As you know, some customers don’t know very much about server, or technical information. So they will say somes like “Just deploy to live server, it’s okay”.
We strongly request you before deploying to live server
1. Back up all live server’s source code
2. Back up DB
3. DO NOT Turn-off live server before getting confirmation from CUSTOMER (though Appdr)
4. Send to Appdr Steps you gonna do when deployment
5. Check with Appdr about deploy time (In case live server has a lot of real users)
