About to up-convert a large CVI 6.1 project to CVI 2012. Any tricks/issues I should know first?

I am about to migrate an old project from LabWindows/CVI 6.1 on a Windows NT box into the modern & supportable age.  My target will be Windows 7.  Does anybody know any problems with doing this before I spend months doing something stupid? 

First attempt- CVI 2012 says the old "main.prj" file (from CVI 6.1) has "Incorrect format or corrupt data in file".  Not starting well.  Need smart guy help!

ThreedB,

CVI is, in fact, fully backwards compatible with code written in the past. The project file for your CVI 6.1 project should open properly in CVI 2012, and the API functions do not change between versions--if new functionality is added, we add new functions instead of changing the existing ones. Therefore, your code should continue to work in the latest version of CVI, and the migration should be quick and painless.

As for why your project file is saying it has corrupt data, I'm not sure why you would be seeing that error--while recreating the project file in CVI 2012 is definitely one troubleshooting step we can take to solve the problem, since this sounds like a big project we might be able to consider other ways of fixing it first. I'll send you a private message with instructions for how you can send me the project file.
