How to upgrade Eclipse from Galileo to Helios on Ubuntu (10.04)

From other related posts, the recommended "best practice" is to cr开发者_如何学Goeate a "parallel" installation of Eclipse 3.6 (Helios). But I wish it were that simple ...

On my system, the installation package for 3.5 (Galileo) seems to have distributed the Eclipse system files over many different file-system locations:

/usr/lib/eclipse
/usr/bin/eclipse
/usr/share/
/var/lib/dpkg/info/
/etc/eclipse.ini
~/.eclipse

It's not at all clear to me what a "parallel" installation would look like in this case. Can someone enlighten me?

Would I be better off just deleting everything other than my workspace files that appears to involve Eclipse, and try to do a clean install of Helios?

Thanks.

I, personally, always download the ZIP package of Eclipse from eclipse.org and don't use the system's Eclipse package at all. It just makes everything cleaner. Then, when upgrading, I delete the old Eclipse folder, unzip the new one, and maybe keep options in eclipse.ini. The only difficulty is with the plugins but I keep links to the update sites so it's no big deal to download and install them again.
