I want to accomplish an easy update procedure for web software that is used by multiple users.
The idea is to have the software with multiple versions at
public-html/ folders of the users there are symlinks to the latest version of the software, that can easily be changed if there is a new version of the software.
This does not work though, if there are user-specific config files or subfolders like for example data/, that may not be updated and need to be taken to the next version.
What are best practice ideas on how I can accomplish this for future easy updates?
