Before you install your application, ensure that you complete all of the following tasks.

When completing the prerequisites for an installation, back up your system after each step to ensure that you can revert to the last good version of the system if you encounter an issue. For instructions, see Backing up your system.

1. Before starting an installation, and before backing up your system, review the database policies and application permissions that are used by your Pega Platform installation. Determine whether the application is permitted to update the database automatically or if you must generate the database scripts that your organization will use to manually make schema changes.

2. Install the latest version of Pega Platform 8.6, and ensure that you can log in as an administrator. For more information, see the Pega Platform Install Guide for your environment on the Deploy Pega Platform page.

3. Determine which language packs are applicable to your product and check for availability. For additional information, see Pega Marketplace.

4. Install Pega Foundation for Healthcare.

   Ensure that you install the Pega Foundation for Healthcare full application file and the sample data. For more information, see the Pega Foundation for Healthcare Installation Guide on the Pega Foundation for Healthcare product page.

5. Apply the required hotfixes by using Hotfix Manager. For more information about applying hotfixes, see Applying the latest on-premises patch.
