I was using Eclipse 2019-03 on macOS Mojave.
I wanted to upgrade to the recent Eclipse 2020-09, and retain my previous functionality that I had from installed components.

I used the Eclipse Installer, and I had no issues/problems identified during installation.

When I open the new Eclipse, it opens. When I specify my previously usable workspace, Eclipse indicates that it will modify the workspace and the workspace won't be usable with older versions of Eclipse. OK... However, when Eclipse then opens the workspace, it fails in that all of the view/editor windows in the workbench page are blank with errors like:
In the Package-Explorer: "Could not create the view: org.python.pydev.navigator.view".
In files which should be opened for editing: "No editor descriptor for id org.python.pydev.editor.PythonEditor"

I was assuming that the new Eclipse would be installed over the top of my pre-existing Eclipse configuration which also had python installed.
When I check under {About>InstallationDetails>Installed Software}, I can see that the New Eclipse version is missing "pyDev for Eclipse". So perhaps the Installer (despite being billed on the website as: "The easiest way to install and update your Eclipse Development Environment" ) doesn't really update, but rather just installs a fresh clean version...

So I guess my question is: is there an alternative way to UPGRADE Eclipse and retain all of my previous installed components. Or is that not possible or recommended?

Any help appreciated.
Thank you.

SOLVED:
For those interested, I followed the other upgrade instructions at: https://wiki.eclipse.org/FAQ_How_do_I_upgrade_Eclipse_IDE%3F

This actually seems to upgrade Eclipse and NOT do a fresh install.

I would suggest that the Eclipse Installer website change their verbiage from: "The easiest way to install and update your Eclipse Development Environment."
to:
"The easiest way to install your Eclipse Development Environment."
