Hi Hi, do you know of an easy way to import the projects from redmine to jira using this method? we have our issues broken up into several projects in redmine, and want to keep that organization during the import. many thanks!

I believe you have to create the projects individually in JIRA

And then import them separately as well. Be sure to change the project_id in the above query

Does your command import Redmine bug history (comments) into Jira also?

It merge all comments into "description" field.
To import comments CSV must have multiple columns "comments" with pattern:
{datetime};{authorEmail};{text}

Added attachments and comments:
