TIA 10.5 project with TIA V11 / V12

Hello Denilson,

I have a problem that I believe it explained may help me. 

I'd like to know, what could I do if I have TIA v.11 and TIA 12 but a PLC that I want get upload is TIA 10.5?

I'm  but I couldnt do it. My PLC is Siemens CPU 1214C dc/dc/dc

I'll try to do it:

1. I'll get this old project that is V10.5.
2. Open in V11, without upgrading.
3. In accessible devices, find my PLC.
4. Select and copy all program blocks to your project-plc program blocks.

With your experience do you believe It will work? Have any risk to do it and I erase the PLC aplication?this aplication is running in a special machine, without backup.

Thanks Forward!
LFS
