Upgrading from `v0.13.x` to `v0.14.x`

Binary installation

Stop Stalwart in every single node of your cluster. If you are using the systemd service, you can do this with the following command:
```
$ sudo systemctl stop stalwart
```
Backup your data following your database system's instructions. For example, if you are using RocksDB or SQLite, you can simply copy the data directory to a backup location. If you are using PostgreSQL or MySQL, you can use the pg_dump or mysqldump commands to create a backup of your database. If your database does not support backups, you can use the built-in migration utility to export your data to a file. For example:
```
$ sudo /opt/stalwart/bin/stalwart --config /opt/stalwart/etc/config.toml --export /opt/stalwart/export
$ sudo chown -R stalwart:stalwart /opt/stalwart/export
```
Download the latest binary for your platform from the releases page and replace the binary in /opt/stalwart/bin.
Start the service. In a cluster, you can speed up the migration process by starting all nodes at once.
```
$ sudo systemctl start stalwart
```
