Hi, How is the right procedure for upgrade the host from 4.0 to 4.1. I don't find any document with the right procedure, if i use the iso of the version 4.1 and i boot with this iso there is'nt the option on boot for upgrade. The problem is that it should be updated .repo file with the 4.1 release, but is supported ? How do you update the hosts ? Regards Massimo
