Plone 5 Migration: ZEXP Export keeping translation links


i've been using Plone for a while now and for my experience the easiest way to migrate a website from Plone version to another is to export the Website over the ZMI as an ZEXP file and then import it in the new Plone.

The only flaw here is, that by doing so all Translation Links between the content languages get lost.
Is there any possibility to keep them as well?

Yours sincerely

Using ZEXP for migration purposes between Plone installations that are not identical is neither recommended nor supported unless you mean with "migrating" moving a Plone site to an identical installation.

So the logical answer: live with it.

You are doing migrations the wrong way.
