According to https://www.eclipse.org/forums/index.php/t/1099758/, the only way to fully upgrade "Papyrus IDE" ( = the RCP corresponding to the current release) is to download it again and replace it manually with the older version. Unlike an typical Eclipse IDE, where I can upgrade the Eclipse IDE by adding the update site "http://download.eclipse.org/releases/latest/", Papyrus does not allow to upgrade it by adding an appropriate install/update-site. I can only add "https://download.eclipse.org/modeling/mdt/papyrus/updates/releases/2020-12" to update the papyrus modeling tools but this does not update its RCP.

Now my questions: Is it enough to download the whole Papyrus application and replace the app with the previous one? Will my old workspaces be compatible with the newer papyrus ide? What about my installed plugins and environment settings? Do I need to configure it again?

And the most important question:
Whould it be possible in the future, to also add the capability to upgrade the RCP of Papyrus by adding the appropriate update site? For example, by adding "http://download.eclipse.org/releases/latest/".

Ok I replaced the older Papyrus.app with the newer Papyrus.app and it works without problems. The only thing is: all the plugins and settings are lost.

So it would be good if Papyrus provides an update site to also update its RPC. Another alternative is to use a common eclipse installation and add Papyrus plugins there - with this, RPC and plugins can be updated in future without loosing all the previous settings.

Hi,
I think you're not on the right forum. Maybe you search https://www.eclipse.org/forums/index.php?t=thread&frm_id=121 ...

Hi

You can re-use the same workspace which is where nearly all the settings are.

As I replied on the JDT forum:

Quote:
Personally, I never use updates and so am guilty as a developer who doesn't test whether my projects are updatable or contribute to the overall utility. I see too much confusion and doubt and users with problems. P2 certainly has trouble if any of your applications has a feature evolution. And of course your chances of unupdating to determine why something worked on version X but not on version Y are very limited, particularly on a plane where the unupdate may be unable to redownload the old software even though you have the installations on disk and Eclipse has them in its plugins folder.

I always create a new installation from scratch, and use a Windows short cut to start Eclipse with the same defined workspace e.g. set my shortcut for 4.14 targets to:

E:\Tools\Eclipse\4.14\eclipse.exe -clean -data E:\Development\Rusa\Workspace -vm "%JAVA_HOME%\bin\javaw.exe" -vmargs -Xmx4g -XX:PermSize=100M -XX:MaxPermSize=300M -Xrunjdwp:server=y,transport=dt_socket,address=14143,suspend=n

Whenever you change Eclipse versions you get a warning that the Workspace was for a different Eclipse. Just click to continue. I have gone backwards and forwards many many times without problem. I really do not know what the point of the warning is; when there really is a problem there should be a migration. Of course taking a backup of the Workspace is a good idea and I used to do that but 5 years and many changes on I don't bother.

Running two Eclipses on the same Workspace is sensibly not allowed. Running two Eclipses with the same remote debug port (e.g. 14143) gives an obscure Java crash popup.
