and status migrate to Card name, description, member assignment, due date, label (for priority), and List position. Task attachments and comments migrate as card attachments and card comments respectively. We preserve card ordering within each List to match the original task sequence.
Gauss Box Projects
Subtask
Trello
Checklist item
1:manyGauss Box Subtasks become Trello Checklist items on the parent Card. We preserve the parent-child relationship by creating a named Checklist (e.g., 'Subtasks') on each Card containing all child subtasks as checklist items. Subtask status (complete/incomplete) maps to checklist item checked/unchecked. If subtasks have their own assignees, due dates, or descriptions beyond a name, we promote them to separate Cards and add a label 'Subtask-of: [parent task name]' to preserve the hierarchy.
Gauss Box Projects
Gantt Chart Data
Trello
Custom Field (Date)
lossyGauss Box Gantt chart data (task start/end dates, dependencies, milestones) has no native Trello equivalent. We migrate start and end dates as Custom Date Fields on Cards and flag Trello power-ups (Timeline, BigGantt) as the rebuild option for visual Gantt representation. Task dependencies are inventoried as a written dependency map because Trello does not enforce dependency ordering natively; customers use the Dependencies power-up or a third-party tool to rebuild dependency logic.
Gauss Box Projects
Time Entries
Trello
Custom Field (Number)
lossyGauss Box time entries and activity logs have no native Trello equivalent. We migrate time estimate, actual time logged, and budget comparison as Custom Number Fields on Cards labeled 'Estimated Hours', 'Logged Hours', and 'Budget Hours'. Trello does not aggregate these fields automatically; the customer should use a time-tracking power-up (Clockify, Everhour) if ongoing time logging is required, or use the migrated values as a baseline for future tracking.
Gauss Box Projects
Comments
Trello
Card Comments
1:1Gauss Box task and project comments migrate to Trello Card comments. Comment body, timestamp, and author name (resolved to Trello member if the author has a matching Trello account) migrate directly. Threaded comment chains in Gauss Box flatten into sequential comments in Trello with a quoted attribution header (e.g., '[Author] replied:') to preserve context. We note that Trello comments are not threaded and do not support @mention notifications without a power-up.
Gauss Box Projects
Attachments
Trello
Card Attachments
1:1Files attached to Gauss Box tasks and projects migrate as Card attachments in Trello. We map file name, file size, upload date, and the attached-by user. Storage tier constraints on Gauss Box are inventoried during scoping; we flag any attachment sets exceeding 50MB total per Card (Trello's practical limit for attachments) and advise splitting large files across multiple Cards or using Trello power-ups for cloud storage linking (Google Drive, Dropbox) instead of direct upload.
Gauss Box Projects
Custom Fields
Trello
Custom Fields
lossyGauss Box Custom Fields via attribute sets map to Trello Custom Fields on Cards. We inventory the full attribute set schema during discovery, match field types (text, number, date, dropdown) to Trello's supported Custom Field types (text, number, date, single-select, multi-select, checkbox), and create the destination Custom Field definitions before migration. Only Standard ($5/user) and Premium ($10/user) Trello plans include Custom Fields; we confirm the customer's target plan during scoping.
Gauss Box Projects
Users
Trello
Workspace Members
1:1Gauss Box Users map to Trello Workspace Members. We match users by email address and invite any unmatched users to the Workspace before migration. Gauss Box department and role assignments are inventoried as metadata; Trello uses Workspace roles (Standard, Admin, Observer) and board-level membership rather than a department hierarchy, so we map Gauss Box roles to a combination of Workspace role and board member access levels. External collaborators in Gauss Box map to Trello Board guests.
Gauss Box Projects
External Collaborators
Trello
Board Guests
1:1Gauss Box external collaborators with view-only or limited roles migrate to Trello Board Guests. Guest access is granted per board, and we map the original Gauss Box access level (full, limited, view-only) to Trello's Guest permission model (can view, can comment, can edit per board settings). We flag any Gauss Box collaborators that had project-level access but no task-level access, as Trello does not support column-level or card-level access restrictions without a power-up.
Gauss Box Projects
Dashboard Widgets
Trello
Workspace Views (Standard)
lossyGauss Box Dashboard widgets (project health, team activity, resource usage, time overview, budget overview) have no direct Trello equivalent in the Standard workspace views. We deliver a written inventory of each widget with its source data fields and recommend Trello power-ups (Cor本, Screenful, Blue Cat Reports) or a connected BI tool (Looker Studio, Power BI) for dashboard reconstruction. Custom dashboard configurations do not migrate as dashboard layouts; they are documented for manual rebuild.

Pair-specific challenges
Migration approach
Discovery and Gauss Box vendor coordination
We audit the source Gauss Box environment across all projects, phases, tasks, subtasks, custom attribute sets, user roles, departments, external collaborators, and attachment volumes. Because Gauss Box has no self-service export API, we simultaneously contact the Gauss Box team to request a structured data export in a machine-readable format (CSV, JSON, or database dump). We confirm the export format, structure, and delivery timeline before designing the mapping. This step determines the overall migration duration because Gauss Box vendor responsiveness is outside our control.
Schema design and Trello plan confirmation
We design the destination Trello structure: Workspace configuration, Board naming conventions, List creation per phase, and Custom Field definitions for any Gauss Box attribute set fields. We confirm whether Standard ($5/user) or Premium ($10/user) is required based on Custom Field usage, power-up needs, and admin control requirements. If any project has more than 25 phases, we design a multi-board split. Schema is validated in a test Trello Workspace before production migration begins.
User and collaborator provisioning
We extract every distinct Gauss Box user and external collaborator by email address and provision Trello Workspace members and Board guests before record migration. Gauss Box department and role assignments are inventoried as metadata for mapping to Workspace roles and board access levels. Any Gauss Box collaborator without a valid email or who should not continue access is flagged for the customer's admin to resolve before migration.
Production migration in dependency order
We run production migration in record-dependency order: Workspace and Boards first (structure), then Lists (from Phases), then Cards (from Tasks), then Checklist items (from Subtasks), then Custom Field values, then Comments, then Attachments. Card ordering within Lists preserves the original task sequence. Each phase emits a row-count reconciliation report before the next phase begins. Subtasks with rich attributes are promoted to Cards during this step and flagged in the reconciliation report.
Attachment migration and storage validation
We migrate file attachments as Card attachments in Trello. If any Card's attachment set exceeds 50MB, we split the files across the Card and a linked Card (e.g., 'Attachments — Part 2') or recommend a Trello power-up for cloud storage linking (Google Drive, Dropbox) instead of direct upload. Storage tier constraints on Gauss Box are confirmed resolved (all data extracted) before we close the source environment.
Cutover, validation, and automation rebuild handoff
We freeze Gauss Box write access during cutover, run a final delta migration of any records modified during the migration window, then enable Trello as the system of record. We deliver a written inventory document covering: Gantt reconstruction (power-up recommendation), budget and time data (with the migrated Custom Field values and a reference spreadsheet), dashboard widget equivalents (power-up or BI tool recommendation), and Butler rule structure based on the original Gauss Box workflow logic. We support a one-week hypercare window for reconciliation issues. We do not configure Butler rules or install power-ups as part of the migration scope.
