Symfony 2 or Symfony 1.4?
I am starting a new Symfony project that will be very important to my company. My experience is only with Symfony 1.4. and I have 3 months to complete the project. 

The project should be around for years and will grow to have many features. I know that many people are already using Symfony 2 in production, but do you think it's a bad idea to go with 1.4?

Every situation is different. I don't see any problem with 1.4, but some people are suggesting I use Symfony 2 because eventually we will need to upgrade and do a lot of rewriting of code. 

Plus, there is Doctrine 2. I would be using 1.2.4. Again, I know that Doctrine 2 is really great, but am I going off a cliff by sticking with 1.2.4? It seems to do everything we need. 

Thanks for any insight.
