Can I open the *.UDX, *.UDF design files created using previous versions of PI Expert version 6.1?
You have two choices when opening an old (*.UDX, *.UDF) design file: – Review the file in read-only format with the PI Viewer. PI Viewer is also available within the PI Expert Tools menu. – Open the file and select the “Yes” option at the startup prompt to automatically convert to PI Expert version 6.1 *.UDS format. This file is no longer read-only and may be modified and re-saved. This conversion may modify the original *.UDX, *.UDF file contents. See “Opening a *.UDX, *.UDF file” for more information.
