At present, on C220 M3 rack server , running firmware version is 1.5 (4e). We wish to upgrade it to 2.0(13f) version (both CIMC and Bios). As per this URL,
http://www.cisco.com/c/en/us/td/docs/unified_computing/ucs/c/sw/lomug/2-0-x/b_huu_2_0_3/b_huu_2_0_3_chapter_010.html
we have checked that for 2.0(3) upgrade on C220, 1.5(4e) is the minimum requirement. But I am unable to find minimum requirement for 2.0 (13f).
Kindly suggest what should be the correct upgrade path for 2.0 (13f). It should be direct from 1.5 (4e) or any intermediate firmware is suggested.
