This topic describes
in greater detail how the SAS Deployment Wizard adds, updates, and
upgrades SAS software.
The wizard compares
the release version of the SAS software in the current order to the
SAS software that is deployed on the machine. Three possibilities
exist:
-
The software in the order has a
newer release
level than the software deployed on the machine.
-
The software in the order has an
older release
level than the software deployed on the machine.
-
The software in the order has an
identical release
level as the software deployed on the machine.
Upgrades and updates
consist of a new version or an incremental delta update (also referred
to as maintenance) to an installed product. If the deployment wizard
detects that one or more products in the order have a
newer release
level than any products deployed in the specified SAS Home on the
machine, the wizard goes into Update mode. (SAS Home is shorthand
for the SAS installation directory (for example,
C:\Program
Files\SAS
). The wizard displays an updates page of
all the products deployed on the machine for which there are updates
in the current order.
The deployment wizard
updates page is broken into two sections that list new product versions
and new product delta updates (or maintenance). In the example of
the updates page shown earlier, SAS Providers for OLE DB (64–bit)
represents a new product version (for example, 9.3 to 9.31). SAS Threaded
Kernel Core Routines (64–bit) represents a delta update (for
example, 9.3 to 9.31_M1). If you choose to proceed with your deployment
from this order, to the specified SAS Home, the wizard requires that
you install these updates to bring your existing deployment to the
release level from which your new order was mastered. When you click
Next,
the wizard automatically upgrades the products to the release levels
that are shown on the updates page.
When running in Update
mode, the wizard displays no deployment plan, SAS installation data
file, or language pages down this path. The wizard simply installs
the newest versions and delta updates of the product set already deployed
in the specified SAS Home. If the update contains updated language
support for a specific product (such as, SAS, SAS Enterprise Guide,
and SAS Add-In for Microsoft Office), the wizard installs only the
update for the languages previously installed. If you are adding new
products or language support to an existing SAS deployment, you will
install those in an additional SAS Deployment Wizard session, after
the update is installed and any customization or validation is performed.
If the deployment wizard
detects that one or more products in the software order has an
older release
level than any products deployed in the specified SAS Home on the
machine, the wizard does
not go
into Update mode. Instead, the wizard presents you with an alert box
listing those products in your order that are older than the ones
deployed on your machine.
SAS wants to make sure
that you are always installing software from an order corresponding
to a release level that is identical to or newer than the one used
to originally deploy your SAS software. Your options are to use a
different software order, designate a different SAS Home directory,
or uninstall the products that are newer.
If the deployment wizard
detects that all the products in the order have an
identical release
level to all products deployed in the specified SAS Home on the machine,
the wizard does
not go into
Update mode. Instead, the wizard presents pages that enable you to
perform normal deployment tasks such as deploying products, installing
additional software, and so on.

summarizes how the SAS Deployment Wizard manages deploying products,
installing additional software, and applying updates:
