Debian places redmine files in non-standard locations to make it easier to build a redmine server that can handle multiple instances. However, this makes it hard to find things. Following are some locations we may need to find.
/usr/share/redmine/lib/plugins
/var/lib/redmine/default/files
I find this a pain for backups. I tend to back up directory trees, so you could back up /var/lib/redmine/*, but instead, I simply make that directory a symlink to someplace I already back up, like /home.
mkdir /home/redmine_data mv /var/lib/redmine/default/files /home/redmine_data ln -s /home/redmine_data/files /var/lib/redmine/default/files
I moved from OpenProject to Redmine. OpenProject spends more time on GUI than I wanted, and since it was based on Redmine, I just decided to install that. However, OpenProject says it exports, but never got that working. Redmine imports tasks only, but not projects, users, etc… (there is a plugin that may do it, but I did not try).
Brief instructions on importing issues from a CSV. I did not try this.
https://redmine.org/projects/redmine/wiki/HowTo_import_issues
Project - must exist Parent Issue - A number, IN THE SPREADSHEET (row - 1), or a pound sign followed by a number, which is existing issue # something
So, if it has a 5, it will be the fifth issue in the import spreadsheet (row 6, since the header is on row 1) If it has a #5, look for the existing issue in Redmine with that issue number
Assignee - the login name or the first/last name of who the issue is assigned to
Category - A category for it. May be in the list of existing categories, or my create a new one.
Start Date = date, in YYYY-MM-DD format the issue was created End Date = date, in YYYY-MM-DD format the issue was closed Author - the login name of the person creating the project (defaults to user doing the import, probably)
Subject - the subject line of the issue
