CentOS 6 will end of life in Q2 2017

According to the official CentOS web site, CentOS 6 supports will going down in Q2 of this year. Migration time is being remain less than four months soon. In addition, there are no safety, proved offical ways for In-place upgrade process. The Arch. of CentOS 7 has big big big different from version 6. Therefore, parallel migration might be the one and only one method we could choose for.

I have two CentOS 6.x machines. Both major services are SFTP/FTP and Virtual Web Site that managed by Virtualmin system. THe migration process should be going fine. For long-term consideration, move all web sites towards any HA arch. could archive better management ability, especially upgrading the bae elemets surrounding the operating system issues.
