The sequence you mentioned looks good. I would recommend to add 2.8.0 and 2.60.60.60 also to the sequence
I have a pair of PowerEdge R630s currently running VMWare ESXi 6.5. We are updating to ESXi 6.7 but I want to update the BIOS and iDRAC firmware first. Current BIOS: 2.5.5 Current iDRAC: 2.50.50.50 I was planning on updating the iDRAC first then the BIOS in the following succession: iDRAC 2.70.70.70 BIOS 2.10.5 iDRAC 2.83.83.83 BIOS 2.14.0 Am I skipping too many versions? Should I update the BIOS by each urgent release instead? This would be 7 updates per server.  Thanks!
