 The second step is to activate your license on the system. You should run the `tuxctl` tool as root with your Essential Support license key provided as a command line argument like so:
 
 ```text
 # tuxctl --license-key ESA-XXXXXXXXXXXXXXXXXXXXXXXX
 ```
 
+Essential Support customers can upgrade to a new minor version, for example from 9.2 to 9.4 by editing the /etc/dnf/vars/tuxcare_releasever file to specify the new version, like so:
+
+```text
+# echo 9.4 > /etc/dnf/vars/tuxcare_releasever
+# dnf upgrade
+```
+
 :::warning
 Note that if you upgrade past 9.2 you won't be able to upgrade to ESU without a reinstall. ESU customers can find instructions [above](/enterprise-support-for-almalinux/#installing-tuxctl)
