How to upgrade from Eclipse Mars to Eclipse Neon?

To upgrade to a new version, the eclipse FAQ suggests to add a new repository and then install available updates. Upgrading to Neon, the corresponding repository is http://download.eclipse.org/releases/neon/.

On this page, it says:

NOTE: Due to structural changes you cannot update from a Mars (or prior) all-in-one package to a Neon version. If interested in the technical details, see bug 332989 and bug 490515.

I still tried to above procedure, but no updates were found. What is the best way to upgrade from Mars to Neon? A complete new installation? How do I preserve my settings?

It is not possible to upgrade from Mars (or earlier versions), so a new install is needed.

This can be in parallel with the old install. From the FAQ:

Fresh install

If you prefer not performing an update (for example because some 3rd-party content isn't ready for the current release of Eclipse IDE so the update reports conflicts), you can still download a fresh install of the Eclipse IDE and install it in another location on your filesystem, and use it together with the previous version.

To do so, download a new build from the Eclipse download Web site (https://www.eclipse.org/downloads/eclipse-packages/) and run the installer or unzip the archive in a new directory. We strongly recommend against installing/unzipping over your existing version of Eclipse IDE as it may corrupt your installation.

When you start a new version of Eclipse IDE, you can use the same existing workspace folder that you were using with older version. The workspace will be migrated to newer version and Eclipse IDE will to reuse all configuration. The workspace is forward compatible

The note on the repository page is right. Thanks to your report, I edited the FAQ to make it clear that upgrading packages from Mars to Neon is not supported.

Instead you need to to a fresh install for Neon (or later).

I tried to upgrade in the recommended way, by adding the repository links and doing an update, but then I got a lot of conflict messages. I foolishly tried to remove the conflicting software components, until it told me that Eclipse itself was the conflict! I posted my problem to the Eclipse Forums, and was told by a regular with tens of thousands of posts that Neon was so different that I should not even try to upgrade, just create a new installation. When I tried to do that however, I got lots of warnings "That the artifact download is progressing very slowly from ..."
