@estradat,
Anything you want to edit the code of should be cloned from the parent to the child.
Don’t change any paths. The only reason you would have to change paths is if they were absolute paths i.e. said “MigrationBase/templates” etc.
But those are relative paths. They point to a folder in your child theme if it’s there and if not they pass through to the parent.
