Why do I need to upgrade ?
But I will take all precautions .
So at the least problem I will restore FC5 . Two of the tricky things I am not sure of is setting up HPLIP correctly to get my PSC1315 working fine . Then I am also using Logical Volume Management . But I want to start with a clean slate and let Fedora assign the partitions etc.
. By May I will ask questions about FC7
