Finally

I finally got Solution Manager to do what it promises to do and calculate the files needed for an upgrade of one of our SAP systems. Now, I'm faced with the task of actually upgrading the system. SAP seems to have a pretty nice tool for that: SAPehpi.  I went through guides and the main notes around it this morning got it running along. I'm sure the first attempt will result in failure, but I've got my backups and I'll keep my fingers crossed.
