CentOS - Mar 2015 - Upgrade centos 6 to 7

I read at
<http://wiki.centos.org/TipsAndTricks/CentOSUpgradeTool>

"Warning: use of this tool is currently not recommended 
as several system-critical packages are of a higher version number 
in CentOS 6.6 than they are in CentOS 7 
so those do not get upgraded correctly. 
This renders yum and several other system tools non-functional."

Is that still the position?
If so, is it likely to change in the near future?

I would never, ever personally use this tool on a production server of
any kind.

That is a personal opinion.

I would also never, ever upgrade a Windows server from one major version
to another, etc.  I would always do a new install and migrate things to
the new server.  Just too many possible issues otherwise.  I feel that
the same is true for major Linux OS upgrades as well.

Several questions about the upcoming release:

  1.  Will this be happening WW14?  If not, is there an ETA?
  2.  We have our next minor release that?s dependent on CentOS7.1.  Are there
currently any ISOs available so we can do a risk build?  We have an extensive
automation farm and doing manual upgrades is not an option.

Thanks,
