Swapping a root site, but maintaining a list

Hi all,

We are swapping our dated root site for a modern site. Our current root site was created back in 2016, and uses SharePoint classic. We plan to swap for a modern site and launch with a fresh look for our organization's intranet.

I understand when swapping a root site, the initial root site's site collection is archived. Including lists.

We have an expansive IT Intake list on our current root site, which includes workflows that send email approvals, as well as Jira integrations. We still use this IT Intake list.

Is there any way to preserve the IT Intake list and/or migrate it, its workflows, and content onto the new root site without losing any data or duplicating our efforts? I have seen that you can extract the list and import it to a new list, but this is not ideal.

As a note: we cannot use third-party migration tools at this time. 

Thanks!
