Hi @razriel !
Thank you for contacting NXP Support!
NXP doesn't have documentation about that, but for the control version, you can use git.
If you intend to do long-term support for your product, I recommend using a Docker Yocto builder container, with Docker Yocto builder you can build your images with the same Yocto Project over several years.
I think is possible to use Docker Yocto builder and git to have better revision control, but I am not sure.
Please read the git and Docker documentation.
