How to transfer all tasks from Jira to Redmine?

Question

Hello!
The question is - by what means can I transfer all tasks from Jira to Redmine? As far as I remember, you can write a jql query, generate xls with all the fields, but how to throw them into redmine?
used the Zapier service, but it can only pull new tasks. and now, I need to drag the old ones while saving all the fields (author, task status, etc.)
