title: Migrate to Zend Framework 2 from Zend Framework 1
body: <p>We have pretty big application which has about 8 modules (big modules) written using Zend framework 1 and it has been developed for more than 3 years by couple of developers. Also it has a high traffic everyday. We use Amozon s3, Sphinx, Memcache, and some other third party services as well.</p>
  
  <p>Is it a good idea to migrate it to Zend framework 2 ? Because as we went through the doc briefly, it seems Zend framework 2 has been re-written completely. Therefore we think we won't be able to migrate the application easily rather than re-writing the application according to ZF 2.</p>
  
  <p>Valuable ideas would be highly appreciated.</p>
