Software upgrades and conversions
Software upgrades and conversions allow you to install new versions of the
Meridian Mail software without losing the data currently stored on the disk.
If, for instance, any of the DNs on the system you are upgrading have been
changed from the defaults, they will not be altered by the upgrade or conver-
sion process.
Software upgrades occur within the same release of Meridian Mail. For ex-
ample, if you are running Meridian Mail release 8, you might upgrade from
version 8.0 to version 8.1 and later to version 8.2. Such incremental updates
are released periodically by Northern Telecom to correct problems and im-
prove service, but they all share the same features and capabilities as the ini-
tial release of the product.
Software conversion is performed when Northern Telecom introduces a new
release of Meridian Mail, with new features and new capabilities. For exam-
ple, you must convert from Meridian Mail release 8 to Meridian Mail release
9, if you wish to take advantage of any of the new features available in that
new release.
What you need
• The new Meridian Mail software tape, NTAK72xE. (Refer to Table 2-1 on
page 2-2 for the exact part number).
• The new keycode for your system, if applicable. (Refer to Chapter 2.)
The keycode you need is printed on the label on the box containing the Me-
ridian Mail software tape, together with the serial number of the system. If
you are responsible for more than one Meridian Mail system, ensure that you
are using the correct keycode for each. If the serial number of the system does
not match that on the label, the keycode will be rejected.
