func (*State) ShouldEnableCSIMigration added in v1.3.0 

func (s *State) ShouldEnableCSIMigration() bool

ShouldEnableCSIMigration returns if CSI migration feature gates should be enabled. This function ensures we'll keep CSI migration feature gates enabled for existing clusters if they're already enabled or if we're starting the CCM/CSI migration process

func (s *State) ShouldEnableInTreeCloudProvider() bool

ShouldEnableInTreeCloudProvider returns if in-tree cloud provider should be enabled. This function ensures we'll keep in-tree cloud provider enabled for existing clusters if it's already enabled, or disable it if we're completing the CCM/CSI migration process

func (*State) ShouldUnregisterInTreeCloudProvider added in v1.3.0 

func (s *State) ShouldUnregisterInTreeCloudProvider() bool
