+# Migration Guide
+
+This is a guide for migration from version 2 to version 3 of zend-mvc.
+
+## Application
+
+The constructor signature of `Zend\Mvc\Application` has changed. Previously, it
+was:
+
+```php
+__construct($configuration, ServiceManager $serviceManager)
+```
+
+and internally, it pulled the services `EventManager`, `Request`, and `Response`
+from the provided `$serviceManager` during initialization.
+
+The new constructor signature is:
+
+```php
+__construct(
+    $configuration,
+    ServiceManager $serviceManager,
+    EventManager $events,
+    RequestInterface $request,
+    ResponseInterface $response
+)
+```
+
+making all dependencies explicit. The factory
+`Zend\Mvc\Service\ApplicationFactory` was updated to follow the new signature.
+
+This change should only affect users who are manually instantiating the
+`Application` instance.
+
+## EventManager initializer and ControllerManager event manager injection
+
+zend-mvc provides two mechanisms for injecting event managers into
+`EventManagerAware` objects. One is the "EventManagerAwareInitializer"
+registered in `Zend\Mvc\Service\ServiceManagerConfig`, and the other is internal
+logic in `Zend\Mvc\Controller\ControllerManager`. In both cases, the logic was
+updated due to changes in the v3 version of zend-eventmanager. 
+
+Previously each would check if the instance's `getEventManager()` method
+returned an event manager instance, and, if so, inject the shared event manager:
+
+```php
+$events = $instance->getEventManager();
+if ($events instanceof EventManagerInterface) {
+    $events->setSharedManager($container->get('SharedEventManager'));
+}
+```
+
+In zend-eventmanager v3, event manager's are now injected with the shared
+manager at instantiation, and no setter exists for providing the shared manager.
+As such, the above logic changed to:
+
+```php
+$events = $instance->getEventManager();
+if (! $events || ! $events->getSharedManager()) {
+    $instance->setEventManager($container->get('EventManager'));
+}
+```
+
+In other words, it re-injects with a new event manager instance if the instance
+pulled does not have a shared manager composed.
+
+This likely will not cause regressions in existing code, but may be something to
+be aware of if you were previously depending on lazy-loaded event manager
+state.
