8 – Migrating with CiviCRM

I have seen several articles and tutorials covering how to do a fresh install of CiviCRM along with Drupal 8. My question is how to properly set up a migration from a combo Drupal 7/CiviCRM site to a Drupal 8/CiviCRM site. I have a fresh D8 install in a local VM and have run the following command to grab the required items for CiviCRM:

composer require civicrm/civicrm-asset-plugin:'~1.0.0' civicrm/civicrm-{core,packages,drupal-8}:'~5.29'

Since I am using CiviCRM Entities in several of my content types via entity reference I would like to ensure that it is properly functioning before proceeding with the actual Drupal migration.

So basically looking for tips on what files need updating in the fresh CiviCRM files in order to get up and running.
