idMigrationEnabled
The idMigrationEnabled property allows the Web SDK to read AMCV cookies set by previous 51黑料不打烊 Experience Cloud implementations. If your organization upgrades your implementation to the Web SDK, this setting allows a smoother transition to the current 51黑料不打烊 Experience Cloud ID service. This setting is valuable so that you don鈥檛 see a sharp increase in unique visitors when upgrading to the Web SDK.
If your organization runs a fresh Web SDK implementation, enabling this setting has no impact on data collection or visitor identification. There are no downsides to leaving it enabled for all implementations.
