Switch from Tududi

Tududi keeps everything in one SQLite database file, and OpenTodo can read a copy of it. Your areas, projects, tasks, subtasks, tags, project notes and repeats come with you.

Export from Tududi#

Tududi has no export button; you copy its database file. Whoever runs your Tududi server does this:

1. Stop Tududi (for example docker stop tududi), so the file holds everything and is not changing while you copy it.
2. Copy the database file out of Tududi's data folder. With the Docker image it is production.sqlite3 in the volume mounted at /app/db (docker cp tududi:/app/db/production.sqlite3 . works too). Without Docker it is the file DB_FILE points to, backend/db/production.sqlite3 by default.
3. Start Tududi again. You can compress the file into a ZIP to upload it faster.

Import into OpenTodo#

1. Open Settings → Data → Import data (or press g then Shift+I).
2. Choose production.sqlite3 (or the ZIP). The preview shows Tududi (database).
3. Check the warnings and select Import.

The file is read on your server from a private copy, read-only, and deleted right after the preview or import.

What carries over#

• Areas become parent projects; projects stay inside them. A done or cancelled project arrives archived.
• Project descriptions and the notes of each project become the project's notes.
• Tasks, with subtasks under their parent task. Tasks placed directly in an area land in that area's project; tasks without a project go to your Inbox (or the project you choose as the target).
• Items of Tududi's own inbox that you have not processed yet become tasks in your Inbox.
• Priority: high becomes priority 1, medium 2, low 3, none 4.
• Due dates with their time, start dates, estimates, reminders and task notes. Comments are added under the note with their date.
• Done and archived tasks arrive completed; cancelled tasks too, with a warning. In-progress, waiting and planned tasks stay open.
• Tags become labels. The built-in someday tag parks a task in Someday.
• Tasks on your latest Today plan that have no due date are due on the day you import, with a warning.
• Repeats: daily and every N days, weekly on chosen weekdays, monthly on a day, on the 1st–4th or last weekday and on the last day, repeat after completion, and the end date.
• Each task remembers its Tududi id, so importing the same database again skips what is already there.

The full mapping is in Import formats.

What does not#

• Notes without a project are named in the preview but not imported; copy them into a project's notes.
• Tags on projects (OpenTodo projects have no labels; the tasks keep theirs).
• Repeats every 2 or more weeks on chosen weekdays become "every N weeks" with a warning; other combinations the rule grammar cannot say are dropped with a warning.
• Attachments (their files are not in the database), task relations, habits' streaks, goals and people.
