Thank you Leo for pointing to my post

 

Those iso files are direct downloads from cisco.com. You do not want any application to make it a iso files. See below post.

You can go "straight" upgrade from 3.X to 4.X.  

NOTE:  

If you read the Release Notes, the procedure to upgrade the CIMC firmware is incomplete and confusing.  @Rasika Nayanajith has knocked up a detailed step-by-step process (LINK) that I find very useful.  

WARNING

CIMC upgrade can take, on average, 70 minutes.  During this time, the server is off.  

Hi,

 

Thank you for this guide, i will try it now.
