It runs imperfectly by importing only one version instead of the whole versions of the source page.
See the log import in french Wikiquote or in french Wiktionary.
Version: unspecified

Transwiki import with full history is disabled due to performance issues, see https://wikitech.leuksman.com/index.php?title=Server_admin_log#September_20&oldid=16337 :
"14:45 Tim: re-enabled Special:Export with $wgExportAllowHistory=false. Please find some way of doing transwiki requests which doesn't involve crashing the site."

Seems to be limited to 1000 revisions currently (according to Krimpet):
<Mike_lifeguard> Is full history import still disabled?
<krimpet> Mike_lifeguard: I believe so
<krimpet> // 2008-09-29 putting it back on, with the history rev limit again -- brion
<krimpet> hmm. not quite
<krimpet> The current limit is 1000 revisions.
However, we do still need a way to get full history transwiki imports without crashing things.
