P7 8205-E6C upgrade to P8 8286-42A

I recently had our BP run a config for a P8 8286-42A based on my current P7 8205-E6C, 3 year warranty about to expire, 7x24 maintenance will increase significantly.
After reviewing the config, I realized the below current P7 features could be utilized in the new P8.
Actually, all my data could be moved simply by moving the EXP24S drawer, no need to unload/load.
Are there any reasons I shouldn't consider utilizing my current P7 features?

24 1962 571GB 10k RPM SAS SFF-2 Disk Drive (IBM i)
1 2893 PCIe 2-Line WAN w/Modem
2 5735 8 Gigabit PCI Express Dual Port Fibre Channel Adapter
3 5767 2-Port 10/100/1000 Base-TX Ethernet PCI Express Adapter
2 5887 EXP24S SFF Gen2-bay Drawer
4 5913 PCIe2 1.8GB Cache RAID SAS Adapter Tri-port 6Gb

Thank You
