The following CVM network shows you the detailed steps of upgrading CentOS6.4 to 7.0:

Step one:

1] configure the software source

# vim / etc/yum.repos.d/upgrade.repo

[upgrade]

Name=upgrade

Baseurl= http://dev.centos.org/centos/6/upg/x86_64/

Enable=1

Gpgcheck=0

[2] install software tools

Yum-y install preupgrade-assistant-contents redhat-upgrade-tool preupgrade-assistant

[3] check for potential problems before upgrading

# preupg

Preupg tool doesn't do the actual upgrade.

Please ensure you have backed up your system and/or data in the event of a failed upgrade

That would require a full re-install of the system from installation media.Do you want to continue? Y/n

Result table with checks and their results for main contents:

-

| | System kickstart | notapplicable |

| | YUM | notapplicable |

| | Check for usage of dangerous range of UID/GIDs | notapplicable |

| | Incorrect usage of reserved UID/GIDs | notapplicable |

| | NIS ypbind config files back-up | notapplicable |

| | NIS Makefile back-up | notapplicable |

| | NIS server maps check | notapplicable |

| | NIS server MAXUID and MAXGID limits check | notapplicable |

| | NIS server config file back-up | notapplicable |

Tarball with results is stored here / root/preupgrade-results/preupg_results-140716022514.tar.gz.

The latest assessment is stored in directory / root/preupgrade.

Upload results to UI by command:

E.g. Preupg-u http://127.0.0.1:8099/submit/-r / root/preupgrade-results/preupg_results-*.tar.gz.

[4] start upgrading

# rpm-- import http://centos.excellmedia.net/7.0.1406/os/x86_64/RPM-GPG-KEY-CentOS-7

Normal operation of the above command can be upgraded to complete

# redhat-upgrade-tool-- network 7.0-- instrepo http://centos.excellmedia.net/7.0.1406/os/x86_64/

This compulsory one seems a little unfriendly, and the production environment should be used with caution.
