MSL2024 Robotic Partition reconfiguration

Hi,
I have a Query at a company running Backup Exec version 21.4  using an HP LTO tape library with two drives and 24 tape slots.  The previous IT guy is gone but left the partition with 14 partitions.  The first 1 -11 is a single partition and the rest of each has one slot, I need to change this configuration but I'm wondering what effect the changes would have on existing data that use the current partitions. will they update automatically?  I don't want to make changes with existing 12 to 24 individual partitions if reconfiguring the partitions and changing from 14 to 24 individual could cause problems or data loss. 1-11 don't have drives
