Operating System

Microsoft Windows Server Windows Server 2012 R2 (64-bit) or Windows Server 2016 (GUI, 64-bit), and PowerShell 3 or higher must be installed prior to installing West km.

The following components are installed with West km:

Internet Information Services (IIS) 8.5 (2012), 10.0 (2016)

Microsoft .NET Framework 4.6.2, 64-bit

Java Runtime Environment 1.8, 64-bit (8.0.101)

Oracle-inside-out-install 6.0 (HTML Conversion)

Vcredist2010 10.0.40219 (Cite Recognition)


Nssm 2.24.0 (Kibana)




Note: A secondary drive separate from the Operating System drive is requested for the installation of the West km software suite to accommodate Elastic search data, SQL, and logs.


System cryptography: Use FIPS compliant algorithms for encryption, hashing, and signing must be disabled.


IIS Components

Web Server
.NET Framework 4.5
Windows Authentication
WebDAV Authoring needs to be uninstalled


Database Management

By default, West km can be installed with SQL Express 2016. West km can also use an existing SQL Server instance with the configurations listed below:

-Microsoft SQL Server Standard or Enterprise Edition: 2016, 2014, 2012 (64-bit) AUTO_CREATE_STATISTICS set to ON for the West km databases
-Static port configuration required
-Cannot be installed on a domain controller

-High Availability/Always On must be turned off during installation (can be turned on post-installation)


Browser with Internet Access

Internet Explorer 11
Firefox current version
Chrome current version

Note: It is highly recommended that SSL (https) is used on the West km server to avoid allowing mixed content or unsafe scripts to run in the browser when Westlaw integration is being used. This requires that a security certificate be installed on the West km delivery server.

Note: Native XMLHTTP support must be enabled. To enable this feature, click Tools and then click Internet Options. Click the Advanced tab and scroll to the Security section. Ensure that the Enable XMLHTTP Support option is checked.


Firewall and Proxy Exceptions

All your West km servers must allow HTTP and port 80 access for outbound TCP communications through your firewall (specific addresses are available upon request). If you have a proxy server and utilize authentication, the West km server should be listed as an exception so it bypasses the proxy server. Proxy authentication is not supported.


Network Configuration

West km supports a multiple domain environment. For IWA (Integrated Windows Authentication), an LDAP connection string and network account with non-expiring password associated to each domain will need to be provided.


Antivirus Configuration

Configuration of your server in accordance with Microsoft knowledge base article 316148.


Statement of Compatibility for Virtual Environments

Support is provided for West km running on a virtual environment (e.g., VMware) without initially requiring reproduction of West km issues on native hardware. The virtual machines must meet minimum requirements.

If your West km technical consultant suspects that the virtualization layer is the root cause of an issue, you may be required to contact the appropriate support provider for your virtual environment to resolve the issue.

West km functional issues are rare under virtual environments, but performance and capacity issues are more common. Performance issues that deviate from internal benchmarks will require you to disable other systems that are competing for physical system resources and may possibly require you to remove West km from the virtual environment altogether.


Document Management System (DMS) Configuration

One item under each category is required and is the client's responsibility to provide.

Disk Space Calculations


Speak with your West km representative regarding recommended disk space based on your content and average document size.


Calculations should also take into account these considerations:

·        Growth: the number of years in the server cycle and the approximate number of new documents being added to West km per year.

·        Backup/recovery: the ability to perform backup and recover procedures on a server within a specified period of time.




Upgrades are not supported from West km 5.x and earlier. A new installation is required.
