[Zope] Upgrade Zope from 2.3.2 to 2.4

[Gitte Wange]

Hello guys ...

I know I won't be the first to ask this question (or maybe I will *S*) ... 
but ..

I would like to upgrade our Zope installation from 2.3.2 to 2.4
The last time I upgraded there was a Zope-2.3.1-to-2.3.2 (or something like 
that) tarball I could get. This time there isn't. So how do I upgrade ?

Here is how I _THINK_ it should be done:
Copy the Products, Extension and var dir to somewhere else (as a backup).
Download the 2.4 tarball ..
Remove the old Zope dir
Untar the new tarball
Do whatever to install it.
Copy the Products, Extension and var dirs back
Start Zope

Am I right ??

Will our ZODB objects "survive" this ?

Regards,
