I am currently upgrading from SP1 to SP2 and am a little confused. In the SP2 Getting Started Guide and on techsupport (dont have the link) there is the suggestion (it is not clear to me whether MHF1 is a required initial upgrade before installing SP2) that MHF1 needs to be installed on top of SP1 prior to installing SP2.
As I have not installed MHF1 I am wondering if it is necessary. In any case, I think that I am going to install MHF1 first but it would be interesting to find out if there were any gremlins in the SP1 vanilla upgrade to SP2.
For those of us still buggering about with SP1 and thinking about SP2, there’s some good information in the following posts:
BOXIR2 SP2 - when to be released ? - not limited to release date.
and
BO XI R2 SP2 --> What’s in it?
Just an append to this: Release notes (xir2pp_releasenotes_en.pdf, pg 14, “Installation and Migration”) suggest that MHF1 is included with SP2 in the full installation.
