将Azure Openlogic CentOS 6.7升级到CentOS7.2的最佳方法是什么？它与CentOS 7.2图像类似。 我做了sudo yum更新，但它没有升级到最新版本。有些人可以提供升级到最新主要版本的步骤

我建议使用CentOS 7.2模板部署新操作系统，然后从旧虚拟机迁移数据和配置。
就地升级容易出错。目前，CentOS的官方网站也没有建议从6到7的就地升级。
DO NOT USE this tool. Warning: use of this tool is currently BROKEN as several system-critical packages are of a higher version number in CentOS 6.7 than they are in CentOS 7 so those do not get upgraded correctly. This renders yum and several other system tools non-functional.
