VMware View Manager 4.5 Upgrade Manual page 8

VMware View Upgrade Guide
Until both View Connection Server and View Composer are upgraded, View Composer operations do not
work. If you have View Connection Server 4.5 and View Composer 1.0 or 2.0, users can connect to their
desktops, but no new linked-clone desktops can be created, and recompose, rebalance, and refresh operations
do not work. Also, you cannot edit settings for linked-clone pools.
I As the table shows, View Agent 3.1.x and 4.0.x are not compatible with View Composer 2.5. This
MPORTANT
limitation means that you must not use a View 4.0.x or 3.1.x master image, or snapshot, when creating,
recomposing, or refreshing a pool that uses features specific to View 4.5. These View 4.5 features include using
a system-disposable disk (SDD), using a Sysprep customization specification, and attaching a previously
archived user-data disk (UDD) to an existing desktop.
Although View Composer 2.5 can work with View Connection Server 4.0.x or 3.1.x in a limited fashion, this
setup is available only for cases where upgrading all View Connection Server instances during the same
maintenance window is not feasible. Specifically, new View Composer 2.5 features, such as the ability to use
SysPrep customization, are not available until you update to View Agent 4.5.
Because View Client with Local Mode is a View 4.5 feature, and its predecessor, Offline Desktop, was an
experimental feature, View Client with Local Mode is not backward compatible with View 4.0.x and 3.1.x
components.
N The instructions in this document are also applicable to patch releases of VMware View 4.5 and to
OTE
upgrading from the release candidate (RC) version of View 4.5 to the general availability (GA) version.
