Move to a new data server

The phone carries the warehouse to a new server: when it connects to a new address, its first sync sends the new server everything it has.

Before you switch

On the phone that has everything, while it still syncs with the old server:

1. Settings › Sync with the web: turn Sync photos on and Only on Wi-Fi off, then sync.
2. Wait until no photos are left to transfer: the app gets the full-size photos it has only small copies of. Only full-size photos on the phone can go to the new server.

Switch

1. Start the new server (Run a data server) and add a phone on its Manage page.
2. In the app: Settings › Sync with the web › Scan QR code, and scan the new code.
3. Pull the list down. The phone sends everything; the photos follow in the background. Photos the server already has (the same file, checked by its SHA-256) aren't sent again.
4. Other phones: connect them the same way afterwards. Each sends what it has, and the newer edit of anything wins.
5. Claude Code: claude mcp remove warehouse, then add a token on the new server (see Ask Claude).

Keep the old server's data until everything is on the new one.

A new app

A build of the app with a new name installs beside the old one instead of over it, and starts empty:

1. In the old app (its last update has Export settings): connect it to the server the new app will use and sync until no photos are left to send, as above.
2. Then Settings › Export settings: the file takes the connection along, so export after switching.
3. In the new app: Import settings, which also connects it to the data server, and pull the list down. Everything comes back from the server, photos included.
4. Uninstall the old app once the new one has everything.
