Reconfiguring Disk Storage Area

We are using Backup Exec 2012 and currently have our disk storage area as a 10TB RAID10 connected so a SAS controller. We have about 8TB of Backups on this. All of these backups have been duplicated to tape. We need to reconfigure the Disk into two 10TB RAID6's which means blowing away all the data on it. I'm not worried about losing the data as we have it on tape. Is there anything I need to be aware of when doing this such as what happens with the BE catalog database?

Any help greatly appriciated.
