Hi everyone,

I hope this is the best place to post this question.

I was wondering how can one upgrade from CentOS 6.7 to CentOS 7.x using redhat-upgrade-tool-cli in a scenario where you're upgrading an Hyper-V based VM.

step1 would be to yum erase anything that didnt come from CentOS-6 itself, you clearly have external repos on there. And I mean not just remove the repos, but actually remove all the content that came from other places. Leave only content from base + updates for CentOS-6 itself.

secondly you need to use the centos tools from the centos repos
