i have a mediawiki site version 1.15 running that i installed myself. I would like to upgrade mediawiki to 1.16 and think installatron would be an option to use. However, i did change quite some things to my install. Not only extensions but also some editing in core mediawiki files.
1. what happens when i import my own installation to installatron? Will i lose the changes that i have made, are there risks?
2. what happens when i then upgrade mediawiki with installatron? Again, Will i lose the changes that i have made, are there risks?
