Platform upgrade complexity depends on the deployment. Upgrades for heavily customized deployments using many advanced features require far more care and planning than an upgrade for a sample evaluation deployment.
Make sure you plan and test appropriately before attempting to upgrade a production deployment.
To upgrade your sample deployment from 7.2 to 7.3, follow these high-level steps:
In the 7.2 deployment, configure AM base URL source services.
For details, refer to Adapt the AM configuration.
Upgrade the platform UIs.
Use the new UIs described in Set up the platform UIs.
For details, refer to Upgrade in the IG documentation.
For details, refer to Upgrade in the DS documentation.
For details, refer to Upgrade in the AM documentation.
For details, refer to Upgrade in the IDM documentation.
When upgrading from earlier versions of the sample deployment, also read Migration and customization.
