Upgrade from 1.7.2 to 2.1.0

[eluser]Fred Riley[/eluser]
This is just to say a belated thanks for both of your replies, which are helpful. I'll give it a go with an earlier project I developed in 1.7. If I can't get the upgrade to work ok is it safe to keep the project in 1.7? Have there been any important security updates between 1.7 and 2.1, or would I just be losing out on extra features/classes if I didn't upgrade it.

I've been playing around today in 2.1 and there are significant coding differences that make me think that my old code might break if I upgraded to 2.1. For instance, the constructor call:

Code:

parent::Controller();

fails with a 500 error, and needs to be:

Code:

parent::__construct();

I've a feeling that there might be a few other bear traps to fall into.
