IDEA 4.5 & 5 Follow
I want to start a new project in IDEA 5, but at the same time I'm not ready to upgrade any of the ongoing projects. Can 4.5 & 5 coexist on the same system?

Hello Dmitry,
DB> Can 4.5 & 5 coexist on the same system?
Yes.
Just make sure they don't use the same config and system directories - by
default it seems that it is so: /bin/idea.properties in 5.0 points
to ${user.home}/.IntelliJIdea50/... that shouldn't be in use by idea 4.x
Just to make doubly sure, make a backup of your config and system directories.
