Hello, I have an issue when I migrate a Simatic WinCC Flexible 2008 SP5 project into TIA Portal.
When I migrate an HMI project into a TIA version higher than V12, this message appears:
"Device PANEL_HMI is not supported in this edition. Use an edition that supports device type MP 377 19''."

I searched for this message and found that TIA V12 is the highest version that accepts the HMI Panel MP 377.
So I tried to migrate the HMI project in TIA V12, but then this message appeared:
"The source project cannot be connected to the SQL server. The project may be opened by another application."

I searched in the community for a solution, but I couldn’t find one.

For extra information: SQL Server (WINCCPLUSMIG2008) is running in Services.
