I have Eclipse 2.1.3 on my Windows XP machine and would also like to try
Eclipe 3.0.1. Can the two co-exist on this machine without messing each
other up?
What is the best way to install 3.0.1 without causing a clash with 2.1.3?
I'd like to be able to run either at any time. Will I be able to run both at
the same time if that becomes necessary?
What is involved in migrating projects over from 2.1.3 to 3.0.1, including
both Java projects and Tomcat projects?
Is there any functionality from 2.1.3 that isn't present in 3.0.1 or that
works very differently? For example, I seem to recall something about
plug-in development being different between the 2.x and 3.x streams but I'm
not presently developing plug-ins.

In addition to installing into a separate directory, you can just copy
over your 2.1 workspace into a new location and open that copied version
in 3.0. Eclipse 3 will automatically migrate the workspace, but once it
does so that workspace location can't be used by 2.x any more. So keep
the original 2.x workspace separate.
If you do this you may get some warnings the first time because the new
Eclipse version doesn't have all the same plugins as the old 2.x might
have. If that happens, just go through all the way, close all editors
and perspectives (maybe except for Resource Navigator), exit Eclipse and
restart. The second time it starts any warnings should be gone. You can
then re-open the perspectives you want and start editing files.
My installation looks like this:
Java/
Eclipse/
2.1/
3.0/
3.0.1/
workspaces/
2.1/
3.0/
3.0.1/
The workspaces/3.0 directory was originally just a copy of the
workspaces/2.1, and the 3.0.1 was originally a copy of the 3.0
I'm actually going to delete the 2.1 stuff this week, since I feel
comfortable enough with 3.0 and I don't want 2.1 hanging around any more
taking up disk space ;-) But this is my migration strategy every time,
so that I can always go back to the previous version if I want to.
HTH,
Eric
