What we wanted to change in the first place was our app upgrade procedure. Some developers told us that it's not so easy to submit a new version of application and replace previous one, and some others told that they already became familiar with the old system.
So we decided to support both type of developers at the same time, by preserving current procedure and adding up a new way of upgrading apps.
This is what we've done:
"File replace" was upgrade actually
1. Confusing menu name
2. Not so good UI/UX
3. Version isn't associated with Manifest
Stop Replacements! Just update!
1. Just click update button on the list!
2. Totally easy to use, right?
3. Add various kind of file information just for APK
Problem with the old way

As you can see in the video above, there were some developers - especially non-Korean - who submitted more than one application, while thinking they're upgrading their existing one. We have got tons of mails why we designed upgrade procedure so confused.
Why not! we kept both!
I really struggle to solve this problem and to make user familiar with provious system without any problems by finding UX improvement. As a result, I drastically modified UI/UX of website that can keep old & new operations for APK update.
1. New way: Tell us the uploaded binary is an update or not
