Migrate field validations from D7

Problem/Motivation

I have not found a D7 migration in the module code and all my D7 validators do not exists after the site migration. I have so many and do not like to redo all of them again and again with every drupal version upgrade.

Is there any ongoing process to allow people to upgrade their D7 sites without loosing everything?
