Exactly the best way to upgrade to 5.7 from 5.6.3.1 ?
Permalinkthan, after I TEMPORARY REMOVE that line that throws the excpetion, concrete looks for app.php in the wrong directory.
I stopped that procedure, seems wrong.
I need the exactly correct procedure, maybe I miss something.
I followed these instructions:
1)https://github.com/concrete5/concrete5-5.7.0/
and
2)http://www.concrete5.org/community/forums/installation/how-to-manua...
I have also upload to my local server a full vendor folder.
Thank you to all.

I feel that this would be a pro-dev only migration path. Lots of missing things wouldn't be noticed at first and later, it would be too late and users would have to re-create all their permissions settings.
I strongly believe we should put quite some effort into this, at least if we don't want to get rid of lots of existing concrete5 users.
At this time, can we have a way to migrate content from previous versions to 5.7?
Thanks
