Hi @syntrydy , to convert our application to the redux toolkit standards, we need to start from the store, as per toolkit standards store will be defined as configureStore instead of createStore moreover we need to change all the action methods to the slice which is toolkit standard and need to link all the saga actions to the slice itself.

Overall I can say we need to define almost all the things used in redux again to the toolkit standards.

We can define action methods in slice & keep the saga logic as it is. That way we won't have to create everything from scratch. The only thing will change in this case will be way of writing reducer. Instead of defining into seperate file, we could define it in slice. @duttarnab please review 483774d

Done for scope, session. We will raise issue for rest of code.
