Hello, i need help. Currently we have HMI 6av6 647-0ak11-3ax0. Because we do not have original project from WinCC, we make only back up with PRO Save. Question is: is it possible to use this backup on HMI with product number 6av2123-2db03-0ax0. Or if it is not, is there any alternative product for KTP 400 6av6 647-0ak11-3ax0 where we can use this backup file. Thank you.

Hello Christoph, thank you very much for your fast reply. Only doubt what i have is that on the product details for HMI 6av6 647-0ak11-3ax0 is written: The product was replaced with the following successor product - 6AV6647-0AK11-3AX1. Is that means that this HMI can be updated with backup file from 6av6 647-0ak11-3ax0 even if the product numbers are different?
