We are currently running pulpcore 3.7 with python 3.7 and an external db. When we use the pulp_installer to migrate the older release to 3.15 with new python 3.8 venv,it run successfully in a test environment. I am wondering how the new version knows the the historical migration file. Should I copy the historical migration files from older python 3.7 venv to the new 3.8 venv first?</div></body></html>
