Overview

What this migration involves

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.

Resource Management by Smartsheet

What's pushing teams away

  • Project/role-level resourcing only — independent reviewers note the tool 'is not as strong when you need detailed task-level resourcing or highly complex dependency management', so professional-services-automation buyers often migrate to Kantata or Mavenlink.
  • No native mobile app — field-heavy teams and PMs who travel cite this as a recurring complaint on Software Advice and Research.com.
  • Time-entry adoption is hit-or-miss — utilization data becomes unreliable when staff don't log time consistently, undermining the very forecasts the platform is purchased to produce.
  • Steep learning curve and complex interface for the wide feature set — managing large teams or many concurrent projects becomes inefficient, pushing teams toward simpler resource tools like Float, Runn, or monday Work Management.
  • Cost ceiling — the Resource Management add-on is gated behind higher Smartsheet tiers, with per-user pricing and premium-feature gating making TCO 'a bit steep' (Research.com), particularly for teams that don't otherwise use Smartsheet.

What's pulling them in

  • Free plan supports unlimited users and 10 boards, giving small teams full access to core Kanban functionality before any paid commitment is required.
  • The drag-and-drop board/card/Label interface requires no training, which reduces adoption friction and onboarding time across distributed teams.
  • Atlassian ecosystem integration with Jira, Confluence, and Bitbucket provides native cross-tool workflows for teams already using Atlassian tools.
  • Butler automation on paid tiers enables rule-based triggers without third-party integrations, covering basic workflow automation needs.
  • Simple visual task management with due dates, checklists, and member assignments keeps individual contributors and small teams organized without complexity.

Object mapping

How Resource Management by Smartsheet objects map to Trello

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)

maps to

Trello

Board

1:1
Fully supported

Each 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)

maps to

Trello

Card

1:1
Fully supported

Smartsheet 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

maps to

Trello

List

1:many
Fully supported

Resource 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)

maps to

Trello

Workspace Member

1:1
Fully supported

Resource 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

maps to

Trello

Card Member + Checklist

1:1
Fully supported

Each 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

maps to

Trello

Multiple Boards (Workspace)

1:many
Fully supported

Resource 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

maps to

Trello

Card Comment

1:1
Fully supported

Resource 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

maps to

Trello

Card Label, Due Date, or Description

lossy
Fully supported

Resource 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)

maps to

Trello

Card Comment

1:1
Fully supported

Resource 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)

maps to

Trello

Card Label

lossy
Fully supported

People 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

maps to

Trello

Card Link or Checklist

lossy
Fully supported

Smartsheet 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

maps to

Trello

Not Migrated

1:1
Fully supported

Resource 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

  • Phase hierarchy flattens into lists with no nesting

    Resource Management phases support a nested parent-child hierarchy that organizes tasks into work stages. Trello lists are flat swimlanes within a board with no native sub-list or phase hierarchy. Deep phase nesting (grandchild phases, phase-level dates and budgets) cannot be represented in Trello without losing structural context. We document the full phase tree during discovery and collapse it to top-level lists with child-phase names preserved in card descriptions. Customers with complex phase structures should plan to recreate a phase tracking system in Trello Power-Ups or spreadsheets post-migration.

  • Resource Management automations do not migrate

    Smartsheet automation rules are not exposed via the public REST API, making programmatic migration impossible regardless of destination. Every active automation rule is logged during discovery with its trigger, conditions, and actions. We deliver an automation audit log that maps each rule to a Trello Butler command or a Zapier/Make workflow as a reference for manual rebuild. This is a significant effort for teams with dozens of rules across multiple sheets.

  • Time entries lock after one week in Resource Management

    The Resource Management timer locks time entries after seven days, making them read-only and inaccessible via API. We request a CSV export of all billable hours and assignments during the discovery call before this window closes for any entries in the current week. If the migration timeline extends past one week from discovery, entries from the most recent week may become unrecoverable. We flag this risk explicitly in the scoping document and recommend scheduling discovery and export on the same day for time-entry-heavy accounts.

  • Trello's free tier limits automation and Power-Ups

    Many Resource Management customers use Smartsheet's unlimited automations on Business plans. Trello's free tier includes no Butler automations and only one Power-Up per board. If the customer plans to rebuild Smartsheet-style automations in Trello, they need Premium at minimum ($12.50/user/mo). Standard ($6/user/mo) unlocks unlimited Power-Ups but no Butler. We confirm the destination plan tier during scoping and adjust the automation rebuild recommendations accordingly.

  • Attachments and file links do not migrate from Smartsheet

    Smartsheet's export and API responses explicitly exclude Attachment files. Row-level file attachments and Groupings are omitted from all export paths. We direct customers to use Smartsheet's Backup tool to download attachments separately before migration. We preserve the sheet structure including column order and cell values but note that any file attachments must be re-linked manually on the Trello cards, or stored in a connected Google Drive or Dropbox account with links added to card descriptions.

Migration approach

Six steps for a successful Resource Management by Smartsheet to Trello data migration

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

  6. 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.

Most migrations land between two and four weeks for accounts with fewer than 15 projects and 2,000 task rows without time-entry history. Migrations with larger project counts (20-50 boards), complex phase nesting, or historical time entries requiring pre-lock exports extend to three to six weeks. Trello has a simpler schema than most destination platforms, which generally compresses the migration timeline compared to structured database-style destinations.
