You should open the existing dproj or prj file to convert these within the existing project.
But I am not able to find the prj file that goes with it. I was only able to find the schematic files (.1, .2, etc.. file extensions). I believe they were created using the Dashboard.
Is there still a way to convert them to the newer format?
Create a dummy .dproj file with the following two lines:
<projectfile version="1.0" name="YourProjectName">
Name it whatever you like and replace the "YourProjectName" with the name of the project file - you should then be able to open the project in VX.1.2
I believe the .dproj file extension is created when you are using the Dashboard to create a new project? However I don't use Dashboard. I only use the DxDesigner vx1.2 while creating a new project (.prj file extension).
If I am only using DxDesigner do I still have to do the same changes as you mentioned above? Could you also be little bit more explicit as to where those above changes (xml version = 1.0 etc...) have to be made? Also the dummy .dproj would have to be created using VX1.2 ?
The dproj file is the old project file extension from earlier versions of the software (pre-iCDB), Because PADS changed to this version later than Xpedition and didn't use the same naming conventions, PADS 2007 uses DxDesigner 2005 and it creates/uses the dproj file. Later versions of PADS switched to what was then known as the DxDesigner 2007 versions (iCDB) and used the prj file. You should create a dummy dproj file using a text editor, simply paste those two lines into it and save it as 'some file name'.dproj.
Then open this file from xDX Designer in VX.1.2.
If you can't make progress contact your local support organisation for assistance.
I created the .dproj as per your above instructions but when I try to open it from Vx1.2 I get the foll. error message: " Cannot find xDX Designer data- 'sym' directory is missing"
However if I change the file extension to .prj then I get the foll. error message: "Unable to open the project file"
What should I do next?
Without the original project used to create the schematics I don't know of a method to get the schematics into VX.1.2. You could review the information provided on the migration community pages, but I don't think this use case is covered.
