Dears,

I have a project created in PCS7 v6.0 and I need to upgrade it to the latest version PCS7 v9.1 while keeping the CFC logic and SCADA faceplates and block icons without change

I read the upgrade manual and started by trying to upgrade to V7.1, but when I try to compile in V7.1, I get an error message "Block Data Section Does Not Exist" (attached screen shot)

I have only the option to compile entire project because the other option of compiling changes only is dimmed.

Note that when I open the same project in V6, I have the compile changes only option available

The compile log is below:
