How to Migrate from Trello to an All-in-One Work OS
Trello is the gentlest introduction to organized work ever built. Teams outgrow it precisely because it succeeded at getting them organized enough to need more.
Trello deserves affection. Its board, list, and card model is so intuitive that entire teams adopt it without training, and for lightweight kanban it remains hard to beat. If you are migrating, it is usually a sign of success: your work has grown beyond what a single board can hold.
The friction is scale and structure. Trello boards do not talk to each other, cards have limited native fields without Power-Ups, and reporting across many boards is difficult. When a team needs dependencies, cross-project reporting, or connection to CRM and contracts, it has outgrown the board metaphor and is ready for a structured work OS. Recognizing that moment early turns the migration into a planned upgrade rather than a scramble once the boards have quietly become unmanageable.
Inventory your boards and Power-Ups
Trello's simplicity means the inventory is quick, but Power-Ups add hidden structure you must account for. List every active board, its lists as workflow stages, and any Power-Ups that store data, such as custom fields, calendars, or voting.
- Active boards with live cards, which migrate to projects and tasks.
- Lists, which usually become workflow statuses.
- Labels, which become tags or priority fields.
- Power-Up data such as custom fields and due dates, which must be exported deliberately.
Export cards without losing the details
Trello can export a board as JSON, and paid plans support CSV. The JSON export is the more complete option because it includes checklists, comments, attachments, labels, and due dates. Use it, and keep a dated archive of every board.
The details most easily lost are checklists, attachments, and comment history. Confirm during a pilot import that checklists became subtasks, attachments carried across or were relinked, and comments preserved their authors and dates. Map Trello members to destination accounts so cards land with real owners. Also preserve card due dates and any start dates, since these drive the calendar and timeline views your team will expect to work as before once the cards arrive.
Rebuild Butler automations and connect boards
Many mature Trello workspaces quietly depend on Butler, the automation engine that moves cards, sets due dates, and posts updates on a schedule. Because Butler rules live outside the card data, a board export will not capture them, so list every rule you rely on and describe its trigger and action in plain language before you migrate. That list becomes your rebuild specification in the destination.
The more consequential Trello limit is that boards do not talk to each other. Teams work around this by copying cards between boards or maintaining a master board by hand, which is manual reconciliation in disguise. When you migrate, treat those copied cards as a single record that should appear in multiple views, not as duplicates to keep in sync. This is where a structured destination pays off immediately, because one card can belong to a project, a client, and a reporting view at once without ever being copied.
Keep the simplicity, gain the structure
The risk in leaving Trello is trading simplicity for complexity you do not need. Avoid it by choosing a destination that still offers a clean board view, then adopting more structure only where your team actually feels the pain, such as dependencies or cross-board reporting.
Atlas keeps the board experience Trello users love while placing it on a shared data model, so a card can become a task that connects to a project, a client, and a contract without leaving the platform. Start with a familiar board, then grow into the structure you need. See /all-in-one for the full picture and /pricing for the free tier to pilot the move.
