msgid "This documentation explains how to migrate your Matrix services (server, client, bridges, etc.) and data **from an old server to a new server**."
msgid "This migration guide is applicable if you migrate from one server to another server having the same CPU architecture (e.g. both servers being `amd64`)."
msgid "If you're trying to migrate between different architectures (e.g. `amd64` --> `arm64`), simply copying the complete `/matrix` directory is **not** possible as it would move the raw PostgreSQL data (`/matrix/postgres/data`) between different architectures. In this specific case, you can use the guide below as a reference, but you would also need to avoid syncing `/matrix/postgres/data` to the new host, and also dump the database on your current server and import it properly on the new server. See our [Backing up PostgreSQL](maintenance-postgres.md#backing-up-postgresql) docs for help with PostgreSQL backup/restore."
msgid "If you have any questions about migration or encountered an issue during migration, do not hesitate to ask for help on [our Matrix room](https://matrix.to/#/%23matrix-docker-ansible-deploy:devture.com). You probably might want to prepare a temporary/sub account on another Matrix server in case it becomes impossible to use your server due to migration failure by any chance."
msgid "Prepare by lowering DNS TTL for your domains (`matrix.example.com`, etc.), so that DNS record changes would happen faster, leading to less downtime."
msgid "To do so, it is recommended to run the `systemctl` command on the server. Running the playbook's `stop` tag also stops the services, but just once; they will start again if you reboot the server."
msgid "After you've confirmed that all services were stopped, copy the `/matrix` directory from the old server to the new server. When copying, make sure to preserve ownership and permissions (use `cp -p` or `rsync -ar`)!"
msgid "**Note**: because the `matrix` user and group are created dynamically on each server, the user/group ID may differ between the old and new server. We suggest that you adjust ownership of `/matrix` files. To adjust the ownership, log in to the new server and run the command:"
msgid "After starting the services, you probably might want to ensure that you've migrated things correctly and that services are running. For instructions, see: [check if services work](maintenance-checking-services.md)"
