Relativity system requirements matrix
The following table breaks down the supported operating systems, framework, IIS versions, browsers, versions of SQL Server, and TLS (when applicable) for each of the still-supported versions of Relativity Server. For additional Chrome, Firefox, and Safari supported version details, see End user browser and operating system requirements
TLS protocol handling changed for Server 2026. Relativity delegates TLS negotiation to the operating system, and TLS 1.2 and 1.3 are supported. Disable TLS 1.0 and 1.1 on all Relativity servers. Do not disable TLS 1.2; some components, including Relativity Secret Store, require TLS 1.2. For more information, see the Pre-installation.
