How safe is it to delete the CoreStorage Logical Volume Group? Will all the data on the harddrive stay there?

And can I make a new CoreStorage Logical Volume Group for my harddrive and Fusion's SSD

Thanks in advance!
 
Since nobody reacts to my question, I started trying out things for myself. And after some searching, I completely reinstalled my mac with succes.

Here's what I concluded , maybe for other people with this problem ;

- Yes you can delete the CoreStorage (logical) Volume Group
- And, yes, you can re-enable the fusion drive. (CoreStorage (logical) Volume Group)
- Not possible when running OS X, you need to make a separate Recovery USB to load the recovery mode (This is deleted when you delete the all the CoreStorage)
- Simple walktrough on how to delete CoreStorage (split the Fusion Drive from the normal HDD) http://macs.about.com/od/diyguidesprojects/ss/Split-Your-Fusion-Drive-Apart.htm
- Re-enable the Fusion Drive http://macs.about.com/od/diyguidesprojects/ss/Setting-Up-A-Fusion-Drive-On-Your-Current-Mac.htm
