Why this import flow matters now
Many teams arrive with real Trello structure, and the biggest blocker is rebuilding everything from scratch.
This flow removes that friction: lists, cards, labels, due dates, and checklist data are moved in one validated step.
The goal of this release is practical: clear, safe, and predictable migration so teams can execute immediately.
Limits and validations in this version
- Up to 200 active lists.
- Up to 5000 open cards.
- Up to 1000 unique labels.
- Up to 200 checklist items per card.
- Up to 50,000 checklist items total.
- Invalid text is sanitized to remove invisible spoofing or malformed characters.
