Can a WinCC OA project be copied from Windows to Linux?

A Windows-project can be used on Linux. The RAIMA-database is compatible. Maybe it is necessary at the Linux-system to set the config-entry useHeaderSize if the archives are not starting.

All panels/scripts/libraries are compatible. If you are using own CTRL-extension, own WinCC OA-drivers or own API-processes they have to be recompiled for Solaris.

If you are using ActiveX-objects at the panels those objects cannot be displayed on a Linux-UI.
