Posted on 2011-10-13

Hi, I have a dedicated server and need to upgrade from Centos 4 to centos 5 in order to get automatic updates for new software. I was told that I need to get a new server in order get the operating system upgrade. I currently have an Intel Xeon 2.66ghz.

Is a new server really necessary? The current one is performing well for me. Why would my hosting company have this policy and is it a widespread policy among dedicated web hosting companies?

thanks for your help!

    No.  You need proxy or Satellite server which for CentOS is SpaceWalk only when you have a huge environment in your server farm.

    For a couple of servers you can configure it to access the central repositories

    If you have a large server farm it makes sense to get the upgrades to only one machine and the to redistribute upgrades from there.

    Upgrading within revisions just works -- upgrading versions typically requires a new installation.

    I think the asker is asking about a lot of upgrading and patching that the system administrators have to do on daily basis.  Linux works really well with these upgrades and in particular Redhat/CentOS do really well.  The only time a reinstall is better -- when you have to upgrade from RHEL4 to RHEL5 but with even that some system admins make it work well.  If you are managing 1,000-10,000 servers, simply reinstalling for every upgrade doesn't make sense.

    OK going by strictly what the asker said, which I read as his hosting company is requiring him to upgrade to a new /  more powerful dedicated server in order to support a CentOS 5 install.

    No, a new server is most definitely not necessary.  If the 2.66Ghz cpu is currently performing well for you, then it will also perform well for you in CentOS 5.

    If your hosting provider is forcing that on you, then find a new hosting provider as that is a ridiculous requirement.

    Papertrip, that is exactly what I meant with my question. This policy sounded very awkward, and I wanted to know if others felt the same way.
