Redmine

We are now increasingly using Atlassian tools (Jira and Confluence) in our company. For this reason, the tickets from Redmine should also be moved to Jira.
Since many tickets also have attachments, we started the migration via a local Jira installation. This way, the attachments are also taken along, but the transaction history of the tickets is not transferred.
This does not seem to be offered by Redmine for transfer.
Is there a way to transfer this history as well? The history is very important for some colleagues in our company.
