The sync is one-way, from Lansweeper On-premises to Lansweeper Sites. Any changes to your custom fields in your Lansweeper Site are currently NOT synced back to your on-prem installation.
Synchronizing your Lansweeper On-premises custom fields with Lansweeper Sites enhances asset management, offering increased flexibility and control. This process allows you to include custom fields in views, reports, and API-based integrations without field limits. This feature is beneficial if you’re using both Lansweeper On-premises and Lansweeper Sites, as it enables you to automate asset data migration and allows day-to-day operations to shift smoothly to Lansweeper Sites.
Enabling custom field synchronization is irreversible. After enabling custom field sync, it cannot be disabled. Once the fields are synced, you can view and manage them within your Lansweeper Site.
