Hello,   I agree firmware on array first.  Remove MEM, then upgrade vSphere server to v6 then ESXi nodes to v6.0.  You can do MEM or VSM in any order at that point.    Regards,   Don 
Hello, I now see that EQL v8, MEM 1.3 and VSM 4.5 have been released as EPA so I can upgrade to vSphere 6!   Is there a recommended upgrade order for all of these components?  I would imagine EQL v8 first, then the vSphere environment, then MEM, then VSM? I believe I read MEM 1.2 wasn't compatible with vSphere 6?  If thats the case, I would imagine I have to switch to RR before upgrading vSphere and then apply MEM 1.3? Thanks in advance!
EQL / VSM / MEM / vSphere Upgrade Order
