Plan your scheduler transition
Before starting the scheduler transition, you must learn about what Fair Scheduler configuration can be converted into a Capacity Scheduler configuration prior to the upgrade, what configuration requires manual configuration and fine-tuning.
The features of Capacity Scheduler are not exactly the same as the features of Fair Scheduler. Hence, the fs2cs conversion utility cannot convert every Fair Scheduler configuration into a Capacity Scheduler configuration. You must learn about what properties are auto-converted and what requires manual configuration. In addition, there are Fair Scheduler features that do not have an equivalent feature in Capacity Scheduler.
