Step7 5.5 to step7 5.6

Hello, We are migrating some wincc projects to 7.5sp1 and we will need to upgrade step7 5.5 to step7 5.6 sp1 because the wincc projects are configured in step7. We have a couple of 412-5H (firmware 6.0) installed and configured in step7. 

I can't seem to find a document or compatibility list to check if step7 5.6 sp1 is compatible with the 6.0 firmware. Right now I believe the most up to date firmware is 6.0.9 and i'm not sure if I will have to update all the cpu's firmware to the latest ones...

Thanks for your help!

Hi matwon,

I'm pretty sure you'll be good without upgrading firmware.

I have Step 7 v5.6 SP2 installed on my pc and firmware I get in hardware configuration is 6.0. Check the attachment.

Hopefully this helps
