Trello Downgrade: Ten Boards Stay Open, the Rest Close

Trello is unusually careful with its language here, and the care is doing real work. The documentation does not say boards are removed. It says they are closed, but not deleted.

That distinction is the whole page, and it is the difference between losing your work and temporarily losing sight of it.

Ten boards, chosen by activity

On downgrading, the Workspace's 10 most active boards stay open. Everything else closes.

The part to pay attention to is the selection criterion. Activity decides — not importance, not recency of creation, and not your opinion.

Consider what that does to a real Workspace. The board your team updates hourly is safe. So is the one where someone keeps dragging cards around. Meanwhile:

• The client archive you refer to twice a year.
• The onboarding checklist that only moves when somebody joins.
• The board holding last year's finished project, kept for reference.
• The personal board where you park ideas.

Quiet boards are frequently the valuable ones, because quiet means finished, and finished means it is a record rather than a workspace.

So do the choosing yourself. Trello's own guidance is that before downgrading you can close extra boards or move them to another Workspace. Spending twenty minutes deciding which ten matter is strictly better than letting an activity metric decide for you.

View-only is a people problem, not a board problem

The second limit catches teams rather than individuals, and it presents confusingly.

Boards in the Workspace become view-only until the collaborator count drops below 10.

The confusing part is that this looks like a board restriction. Everyone can see everything and nobody can change anything, which reads like a permissions fault or a billing failure.

It is neither. It is a headcount. The fix is removing collaborators — and in most Workspaces that have been running a while, several of them left the company months ago and nobody cleaned up.

Audit the member list first. It is often enough on its own.

Hidden, not deleted — again

On Power-Ups, automation and the rest: "Data from paid features will be hidden, but not deleted."

This is the same posture as the boards, and the same posture Asana takes. Across the category there is a clear convention emerging: paid tiers gate access, not existence. Vendors want a downgrade to be reversible, because a reversible downgrade is a customer who might come back.

Good for you, with one caveat. Hidden data is not exportable data. If you want a copy that lives outside Trello, you need it while the features still work — which means before the end of the billing period, not after.

Use the billing period

"Workspaces keep all current paid features until the end of their billing period."

You have already paid for that time. Everything works. It is the correct window for all the preparation, and most people spend it waiting for the change to happen to them.

A sensible order:

1. Audit collaborators and remove anyone who has left.
2. Decide which ten boards you want open, and close or move the rest yourself.
3. Export anything you want outside Trello while Power-Ups still work.
4. Let the downgrade land.

Export carries less than you think

One warning if the plan is to leave rather than to downgrade.

Trello's JSON export is bounded in a way that surprises people: it carries only the 1,000 most recent actions on a board, and CSV export requires Premium. So a long-running board exported after a downgrade gives you the current state and a truncated slice of its history.

That is scored in full in our Trello exit report, which puts it at 20 out of 30 — and the deduction is almost entirely that 1,000-action ceiling.

How it compares

Trello's downgrade is among the more forgiving in the category: nothing is destroyed, the rules are published plainly, and the restrictions lift the moment you are back under them.

Its one genuine weakness is that the ten survivors are chosen by a metric rather than by you — a small thing that becomes a large one if your most valuable board is also your quietest.
