Merge update sets

You can merge multiple update sets into a single update set. This capability is supported for backward compatibility with earlier releases of the ServiceNow® Platform. The newer batch update sets feature accomplishes the same outcome with a more predictable and robust solution.

Before you begin

Note:

You can’t "unmerge" update sets once they’ve been merged. To learn more, see Update set batching.

Procedure

1. Navigate to All > System Update Sets > Merge Update Sets.
   By default, the list is filtered to only show update sets that are In progress.

   Alternatively, navigate to System Update Sets > Merge Completed Sets. By default, the list is filtered to only show update sets that are in the Complete state. For example, you may want to use this filter after pushing changes or transferring an update set from a development to a test instance.

2. Filter the list to show only the update set that you want to merge.
   You can only merge update sets that belong to the same application.

   Figure 1. Merge update sets

   

3. Enter a Name for the new update set.
   Updates are moved to this new update set during the merge process.
4. Optional: Enter a Description for the update set.
5. Select Merge.
6. In the confirmation dialog box, click OK.
   • The new update set is created.
   • The most recent change for each object is moved from the original sets to the new set. Only changes that aren’t merged into the new set remain in the original sets. A message indicates how many updates were moved and how many were skipped. For example, if both update sets modify the Incident form, only the most recent change is moved to the new update set. The other modification remains in its original update set to provide a record of the changes that weren’t moved.
     Note:

     The system determines which record is the most recent by comparing the Updated field for the records, NOT the sys_updated_on value in the payload.
7. Verify that the correct changes were moved to the new set by scrolling down to the Merged Update Sets related list and opening the old update set records.
8. Delete or empty the original update sets to avoid committing an older change by mistake.
   The system doesn’t remove updates that weren’t merged into the new set. Don’t move updates "left behind" in the old sets into the new set.
