Hi,
That's right !
So, i had to make on the same disk an installation with preservation of AIX 5.2 ML4 and then upgrade to ML7.
And, it works not so fine as i have to reinstall some bundles.
But,...
I want to clone a AIX 5.2 system from a machine to another one.
So i modified bosinst.data and image.data files (according to future platform) before making mksysb on old platform....
