Upgrades and conversions

The ServiceNow platform includes tools to help you during and after an upgrade, and also allows you to convert a ServiceNow Express List instance to a ServiceNow Service Management enterprise platform.

The upgrade process moves your instance to a new ServiceNow release version. Understand the difference between upgrading and patching, release definitions, rollback and backup options, and how to test your non-production and production instance upgrades.

• Upgrade History module: Track every upgrade
  The Upgrade History module tracks every upgrade made to an instance. Administrators can use the module to resolve upgrade conflicts and optionally to revert customizations to base system versions to take advantage of new features.
• Upgrade Monitor module: Upgrade an individual instance
  The Upgrade Monitor helps you upgrade an individual instance. You can monitor the progress of an upgrade and resolve conflicts between the upgrade and customizations.
• Debug upgrade
  Diagnose and resolve issues you suspect may have resulted from the most recent upgrade by enabling upgrade debugging during a user session. Each transaction lists whether an artifact was skipped, customized by the customer, or modified by ServiceNow during the last family-to-family or patch version upgrade.
