Transfer Coroutine Dispatcher's Tasks to another Dispatcher

My question is simple, given Dispatcher 1, how would you transfer Dispatcher 1's tasks to another Dispatcher named Dispatcher 2?

Not sure what transfer would mean but yes you can jump between threads. You can use withContext within a coroutine to switch between threads. Like so:

val customContext = newSingleThreadContext("CustomContext")

runBlocking(Dispatchers.Default) {
    // Started in DefaultDispatcher
    withContext(customContext) {
        // Working in CustomContext
    }
    // Back to DefaultDispatcher
}

runBlocking(Dispatchers.Unconfined) {
    // Started in main thread
    withContext(Dispatchers.Default) {
        // Working in DefaultDispatcher
    }
    // Back to main thread
}
