[Mediawiki-l] Upgrade from Mediawiki 1.6.5. to 1.15.1

[Sigbert Klinke]

Hi,

I'am running one Mediawiki with version 1.6.5. Recently I reinstalled
the computer and upgraded from PHP4 to PHP5. Therefore I can upgrade
from 1.6.5 to a more actual version of Mediawiki.

Can anyone tell me, if I should do it in one step? Or should I install
some intermediate version of Mediawiki?

Thanks in advance
