monitoring/dashboards/index.tsx  (checkbox select, hasInlineFilter which is not supported in V6 Select, convert to Typeahead)

timespan-dropdown.ts (Currently using DropdownDeprecated, should be using a Select) 

poll-interval-dropdown.tsx (Currently using DropdownDeprecated, should be using a Select) 

`FilterSelect`, `VariableDropdown`, `TimespanDropdown`, and `IntervalDropdown`are the components that need to be updated; frontend/packages/dev-console/src/components/monitoring/MonitoringPage.tsx is the only valid instance usage of `MonitoringDashboardsPage` as web/src/components/alerting.tsx is orphaned.

Note

SelectDeprecated are replaced with latest Select component

AC: Go though the mentioned files and swap the usage of Deprecated components with PF components, based on their semantics (either Dropdown or Select components).
