Hi Copperplated,
To upgrade your MSA2040 from GL210R004 I suugest youupgrade to GL220P010 first and then go to GL225P002-02. Be sure to follow best practices where you take a full backup of your data and perform the upgrade during a period of low host I/O. To optimize your system be sure to check whether your hard drives also need to be upgraded. You can use the following site for quick reference of drive firmware: https://support.hpe.com/hpsc/doc/public/display?docId=emr_na-c04315770&lang=en-us&cc=us
