Is it possible to change the mount points without formatting the drive or reinstalling the OS?

Due to an emergency this morning,  I had to reinstall my OS.  I wasn't aware 
that I had to rename the mount points on my partitions when reinstalling; 
apparently I do.  I expected them to stay as they were before, because I was 
only working with the boot partition.

Currently the computer renamed them as /media/disk, /media/disk1, and 
/media/disk2.  This has caused me problems in the past, having /media as a 
mount point.  I have reconfigured and restored my computer the way it was 
before the re-installation, with a functioning OS again.  Since all my 
applications are properly configured and the  OS is working perfectly, is it 
possible to change my mount points on the partitions to /home, /home/backup, 
and /home/svpersonal without reinstalling the OS and applications again?
