I have a Dell PE2850 with two PV220s connected to a PERC 4/DC. There are 14 300 GB drives in each PV. I have 4 RAID 5 arrays of 7 drives each. Back up is to an HP LTO-3 tape drive.

I would like to use the Dell LTO-4-120 drive, which comes with an SAS PCIe controller card. Dell's recommendation is that I swap the riser card in the PE2850 with a PCIe one, and replace the PERC 4/DC with a PERC 4e/DC.

My question is: can I migrate from the PERC 4/DC to the PERC 4e/DC without losing any data on the 4 logical drives of roughtly 1.6 TB each?
