Hi,
I think this is a tough one, coz I'm trying to figure out how to import marketing lists as well..
The thing is that using Data Migration Tool, you can easily import related entities, but the case of leads and marketing lists is a bit different, because they're not directly related. I can see in SQL, that there is a table in the middle called ListMemberBase.
So I can get from SQL a list and create a csv file with all the leads data and the marketing list they belong to in a column, but when I want to import it, I can't find the way to relate the lead to a marketing list in CRM.
Any Ideas ?? The main question is: how to import a list of leads and marketing lists into CRM 4 so they are related??
