I know that when you setup Zen Cart you can choose a 'database prefix'. This would be 'zencart_' by default.

However, when I first installed Zen Cart I did not opt for this prefix. Now I want/need it!

How hard would it be to add this prefix?

So far I have planned to do the following:

1 - add prefix to all tables within database via phpmyadmin
2 - use dreamweaver to do a 'find and replace', which will allow me to add the prefix to all relevant bits of code in my php files.

Anything else I should consider?

BTW - I have a heavily modified store.

Thanks in advance.
