Application redeploy risk

Doing application re-reeploy is a risky thing, especailly for a web application.

It demands great care and careful test.

1. Always have a backup plan. What if the deployed failed?
   Treat yourself well and leave a fire exit;
   Always renaming table columns instead of droping them while doing application reploy
2. Be careful: i copied my deploy to /tmp/abc directory, then 30 minutes later, when i copy the application, i copy from /tmp, and thre is an old version exists there. I actually deployed an old version.
3. Always do it at office hour when someone else is round
4. keey test server and product server same version, same structure and same config.
