Make sure that you have your secret words and channel backups. Nothing should be lost during migration. This is just in case.
Please note that Citadel requires Debian 11 or Ubuntu 21.10 (or later). When you're ready you can start by opening a terminal and entering the following commands.
First, install some additional dependencies:
sudo apt -y install python3-jsonschema python3-dacite python3-semver
Then, change into the Umbrel directory:
cd umbrel
And switch to Citadel's migration build:
sudo ./scripts/update/update --repo runcitadel/umbrel#master
After that, stop all running Docker containers:
sudo ./scripts/stop
Finally, complete the migration using:
sudo ./scripts/update/update --repo runcitadel/core#stable
That's it! Welcome to your new free and open-source node.
