    This is the howto for people who wants to upgrade there CentOS 4 to 5.

    The only recommend upgrade option is from cd/dvd and locally in the datacenter. IT IS NOT RECOMMEND TO UPGRADE REMOTE WITH SSH (RESULTS IN PACKAGES CONFLICTS).

    ONLY FOR V11 USERS. CentOS 5 is not supported by V10

    For the upgrade must do the follow steps:
    1. Boot from cd/dvd
    2. choice the upgrade option and follow the steps.
    3. The first boot after upgrade: run yum upgrade
    4. reboot
    5. reinstall perl 5.8.8 (see package http://layer1.cpanel.net/perl588installer.tar.gz)
    6. run /scripts/upcp --force
    7. reboot (resolves services problems)
    8. reinstall apache (/scripts/easyapache)
    9. reinstall exim (/scripts/eximup --force)
    10. check all services if they running good.

    Centos 5.

    CentOS 4 isnt better. It is the same as CentOS 5 (stability). Only CentOS 5 has newer packages with new features.
