Migrating a RAID array from a PERC 4/DC to a PERC 4e/DC

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?

Good question, and you should be asking this of DELL, since it is their hardware.

Escalate this as high as you need to get an answer from a senior tech.

I would think that it should work, but  would not depend on it.

You may need specific firmware upgrades to make them more compatible.

I hope this helps !

To close the loop on my original question, and in case it helps anyone else:

I ended up ordering a new riser card from Dell. As it turns out, it came with one PCI-X socket and two PCIe sockets, so I was able to reuse the PERC 4/DC without fear of disturbing the RAID configuration.

The SAS PCIe controller card for the LTO-4-120 drive is installed in one of the PCIe sockets, and everything is working as I had hoped it would.

Please don't accept a post that explains how to close a Q. Either Accept one that makes some sense, or ask in Community Support for it to be closed, like it says in my earlier Link. I'll reopen this Q so you can close it properly.
