Overview
Moving from Resource Management by Smartsheet to Trello is a simplification and recontextualization migration, not a like-for-like transfer. Resource Management stores projects as structured portfolio entries with phases, allocation percentages, and time entries against a dedicated resource data model; Trello uses a card-and-board schema with no native phase hierarchy, allocation object, or time-tracking model. We extract projects and their nested phases from the Resource Management API, map each Smartsheet Sheet to a Trello Board, each Row to a Card, each Phase to a List, and each Resource Assignment to a Card member assignment with allocation hours embedded as a checklist note. Time entries migrate as card comments to preserve billable-hour history before the one-week lock window closes. Portfolio rollup views, automation rules, and cross-project capacity dashboards do not migrate; we deliver a written audit of these as a rebuild guide for Trello Workspace admins or Butler.

Object mapping
Each row shows how a Resource Management by Smartsheet 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.
Resource Management by Smartsheet
Project (Sheet)
Trello
Board
1:1Each Smartsheet Sheet used as a project container maps to a Trello Board. We extract the Sheet name as the Board name and the primary contact or project owner as the Board administrator. Board visibility (private, workspace, organization, public) is set based on the Sheet's sharing settings during discovery. Lists are pre-created from the Phase structure before card migration begins.
Resource Management by Smartsheet
Row (Task)
Trello
Card
1:1Smartsheet rows map directly to Trello cards within the corresponding Board. Row name becomes Card title, row description (if any) becomes Card description, and row-level dates map to Card due date and start date fields. Status column values map to Trello labels or list position depending on whether the source uses list-based or label-based status tracking. Subtasks map to Card checklists.
Resource Management by Smartsheet
Phase
Trello
List
1:manyResource Management phases are hierarchical parent-child groupings. We flatten the phase hierarchy into top-level Trello lists at the board level. Child phases are noted in the Card description as a metadata field since Trello has no native phase nesting. Phase start and end dates are preserved as Card due dates for the first card in each phase or as board-level milestones in the description. This is a lossy transformation for deeply nested phase structures.
Resource Management by Smartsheet
People (Resource)
Trello
Workspace Member
1:1Resource Management People records (name, email, role, allocation) map to Trello Workspace Members. We invite each person to the Trello Workspace by email during migration setup. Member name and role are preserved in the member profile. Capacity and allocation percentage do not transfer to Trello native fields; they are embedded as checklist items on assigned cards (see Assignments).
Resource Management by Smartsheet
Assignment
Trello
Card Member + Checklist
1:1Each Resource Management Assignment links a Person to a project task with allocation hours and a role. We assign the corresponding Trello Workspace Member to the Card (the person field) and add a checklist item with the role name and allocation hours (e.g., 'Designer — 50% allocation, 20 hrs/week'). This preserves the allocation data in a readable format on the card without requiring a Power-Up. Assignments without a matching Workspace Member are logged for admin resolution before migration.
Resource Management by Smartsheet
Portfolio
Trello
Multiple Boards (Workspace)
1:manyResource Management portfolios aggregate multiple projects under a single capacity and timeline view. Trello has no native portfolio object. We map each portfolio to a Trello Workspace, with each constituent project becoming a Board within that Workspace. Portfolio-level capacity, availability, and forecast data cannot be represented in Trello without a third-party Power-Up or manual rebuild; we note these gaps in the migration handoff document.
Resource Management by Smartsheet
Time Entry
Trello
Card Comment
1:1Resource Management time entries contain date, hours, billable flag, phase, and category. We export all available time entries via CSV from the Reports interface during discovery before the one-week lock window closes. Each time entry is posted as a dated card comment in the format 'Time Entry: X hrs, Billable, Phase: [name]'. Locked entries are noted in the migration report with a flag indicating they could not be exported programmatically. Native time tracking and timesheet views do not migrate.
Resource Management by Smartsheet
Custom Field
Trello
Card Label, Due Date, or Description
lossyResource Management custom fields for projects (priority, business unit, project ID, location) map to Trello Card Labels with color coding. Text and dropdown custom fields are appended to the Card description as structured key-value lines. Trello does not support custom fields as typed, filterable columns outside of Enterprise plan; we map based on what the customer uses most frequently and document the remainder for manual entry or Power-Up configuration.
