I’m Roy — I build security-first tools and write down the thinking behind them as I go. This is the notebook: half build log, half field notes, half whatever I’m actually working through that week.

Workflow: Migrate All CherryTree Notes to Joplin Server – Part 2

Part 2: How I moved the rest of my 41,000 notes from CherryTree to a self-hosted Joplin Server in five batches, caught a silent import bug that dropped 88 pictures, froze the originals, and decided which private notes to keep out.

Workflow: Migrate All CherryTree Notes to Joplin Server – Part 1

Part 1: CherryTree has no tablet app, so I moved 46,000 notes to Joplin with my own sync server at home. Here’s how I planned it, converted everything, proved nothing was lost, and got my tablets syncing, plus the pitfalls that cost me the most time.

Why I Moved My Notes Out of CherryTree

For years I wrote every course note, certification study guide and project log in CherryTree, a free note-taking app for desktop computers. By this year it held about 46,000 pages.

So I moved everything to Joplin, a free notes app that works on computers, phones and tablets.
