Additional Notes

Deduplicate Assets - by Serial Number

Slider

When enabled, CI Sync will not synchronize each individual Lansweeper asset record as a separate CI, providing the individual asset records have the same serial number value. Instead, CI Sync the latest seen version of an asset by Serial Number will be synced only (the latest version) - any links or mappings to the previous asset will be released, allowing the newest asset to map to the existing CI in ServiceNow.

By default this setting is enabled for existing Syncfish customers from February 2026 and onwards.

By default this setting is disabled for existing Syncfish customers up to the end of January 2026.

  1. After modify the settings, scroll to the bottom of the page, tick the “I consent…” checkbox and finally click the Save connection button.

  2. You can now run a sync job and the amended settings will be applied causing the CI Sync Data Sync rules to be modified accordingly.

Importantly

Make sure you consciously override the setting against either your TEST or PROD environment (i.e. your TEST vs PROD sync jobs).

For more information on how to use TEST vs PROD Connection Settings please read Understanding the use of CI Sync Connection Settings.

Syncfish strongly recommend making changes for TEST environment/sync jobs first. Only modify PROD related settings after thoroughly validating the intended results in TEST.
