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!
