I promised on one of these groups, to dig into the issues with image conversion to Process 2012 in Lightroom 4. Here's the scoop, though its more complicated than expected; so this is a longer article than usual. But well worth it if you have any interest in managing images in Lightroom 4.

Nice explanation - thank you!

I discovered an interesting workaround to avoid the irreversible changes from Process 2010 to Process 2012. 

In a case where you're leery about updating the process version of a file that's seen a lot of careful work; make a virtual copy first. If you convert the virtual copy to the new process version, the process version of the original remains as it is. It's a simple matter then, of comparing the two images (original and virtual copy) and reproducing or improving the work that was done in LR 2 or 3.
