Are you talking about source code level modifications for your application? The API for lcms 2 is different (much improved), but with some work there is a clear path. I just stripped lcms 1 support out of GraphicsMagick this past weekend since no one should be using it any more and because it complicates the code in a way which makes it difficult to take advantage of the improved features of lcms 2. When lcms 2 appeared, I took the approach to update the code to use lcms 2 and then back-port to still work with lcms 1. The reverse-patch at "http://hg.code.sf.net/p/graphicsmagick/code/diff/f11c2c4e798c/magick/profile.c"; should provide some idea of what was necessary in GraphicsMagick to provide a lcms 2 compliant implementation which still compiled and worked with lcms 1. The whole changeset (to take it out) is at "http://hg.code.sf.net/p/graphicsmagick/code/rev/f11c2c4e798c";. What you need to do for your application depends on what it uses lcms for.
