when doing 'yum update' regularly this would also be EOL the end of the 
following year?

this is much longer here, can I update this 'forever' just doing 'yum 
update' regularly?

why I am asking this, I need to choose one option, because my CentOS 6 
VMs are EOL;

and I would practice this the same way I did, when my CentOS 4 became 
EOL, I installed CentOS 6
VM by VM - never used CentOS 5;

e.g. the first one was the DNS-VM, which I used CentOS 6.2,
then the outgoing Mail-server-VM, I used CentOS 6.3
and by doing 'yum update' regularly they all became finally 6.10;

so which should I choose
- CentOS 7: EOL in 2024
- CentOS Stream: EOL also in 2024
(CentOS 8 is no option I guess)

comparing to Windows,
when using Win10, there is no install needed any more, every half year 
function update,
and the other time security/bug fix update;

is doing CentOS Stream the same way?

Thanks,

Walter
