Chapter 2, Installing or upgrading an SCO system
Upgrading to the Enterprise configuration from Host or Desktop

Upgrading to the Enterprise configuration from Host or Desktop

If you purchased an upgrade for one of the following scenarios, the upgrade requires a two-step procedure:

The first step upgrades the system to SCO OpenServer Release 5.0.6 in the same configuration, and the second step upgrades the system to SCO OpenServer Enterprise System.

The first step happens automatically when you choose the Upgrade installation option. Use the license information from the previous (5.0.0, 5.0.2, 5.0.4, or 5.0.5) Certificate of License and Authenticity (COLA) for this step.

To complete the second step, follow the instructions in Chapter 4, ``Installing and managing software components'' to invoke the Software Manager and install the SCO OpenServer Enterprise System. When prompted, supply the license information from the 5.0.6 COLA.

After you install the SCO OpenServer Enterprise System, exit the Software Manager and reboot the system. 

Upgrading anonymous ftp from Desktop to Enterprise

When you upgrade an SCO OpenServer Release 5.0.6 Desktop System to an Enterprise System, anonymous ftp will no longer work if it was configured before. This is because the Enterprise System functionality that enables ``virtual domains'' prevents the ftp server from recognizing existing anonymous ftp user information.

To re-enable anonymous ftp in this environment:

  1. Back up the /etc/passwd file in a safe location.

  2. Edit the /etc/passwd file, changing the home directory entry of the ftp user to /usr/internet/ip/0.0.0.0/sco_ftp: 
    ftp:x:20:50:anonymous ftp account:/usr/internet/ip/0.0.0.0/sco_ftp:/bin/sh
    The ftp account entry must be on one line.

  3. Create a virtual domains stub directory:

    mkdir -p /usr/internet/ip/0.0.0.0

  4. Create a symbolic link from the stub directory to the original ftp home directory:

    ln -s /u/ftp /usr/internet/ip/0.0.0.0/sco_ftp

NOTE: Virtual domains are only available with a Fresh installation of the Enterprise system; see Chapter 27, ``Managing virtual domains'' for more information.



Upgrading the language product

If you upgrade the system within the SCO OpenServer family (for example, from Host to Enterprise), you must also install the appropriate language support product in the usual way, after the upgrade.

Ideally, do not install language products until after an upgrade.
