Simplest method:
Update to the latest version and do any required database updates if not done already
Backup your current database, you can do this from Administration -> Backup.
See: https://docs.itflow.org/backups
For ITFlow itself just follow the installation procedure again using the same database details as your current server. This will give you a base ITFlow install
Once installed, You would use PHPMyAdmin on your cloud server to restore the database over the default one you just setup.
