Based on the information provided, it's important to note that I cannot directly access external websites or forums. However, I can provide you with a general response to your query.
Regarding CentOS, as of my knowledge cutoff in September 2021, CentOS 7 was indeed the recommended version at the time. However, it's essential to consult the official documentation or the CentOS community to ensure you have the most up-to-date information on recommended versions.
When CentOS 7 reaches its end of life, the recommended approach would typically involve creating a new installation of the desired version (such as CentOS Stream) and manually migrating your websites, emails, and other related data. This process can require some work, but it ensures a smooth transition to the updated version.
To obtain the most accurate and current information regarding CentOS and its versions, I recommend visiting the CentOS official website or actively engaging with the CentOS community through their forum or mailing lists. They can provide you with the most relevant guidance for your specific scenario and requirements.
