Ensuring the server meets disk storage requirements for upgrades

You must ensure that you will have adequate disk storage before you start to install or replace software.

To make more efficient use of your storage, clear your system of items that you no longer require before you estimate how much storage you will need.

• Determining storage space required
  Before you schedule a time to install this release, determine the available storage space and the storage space that is required.
• Cleaning up disk storage space
  Cleaning up your system before you begin to install a new release makes more storage space available for the installation process.
