Hello. It is good practice to backup your data before carrying out any maintenance tasks. Ensure that you have valid backup of your data. The PERC H710 P supports Virtual Disk migration from PERC H310 controller. As a best practice ensure that hard disks' and H710 P firmware is up to date . Replace the H310 and update the H710 P firmware with the controller cables disconnected from the back-plane. Power down the server and connect the controller cables to the back-plane and reboot. Your RAID configuration may either be transparent to the system or appear in a foreign configuration. Clear the foreign configuration through the OpenManage Server Administrator (OMSA) or Ctrl+ R utility during POST. Let me know how  it works for you.
Hello, I'm not an expert in RAID configurations but I'm in charge of my company's Dell T320 server and we're going to replace the storage controller that came with it (H310) with a PERC H710p. We have a RAID-1 configured and we're going to continue using the same two drives after the migration. We're going to replace the controllers. I know I have to do a backup before replacing doing the exchange but, are we going to lose the RAID-1 configuration and the data (including the OS) after migrating? Or is it going to be transparent to the system after rebooting? Where can I find some kind paper that could guide me thru this process because I don't want to screw anything up. Thanks a lot for your help. Jorge
