I read in <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." Does this still hold? It seems to me a bit pointless to offer a tool with the warning that it does not work. -- Timothy Murphy gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin

I would not use it. To each their own. The best way to do any major update is to backup your data, install the OS, bring back your data and make all the newer services (if you are moving things like databases or web directories, etc.). Some people want to take shortcuts to this procedure, and with enough effort, that tool can work. But to me, there is too much effort and there are too many older packages left around as clutter, so I would never do it. It can be done, however. Red Hat released this, so we rebuilt it .. that does not mean one should use it. Thanks, Johnny Hughes -------------- next part -------------- A non-text attachment was scrubbed...

You are doing a fantastic job. However, I find your answer here a little odd. It's a bit like the surgeon saying, "I wouldn't have this operation, but if you want it just lie back."> The best way to do any major update is to backup your data, install the > OS, bring back your data and make all the newer services (if you are > moving things like databases or web directories, etc.). > > Some people want to take shortcuts to this procedure, and with enough > effort, that tool can work.
