I think I will probably move up to Windows 8, but I may wait for SP1.
In any case, I see several options:
1) I can upgrade to Windows 8 'in-place' and it is supposed to migrate all my Win 7 apps.
2) I can create a new partition and do a clean install and then re-install all my apps.
3) I would like to do step 2 and then migrate the Win 7 stuff to the Win 8 stuff.
If I could do 3, I can try out Windows 8, maybe install X2a and see how it runs, etc.
But I don't know if migration is possibly, I've not heard of anyone that tried it or what software does it.
I have a rather customized set-up that I built from scratch and it took forever to install everything I had in Windows XP when I installed Windows 7. I'd like to not do that again.
I guess I could also do the dual-boot try-out and if I like it, I can removed the Win 8 partition and upgrade Win7 in-place. At least that would tell me that all my hardware drivers worked on Win8.
I think most of my critical stuff is all up-to-date and ready for Windows 8.
