Installation guide

Also consider site performance—measure the time to acquire the first image. If current performance
is inadequate or borderline, this may be another reason to replace some of the equipment.
Note:
If upgrading a site using direct attached archives, refer to the AS300 Upgrade and DAA
Consolidation Guide—IMPAX 5.2 or 5.3 to IMPAX 6.5.3.
If upgrading a WEB1000-only site, you must install all IMPAX 6.5.3 software on new (or redeployed)
servers. You cannot upgrade WEB1000 servers to IMPAX 6.5.3 servers.
Assessing cluster configurations
(Topic number: 6723)
Then consider your cluster configuration. If currently using a standalone, single-server, or single-host
Server configuration, you could consider switching to a multi-host configuration (where each Server
component is installed on its own station) to improve performance. For supported upgrade
configurations, refer to Valid cluster configurations (refer to page 13).
If your site is part of a multi-cluster configuration, more study and report data will be coming
through than if it were not. Therefore, ensure that the cluster configuration you select will meet
these data requirements.
Defining Curator configuration
(Topic number: 9938)
The IMPAX Curator process is responsible for compressing incoming images into the Mitra Wavelet
format and storing them in the web cache. Wavelet images are displayed progressively, which often
results in faster image display. Curator is an optional component, but is beneficial for most sites.
You must decide whether to install Curator with other AS300 server components (for example, on
a Network Gateway station) or on a dedicated server. You can also distribute the load amongst
multiple Curator servers. For 5.2 and 5.3 upgrades, we recommend that the new Curator server be
used in the training server cluster during the preparing to upgrade period. Curator runs only on the
Windows operating system, not on Solaris.
For more Curator information, refer to the IMPAX 6.5.3 Curator and CD Export Server Installation
Guide and the Curator component of the IMPAX 6.5.3 Server Knowledge Base.
Communicating upgrade plans
(Topic number: 9924)
Upgrading a site to IMPAX 6.5.3 from IMPAX 5.3 or earlier is a big undertaking. Ensure that the
site personnel understand the major architectural differences between IMPAX 6.5.3 and IMPAX 5.3
