Possible to build an update site from 3.2 for 3.4? [message #329360]

Is it possible to build an update site from 3.3 such that when installing
it into 3.4 you don't have to go through the old update manager?

We have a plugin about to be released that we build with 3.3.2. We would
like our users not to have to jump through the hoops to install/uninstall
using the old update manager in 3.4 (although, we very much appreciate
that it is there!).

Should we provide two installations, one for 3.3.2 built on 3.3.2, and one
for 3.4 built on 3.4?

What is everybody else doing?

The new p2 update mechanism can handle the old update site format, so
you don't really have to change it to accommodate 3.4 users. However,
the p2 team seems to strongly recommend that you move to the new format
because apparently p2 is a lot more efficient that way.
All the info you need is probably available from here:
http://wiki.eclipse.org/Equinox_p2

Hope this helps,
Eric

To be clear, the "new format" adds some extra files to the site, but
doesn't alter the existing site.xml or other files. Thus a p2 repository
and Update Manager site can coexist at the same URL.
