The following figure shows the supported upgrade path for TrueSight Orchestration Platform. Ensure that you are upgrading from one of the versions shown in the figure.

ErrorWarning
- Do not change the authentication system type while upgrading.
- You must use the same authentication system (embedded or external) as used in your current platform environment. If your current platform environment uses embedded Remedy Single Sign-On (Remedy SSO), do not switch to an external Remedy SSO or from an external to embedded Remedy SSO.

WarningImportant
- BMC Remedy Single Sign-On (external and embedded) is used as the authentication system.
- If you want to use an external Remedy SSO, you must first install or upgrade to a supported version before upgrading the TrueSight Orchestration Platform. For more information, see System-requirements.
- If your current platform environment uses embedded Remedy SSO, when you upgrade to 24.3.00, the embedded Remedy SSO version is upgraded to 20.02.01.
