The concept of upgrading and downgrading licenses is built into the Software Asset Management plugin
This is helpful when reconciling licenses. Downgrading a license is the process of purchasing a
license, but using an earlier version. Upgrading a license occurs when a newer version of a
license is not purchased, but you are allowed to use the newer version. Downgrading is more
common than upgrading.
Any version defined as a downgrade child that does not have entitlements and a license can be
counted as an installation of the upgrade parent. Use this method to avoid having to uninstall
unlicensed versions of software running in your environment. When you define an unlicensed
version as a downgrade child of a licensed version, the system creates a software model record
for the unlicensed version with an upgrade path to the licensed version. If you delete the
downgrade child from the licensed version's record, it is automatically deleted from the Software
Model record for the unlicensed version.
Note: If the downgrade child has either a
license or an entitlement, it must also have a counter, which counts all installations of the
downgrade child against its own license.
For example, you have licenses for the software model Microsoft Word 2010, but no licenses or
entitlements for Word 2007. Discovery finds
installations of Word 2007 being used in your organization. Rather than force users to uninstall
all instances of this unlicensed version, you decide to count installations of Word 2007 against
your Word 2010 license. To do this, you configure Word 2007 as a downgrade child in the Word 2010
Software Model record. A Software Model record is automatically created for Word 2007 which
specifies Word 2010 as the upgrade parent.
If a software version has a downgrade child or an upgrade version that can be counted against
the parent, the number of installs counted is restricted to the number of available rights of the
parent. For example, Microsoft Word 2010
has a downgrade to Word 2007. Both versions have an active counter. Microsoft Word 2010 finds all entitled copies
of Word 2007, and also takes out of compliance any installs from that downgrade counter until the
available downgrade rights are used. However, if Microsoft Word 2010 only has 100 rights, then
the maximum number of rights to be taken from the downgrade counter is 100.
You can set the start and end dates for a software upgrade parent and downgrade child to be
valid. The software counter counts the upgrade and downgrade licenses within the selected dates.
If the software counter runs outside of the date range, the upgrade and downgrade licenses are
Note: If an upgrade parent or downgrade child is set on the software model, it applies to all
licenses of that model. If set on the software license, it applies specifically to that