Resource Management by Smartsheet
Discussion (Comment)
Trello
Card Comment
1:1Resource Management discussion threads on projects or tasks export as Trello card comments. We preserve the comment author, timestamp, and full text. @mentions in Smartsheet discussions are noted as plain text in the migrated comment since Trello mentions operate within its own Workspace. Rich media in comments (file attachments) is excluded from migration per Smartsheet export limitations.
Resource Management by Smartsheet
Project Custom Field (People)
Trello
Card Label
lossyPeople custom fields in Resource Management (skills, certifications, manager, organization structure) are scoped to the People object and visible in the schedule and portfolio views. These do not map to any Trello card-level field natively. We preserve them as Card Labels if the customer uses skill-based assignments, or note them in the migration handoff for Trello Workspace profile configuration post-migration.
Resource Management by Smartsheet
Dependency
Trello
Card Link or Checklist
lossySmartsheet row-level predecessor/successor dependencies do not have a direct Trello equivalent. We evaluate two approaches during scoping: using the Card Linking Power-Up (Premium tier) to create explicit blocking links between cards, or embedding dependency metadata in Card checklists (e.g., 'Blocked by: [Card Name]'). The approach depends on the customer's plan tier and dependency complexity.
Resource Management by Smartsheet
Report
Trello
Not Migrated
1:1Resource Management reports aggregate filtered views of project and people data. Trello has no native reporting equivalent beyond board-level statistics. We export report definitions as a separate reference document so the customer's admin can identify which Smartsheet report filters to replicate manually in Trello or via a Power-Up. Report data itself is already captured in the migrated project and assignment records.

Pair-specific challenges
Migration approach
Discovery and data export
We audit the Resource Management account across all projects, people, assignments, phases, time entries, custom fields, and any automation rules. We verify the Smartsheet plan tier (Business or Enterprise required for API access; Pro requires CSV report exports). We extract project and assignment data via the Resource Management REST API (projects, users, assignables, assignments, time entries endpoints) and request a time-entry CSV export via the Reports interface before the one-week lock window closes. The discovery output is a written migration scope with record counts, phase tree structure, and any data flagged as inaccessible.
Schema design and Trello workspace setup
We design the Trello destination schema: one Workspace per Resource Management account (or one per portfolio if the source has multiple portfolios), one Board per project, Lists corresponding to top-level phases, and Card Labels derived from Resource Management custom field values. We pre-create all Workspace members by inviting the extracted people list. Label sets are configured to mirror the most-used custom fields (priority, business unit, project type). If the customer uses Trello Premium, we plan Card Linking for dependency representation; if Standard or Free, we use checklist-based dependency notes.
Board and list creation
We create all Trello Boards in the destination Workspace before any card migration begins. Each Board is named from the Smartsheet Sheet title, with the project description and key dates in the Board description. We create Lists within each Board corresponding to the top-level phase names from Resource Management. For projects with no phase structure, we create default Lists (To Do, In Progress, Done) or migrate the Smartsheet row-level status column as List names depending on the source data structure.
Card and checklist migration
We migrate Smartsheet rows as Trello cards in the correct List (phase) within each Board. Card title, description, start date, and due date map from the corresponding row columns. Subtasks from Smartsheet become Card checklists. Assignment allocation hours and roles are added as checklist items on each card, with the assigned Workspace Member set as the card member. Row-level comments migrate as card comments with author and timestamp preserved.
Time-entry comment threading
We post all exported time entries as dated card comments against the correct card in the destination. Each comment is formatted with hours, billable flag, phase category, and date. Entries that were locked before export are flagged in the migration report with a note that they could not be retrieved. We do not use any Trello time-tracking Power-Up for migration; the data is preserved as comment metadata that the customer can read and optionally sync to a time-tracking Power-Up post-migration.
Validation, cutover, and handoff
We run a reconciliation pass comparing migrated card counts and checklist counts against the extracted Smartsheet row and assignment counts. A 25-record spot-check compares card titles, member assignments, and due dates against the source data. We deliver the migration handoff document covering the automation audit log, the portfolio gap summary (items that cannot be natively represented in Trello), the phase-tree structure for manual phase rebuilding, and the time-entry locked-entry flag list. We provide a one-week post-migration support window for data discrepancies; workflow rebuilds and Power-Up configuration are outside migration scope.
