When upgrading to the latest satellite version, some issues might arise.
In my particular case I lost all subscriptions and I also lost the tftp functionality.
The subscriptions where easily fixed by running a script on all the hosts re-registering them to the satellite and the tftp functionality had to be re-enabled in the capsule server.
Mind you the katello-installer command has been replaced by the satellite-installer command, which takes –scenario satellite or –scenario capsule as arguments, which in turn are accompanied by their respective sub-arguments

New features for the 6.2 version that did make the cut:
- Container host provisioning, supporting and managing Red Hat’s lightweight container operating system, Red Hat Enterprise Linux Atomic Host. Red Hat Satellite supports enterprises who are migrating to a lightweight container architecture, enabling them to run Red Hat Enterprise Linux Atomic Hosts as a compute resource and directly deploy containers to Red Hat Enterprise Linux Atomic Host. In addition, Red Hat Satellite now supports the Open Container Initiative format and registries.
- Remote execution, enabling users to take multiple actions against a group of systems while automating workflows. With these new capabilities, users can reboot a system after a patch install, or conduct rolling upgrades across hundreds of systems with the same ease and consistency as updating a single system. New scheduling features and dashboards enhance interaction with systems under Red Hat Satellite management, bringing increased efficiency to its provisioning and discovery processes.
- Support for disconnected environments. Red Hat Satellite 6.2 provides the ability to synchronize and export content from one Red Hat Satellite server to another, a new feature designed for workloads that may require systems management solutions to run disconnected from the Internet for security purposes.
- Expanded capsule management. The Red Hat Satellite Capsule Server, which provides federated services especially helpful for scaling, can now provide deeper insight into the health of the capsule, including service run statues from the centralized Red Hat Satellite console. This enables administrators to create various capsules in different geographic locations where datacenters may be located.
- More flexible provisioning via new discovery enhancements in Red Hat Satellite, helping to simplify the process of building systems and enable end users to more efficiently provision systems in secured environments where DHCP (Dynamic Host Configuration Protocol) and PXE (Preboot Execution Environment) may not be available.
- Enhanced migration services via the ability to import existing hosts running on any version of Red Hat Satellite 5 or 6 thanks to new feature scripts and automation capabilities. This bootstrap script automates the process of registering systems to Satellite, reducing the steps needed to add existing systems to Red Hat Satellite.
