When using the Template Converter to convert a Importacular Classic to NXT, you may get the warning: 


  • The Constituent criteria set includes an Alias lookup. Alias matching is different in Importacular NXT so you may need to adjust your matching rules to reflect this change.

This means you will need to go into the associated Record Lookup and adjust your matching rule with an Alias Lookup to also include the Alias Type you what Importacular NXT to use. You don't have to make this change, but we think it will make your record lookup more accurate.
