What is the order number (MLFB) of the New CPU you
want to use and also the version of STEP7 you are using?
Check if the new CPU can be programmed by current version of
STEP7 .
To do the changes, make a copy of the old project.Modify the
hardware (Keep the old settings for CPU and network) and then
compile it (you may loose the blocks here).Copy the blcoks
from original project the revised version.

Hope to be helpful.

I can see this CPU in my Hardware and I can create a new program with that, the problem was when I trying of change the CPU in an old project.
