I'm considering upgrading from 3.55 to 4.0 in the very near future, and have a couple of quick questions.

I have several small projects in 3.55, what is involved in updating my code for 4.0? Most of the MySql-specfic code is hidden behind a common db interface, ie:
But there are still several places where I'm using MyDirect features. So, just wondering how much of that I'll have to review/re-code.

Second, can I run 3.55 and 4.0 side by side on the same development and user machines? If upgrading is trivial, this might not be an issue, but I may not have time to convert all my projects immediately, so I'd like to keep 3.55 around in case there are any problems.

Thanks,

Hello Michael,

The project should work ok.
Just remove the references in the project, close all running IDEs and help collections, then choose Uninstall MyDirect .NET v.3.55.
After that install a new version of the product (v. 4.50.27) and add references to the required libraries.
