Appreciate your help to get a fix for this issue.

PS. Please note that this was working fine in Oxygen before I upgrade to Photon.
Thanks,

Hi,

I never had this problem with photon (which is already quite old). How did you migrate from oxygen? Can you try to setup Eclipse photon from scratch? Is it an option for you to use a current Eclipse version?

Hi Ansgar,

My intention in the begining was to upgrade Oxygen rather then to go with an Install of Photon from scratch as I don't want to lose my current projects and the procedure I followed is
1- Added http://download.eclipse.org/releases/photon site Under Preferences -> Install/Update -> Available Software Sites
2- I went to Help -> Check for Updates.

If I'm not able to solve this issue definitely I will go with a fresh install of Eclipse 2020-03.

Thanks,
/Kamel

Hi Kamel,
I highly recommend to always do a fresh installation of any Eclipse based IDE with a new, fresh workspace folder.
And import the projects to be used with the new release into the newly created workspace. Please do not forget to set the copy switch.
Following this procedure will keep the old installation completely untouched. Consequently you can use the old installation as fall back until you have completely validated the new installation.
The ability to set up a new installation while preserving the existing one is an IHMO big plus of Eclipse over most commercial IDEs. With IBM Rational Rhapsody for example I do a complete backup before installing a new release.

Hi Ansgar and Carsten,

I have done a fresh install of eclipse 2020-03 using the installer, now the issue of creating a new papyrus model or opening the papyrus models from my old projects is fixed. however I noticed that the modeling perspective is not shown under perspectives.

What is the eclipse plugin responsible for that? I have Eclipse Modeling Framework SDK already installed.

Any idea on how to get it back.

Hi Kamel,
"Eclipse Modeling Framework SDK" ist not Papyrus. Either you get the Papyrus all-in-one package or you have to install Papyrus on top of "Eclipse Modeling Framework SDK".

Hi Carsten,

After Eclispe 2020-03 fresh install, I have installed Papyrus plugin for Eclipse 202-03 (http://download.eclipse.org/modeling/mdt/papyrus/updates/releases/2020-03).

I'm attaching my eclipse perspectives.

Before I had Modeling perspective, don't understand why now is not appearing in the list of perspectives.

Thanks,

Hi Carsten,

I have fixed my issue. Now I can see Modeling perspective in my eclipse perspectives list.
Basically I have installed Ecore Project modeling plugin for Eclipse 2020-03 on top of EMF SDK and after a restart it is added.

Thanks for your guidance.
