Upgrade Options
When you run the installer, you can choose the upgrade options and actions based on your current installation. When you choose a product to upgrade, the installer upgrades parent products as needed, and either installs or upgrades the product that you choose.
For example, if you choose Enterprise Data Catalog, the installer will upgrade the domain if it is running a previous version. If Enterprise Data Catalog is installed, the installer will upgrade it. If Enterprise Data Catalog is not installed, the installer will install it.
The following image illustrates the upgrade options and the different installer tasks for version 10.2.1:
After the installer performs an upgrade, you need to complete the upgrade of some application services within the Administrator tool.
