Some questions

[eluser]Unknown[/eluser]
Hi there.
In my new company we'll start an important project. I have a Symfony background and wanted to use Codeigniter for this project.

My questions:
1. Our company already have a CMS for backend used in many other projects. I want to use that. Would that be a problem? I guess no. It's procedural code written years ago.

2. Is there a Propel like ORM layer or should we add it ourselves?

Thanks.
