Hi James,
From an old email of mine to the list.
Hi Tony
Did you receive an answer to your question ? I didn't see anything on the list ! I'm interested too.
Thank you
No but I sorted it out myself. I just took a chance, it was on a test server anyway ;-)
In the disk partitioning screen you will see the old 6.5 installation. Clicking on it will bring up the existing 6.5 partitions. Then select each of the existing partitions and a configuration menu comes up which allows you to reformat the partition if required. So just don't reformat the partitions you want to keep .They then become part of the new 7.0 installation.
Hope this helps.
That is exactly what I ended up doing. It just seems a little odd to me to require that amount of manual effort when one wants to reuse the entire disk for a fresh install. I seem to recall that in 6.5 one could simply tell the installer to do exactly that.
In any case, somehow I experienced the situation that, even though I had 'deleted' each of the old mount points, the CentOS-7 installer would not reuse the original boot partition space but instead created a new one. I am not sure what was going on or what I did that caused this. In the end I rebooted from the liveCD and used the disk utility to manually remove all of the partitions on the HDD and then re-installed from the minimal DVD. That seems to have returned the partition table to something I am more comfortable with.
