  The silvaupdate script and clicking on the button "upgrade content"
  does exactly the same thing (those are just two entry points to the
  same exact code). The script is more secure as you are sure that
  nobody access your site before the migration is over (Zope is
  started, but does not listen for HTTP requests).

  That's possible. We don't use that anymore, and it is mark obsolete.
  We now implement all the skins using silva.core.layout.

  In Silva 3.0 that Legacy layout feature will be gone.

 I think here you did an export in ZMI using ZEXP feature. I have never
 use the XML export for ZEXP, it is possible it changed in Zope.

 This feature is a Zope feature, that Silva doesn't use, or rely on it.
