Moving from 1.0 to D2

[jicman]

Greetings and salutations...

I am corrently trying to get my co. to see the goodness of D.  So, we have a huge project, which is already live and 5 co-workers are using, which is all based on D1, if I may call it that.  The project also uses DFL, dbi (v.62) and juno (v.0.3.5.5), plus other libraries and DLL that I wrote, all based in D1.

How much different is D2 vs. D1?

Can the D1 code be easily changed to D2?  We are talking about more than 30K lines of code.

Any ideas?

thanks,
