HowTo import issues

Since 3.2.0 Redmine can import issues.
In the issues tab there is a import link on the right. You can import any csv-type file. The first line must contain the column names. You can freely assign them to the different fields of an issue.

Notes on different Fields

Parent Issue

If the field starts with an #, the issue with that id is referenced. If the field contains a number it references the index of the issue in the import. Note that it's not the line number as line 1 contains the header.

Assignee

This must be the username. (Might be that the Name works, too, but I didn't check.)
