# Migrating to new server
|
|
|
|
1. Prepare by lowering DNS TTL for your domains (`matrix.DOMAIN`, etc.), so that DNS record changes (step 4 below) would happen faster, leading to less downtime
|
|
2. Stop all services on the old server and make sure they won't be starting again. Execute this on the old server: `systemctl disable --now matrix*`
|
|
3. Copy directory `/matrix` from the old server to the new server. Make sure to preserve ownership and permissions (use `cp -p` or `rsync -ar`)!
|
|
4. Make sure your DNS records are adjusted to point to the new server's IP address
|
|
5. Remove old server from the `inventory/hosts` file and add new server.
|
|
6. Run `ansible-playbook -i inventory/hosts setup.yml --tags=setup-system-user`. This will create the `matrix` user and group on the new server
|
|
7. 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 manually by running this on the new server: `chown -R matrix:matrix /matrix`.
|
|
8. Run `ansible-playbook -i inventory/hosts setup.yml --tags=setup-all,start` to finish the installation and start all services
