Upgrade Summary Report

The Upgrade Summary report summarizes the actions taken, provides tools to resolve conflicts between customizations and changes that are part of the upgrade, and provides information to help estimate time for upgrades to other instances.

Table 2. Skipped Records details

Field	Input Value
Total record changes	Total number of records that have changed since the previous upgrade version. Review changes: List of records that have changed can be reviewed. See System Upgrade form for more details.
Skipped records	Skipped records to prevent your customizations from being overwritten. If customizations are found in some records during the upgrade, those records are skipped. As an admin, you can resolve each update that was skipped due to a customization. To resolve a skipped update, you can review the reason for each skipped record and then either retain the customization or revert the customization to the base system. If you choose to revert some of the customizations to the base version, those records are sent through the upgrade without getting skipped. Total: Total skipped records To review: Total skipped records that are yet to be reviewed Reviewed: Total skipped records that have been reviewed
Skipped records by priority	ServiceNow prioritizes the skipped records based on the importance of the file types. The prioritization is done as follows: Priority 1 (highest priority): UI pages, UI macros, and more Priority 2: Business Rules, Security ACLs, and more Priority 3: Reports and more Priority 4: Form Sections, Choice Sets, and more Priority 5 (lowest priority): other
Skipped records by product	Skipped records are sorted by product names
Skipped records code changed/code unchanged	Skipped records are sorted depending on if there are changes in the code or not.

Note:

You can click Skipped Record VTB to view the resolution status of the current upgrade with skipped records using the visual task board (VTB) view. See Skipped Records visual task board (VTB) for more information.

Node Upgrades

The Node Upgrades section shows the status of the upgrade for each node in the instance. The color of the icon denotes the status, as illustrated by the legend (key) and to the right of the node icons. To see details about a node, position the cursor above the icon for that node. An arrow points to the node selected, and the information below the icons pertains to that node.

Application Upgrade Status

You can view the list of installed and upgraded applications during an upgrade. It also lists the applications that failed to install during the process.

Note:

The All applications are on the latest versions message shows up only when all the applications are on their latest versions.

You can view the first 10 applications that were installed during the upgrade. Select View all application details to view the information about all the installed, upgraded, and failed applications on the Upgrade App Version Histories table.

Note:

You can select any of the application links to go to its form view. Select Go to application on the form view to go to the application sys record.

The following message shows up if you have selected any of the failed applications link.

Schema Changes to Clone-excluded Tables

The Schema Changes to Clone-excluded Tables section shows a list of tables affected by the upgrade that were clone-excluded when you cloned the production instance to this instance. Because clone-excluded tables are empty, upgrading them takes less time than upgrading those same tables on the production instance. To estimate how much longer the production upgrade takes, note the size of the clone-excluded tables on the production instance.
