Chapter 3. Transitioning from Satellite 5 to 6

This chapter describes the prerequisites for performing a successful transition from Red Hat Satellite 5 to Satellite 6, and the basic transition work flow. It also describes how to install and use the required transition tools, and covers the most common transition use cases.
The complete transition workflow consists of several phases:
  • Satisfy requirements: this phase consists of ensuring that all transition prerequisites are satisfied. Failure to meet these requirements might result in an incomplete or failed transition.
  • Preparation: this phase consists primarily of preparing the Satellite 6 system to receive data from the existing Satellite 5 system.
  • Transition: this phase consists of exporting the data from the existing Satellite 5 system, transferring that data to the Satellite 6 system, and then tuning the configuration to suit your deployment.

3.1. The Transitioning Strategy

Several strategies are envisioned for transitioning from Red Hat Satellite 5 to Satellite 6. The two primary strategies are passive transition and active transition, both of which involve developing a Satellite 6 architecture alongside your Satellite 5 architecture.
This guide focuses on the active transition strategy, and how to use the tools provided in Satellite 5 and Satellite 6 to achieve a successful transition.
Passive Transition

In a passive transition scenario, the workloads remain on Satellite 5. This strategy is most appropriate if your Satellite deployment is complex and involves significant integration with other applications via APIs or other processes. In this case, Red Hat Satellite 6 is deployed to manage only new workloads and projects, whereas Red Hat Satellite 5 is maintained in order to manage existing workloads until they are retired. Satellite 5 data models may or may not be transitioned to Satellite 6. A passive transition gives administrators the most freedom to reconsider their infrastructure with the least possibility of any disruption to services.

Active Transition

In an active transition scenario, all workloads are moved to Satellite 6. The object of this strategy is to decommission Satellite 5 after translating the Satellite 5 data models to Satellite 6 and registering systems to the new Satellite. All new workloads and projects are targeted for management by Satellite 6. An active transition allows data models to remain somewhat similar and familiar with all workloads appropriately migrated to the new Red Hat Satellite. The originating Satellite 5 is then free to be transitioned into an archived state and shut down.
