We’ve upgraded some SLES servers from 9.x to 10.x and over to 11.x. And I suspect that there is a lot of orphan packages laying around.
I know that with SLES 12 there’s a option in zypper for it. Does something like that exist in SLES 11?
And by orphan, I mean packages installed that are not in any of the current repositories. Packages that existed in 9 does not always exist in 11.
