Today, I will share my experience around the question: Why suddenly minor upgrade doesn't overwrite old files? It always rocks but not this time! I used to struggle for an answer at least twice in just a couple of months. To resolve this question completely, the last time, I determined to find out the root cause (yes, I paid a good half day on it!). Some of you may wonder, why I had to wait until the last time to solve the issue, but the first time? Actually, it's understandable: TIME issue. Sometimes, we rush for release and we just need to make things move first. With this kind of issue, the most difficult part is tracing out the root cause, fixing it is not really a big deal. Enforcing major upgrade is always a perfect workaround to overcome this issue.
