  Normally yes, unless you are using special firmware or hardware, such as GPU or NSX VIB or DPDK firmware. You can see VxRail Support Matrix to check which version of software/firmware included in specific VxRail versions and what is included in vxrail upgrade or not.  
Hi, I am planning to upgrade our vxrail cluster of 3 x e560 nodes from 4.7.526 to 7.0.320.   Can anyone tell me what the dependency on firmware upgrade is prior to performing a vxrail code upgrade?   Do we have any support matrix where it is clearly mentioned that from 4.7.526 to 7.0.320 requires an upgrade in Hops or can I upgrade without a firmware upgrade?   I have checked the support portal but I haven't found specific documents w.r.t dependency and prerequisite for upgrade.
