To use Mirantis Secure Registry (MSR) 3.0.x, you must perform a fresh installation, as it is not currently possible to upgrade to MSR 3.0.x from any MSR 2.x.x version. You can, though, upgrade from MSR 3.0.x to a later 3.0.x patch version.
Before upgrading from MSR 3.0.0 to a later patch version, you must confirm that the cert-manager component is version 1.7.2 or later:
helm history cert-manager
To upgrade cert-manager to version 1.7.2:
helm upgrade cert-manager jetstack/cert-manager \ --version 1.7.2 \ --set installCRDs=true
Schedule your upgrade outside of peak hours to avoid any business impact, as brief interruptions may occur.
To upgrade to a new patch version:
helm upgrade msr msrofficial/msr --version 1.0.<patch-version> --set-file license=path/to/file/license.lic
