Trouble with manual upgrade 5.6.3.3 to 5.7.5.6
PermalinkI have an unpacked download in the mydomainname/updates/concrete5.7.5.6 folder. However, Dashboard > System and Settings > Update Concrete5 just tells me No updates available.
I looked at the tutorial video athttp://documentation.concrete5.org/tutorials/how-to-manually-upgrad... but I have no idea where he is going at 1:25, going to the file manager. Is that file manager in a Linux Desktop, or Concrete's file manager? Nothing makes any sense to me after this point.
The text instructions athttp://documentation.concrete5.org/tutorials/how-to-manually-upgrad... are completely different than in the documentation link. Maybe these are instructions for upgrading on a linux machine running a Ubuntu desktop or something. I'm using a web hosting account, so I just have terminal access. For example, step 6, I don't see any /index.php/ccm/system/upgrade to visit.

You cannot upgrade a 5.6 site to 5.7. They are different incompatible versions.
The options would be to migrate your site with the migration tool, rebuild, or migrate content manually.

cPanel is probably the most common system for managing hosting accounts, but it's obviously not available on all hosting platforms. Some servers use Plesk, some use their own custom scripts, some only offer FTP or SSH.
What that part of the video is showing is really just generic file/folder operations - it doesn't really matter what you use to put files on your server, it's just a case of uploading a zip and unzipping it. It's not much different than FTP-ing into a server, you'd see the same files.
Where cPanel makes it easier is that it does support the unzipping of files on the server, something that pure FTP can't do. If you're not sure how to do those things, you'd need to contact your host for advice.
(in this case you're not going to be able to update from 5.6 to 5.7, but I thought I'd answer for future reference)
"5.7 is bigger than 5.6, therefore you are running outdated software.
Outdated software is a security risk."
That's simply not the case with 5.6.x, they've given you the wrong information.
