I am planning to update the firmware on a Dell Equallogic PS 6100. It is currently running firmware version 7.1.5. I went onto eqlsupport.dell.com to get the .zip file to upload the firmware update. I see the have three versions listed as recommended ps series firmware: 10.0.3, 9.1.9, and 8.1.15. I also see there is a section called Legacy version. Do I need to go to the legacy versions and start with version 7.1.7 or can I do one of the recommended ones such as 10.0.3, 9.1.9, and 8.1.15? 

 

I did verify there is no replication on the SANs and the available storage space is good. I just want to make sure I am well planned for updating the firmware.
