         *   2.2.2 Fetch from older .env file (manually parse)
         *  2.3 Use old ENV vars as default values 
         *  2.4 Ask for all required vars not given as CLI args and if in interactive mode
         *      Otherwise, just use default vars. - DONE
         * 3. Ask user to backup important volumes, env vars, and SQL tables
         *      In th future we can try and automate this for smaller/medium size setups 
         * 4. Drop new docker-compose.yml setup (located inside the container, no network dependencies with appwrite.io)
         * 5. Run docker-compose up -d
         * 6. Run data migration
