It deceives people into thinking that there is a safe upgrade path from CentOS 6 to 7 when there is not and even with such a tool there will necessarily be a large amount of time and testing on a deployment that will be needed before one can safely switch a box over. This, imo, completely eliminates any gain you could get by using such a tool to upgrade vs simply doing a fresh install and porting your apps and data over because in either case you need a separate physical box, or VM and time and effort to make the change without interruption to existing services. The only way such a tool could ever make life easier on an admin is if it could do an in-place upgrade on a production server and any server admin who is crazy enough to even attempt such an endeavor should not be allowed anywhere near a server. You could make the argument that maybe such a tool could be useful for a workstation upgrade, but I find it's much easier and better to just keep a separate /home partition and just do a fresh install without reformatting /home. This would leave development servers as a potential target for such an upgrade, but what is the point of doing such a monumental task on a development server that you would not do on a production server? Shouldn't you be doing a fresh install like you would be doing on the production server instead? Did I miss anything or is there a really viable good use for such a tool that would make it worth the monumental effort to maintain it plus the bad karma from enticing lazy admins to try to use it? That said, if you want my opinion on how to fix it, my understanding is that the current problem with the tool is that there are packages in CentOS 6.7 that have a base version higher than the same packages in CentOS 7.1. My understanding is that yum is able to deal with this with the "distro-sync" command, so why isn't the upgrade tool making use of this functionality?
