Utilities/Tools to migrate from zephyr enterprise to zephyr scale

Hi Community,

I am reaching out to get informed about tools or utilities available for total migration from zephyr enterprise to zephyr scale. I would like to migrate all the testcase , project, release and their history to zephyr scale. I am bit aware about zephyr API documentation but it would be really helpful if someone can provide latest zephyr API documentation.
I am current using https://zephyrenterprisev3.docs.apiary.io as my reference point.

Thank you.
