as part of the sitecore security bulletin: https://support.sitecore.com/kb?id=kb_article_view&sysparm_article=KB1001300 to update the hotfix it is recommended to upgrade the minor version before adding hotfix.

Currently we are using sitecore 10.1.0 version, How we can update the sitecore minor version from 10.1.0 to 10.1.2?

Minor version update will be same as normal upgrade or it can be done through the package installation ?
