Easiest way to upgrade eclipse 3.7 to 4.2 (Juno)

Question

So since Eclipse juno is based on 4.2 instead of 3.7, what is the easiest way to upgrade to it, short of installing a separate copy of juno and re-installing all my existing

Answer 1

Took me 2 minutes to migrate (longest part is the download ;)):

• Download the last release of eclipse : http://download.eclipse.org/eclipse/downloads/

• Extract the archive, launch the new version and select your existing workspace

• From the menu File -> Import

  • Select Install/From existing installation

  • It will let you choose which extension you want to keep (still compatible)

Note: I tested this manipulation from an Eclipse 4.2 to 4.3. I'm adding this answer because I think this solution is fast, easy and safe compared to the other answer.
