Before Upgrading the OpenVMS VAX Operating System

5.1 Cautions and Restrictions

5.1.8 System Disk Cautions

The following cautions apply to the system disk:

• If you changed the names of system directories on your system disk, the

upgrade procedure will not work correctly. Restore your system disk to a

standard directory structure before you attempt an upgrade.

• You must not move the system disk or the distribution kit from one drive to

another during the upgrade.

• You cannot upgrade a shadowed system disk. If your system disk is part of a

shadow set, you must create a nonshadowed system disk before beginning the

upgrade.

Also, if you copy the distribution media to another disk, that disk must be a

nonshadowed disk.

For more information, refer to the manual Volume Shadowing for OpenVMS.

• If you elect not to install optional components, the upgrade procedure

removes existing ﬁles for those components from the system disk. You can

install optional ﬁles during the upgrade or later using VMSTAILOR.

Note that, while some optional ﬁles can be placed on an alternate device, you

cannot tailor ﬁles on or off an alternate device.

5.1.9 AUTOGEN Feedback Data

If you use your AUTOGEN feedback data, you should save this information

before rebooting the system with minimum startup to begin the upgrade. For

more information, see Section 5.3.

5.1.10 OpenVMS VAX Version Requirements

Before you can upgrade to OpenVMS VAX Version 7.3, your system must be

running at least Version 6.1 of the OpenVMS VAX operating system. For

example, you can upgrade a system disk to Version 7.3 of the OpenVMS VAX

operating system from any of the following versions (or related hardware

releases):

OpenVMS VAX Version 6.1

OpenVMS VAX Version 6.2

OpenVMS VAX Version 7.0

OpenVMS VAX Version 7.1

OpenVMS VAX Version 7.2

Note

These minimum requirements do not apply to rolling upgrades. There are

special considerations for rolling upgrades. See Section 6.1 for additional

information.
