[Solved]-How to properly upgrade Eclipse Indigo to Juno-eclipse

your better off using eclipse to reinstall the droid sdk again in your new eclipse; nevertheless, if you added the sdk as a dropin, its a simple matter of opening up the dropin directory and copying that to your new version of eclipse's dropin directory.

if it's anything like my android build it's in your plugin directory. i wouldn't suggest copying your plugin libs over to your new eclipse (ex: cp -rv ./eclipse/plugins/*droid* ./neweclipse/plugins > ~/copiedfiles.txt ), as i'm not 100% certain this way addresses startup issues or further xml configuration necessary for eclipse to behave properly.
