Hi Itlj, The problem with installing different versions is that only one database can be installed in the same environment. I mean, for example, two different versions of Unified-Unified, Professional-Unified, Professional-Professional or a version of WinCC Classic cannot coexist in the same environment. All these versions have a database and this will lead to problems. Therefore, you can install WinCC Advanced versions on the same virtual machine, as these do not have a database with a Unified version in your case, but you cannot install further Unified versions in the same environment. To install more Unified versions, you have to create virtual machines. I hope I have been able to explain myself clearly. Best regards!

Hello
Parallel installation of different versions (up to V19) of WinCC Professional / WinCC Advanced / WinCC Unified will not work. However, as @Murof posted above, it does work without WinCC Professional. So, for engineering (up to V19), it is possible to install different versions of WinCC Advanced / WinCC Unified in parallel. You can find the exact versions that are approved for parallel installations in the compatibility tool. https://support.industry.siemens.com/cs/at/en/view/64847781 Best regards, Costanza |
