Several items off the Idea Exchange for NPC were updated this week & are coming in the next two releases. A couple of these will help make data migration/importing into NPC easier: 

Allow disabling of NPC program management validations status changed from In Development to Delivered

 Create Guest User license for Nonprofit Cloud status changed from Open to In Development

 Enable Path for Nonprofit Cloud and EdCloud Objects status changed from Open to In Development

 Allow to add more than 3 Gift designations on a gift entry status changed from Open to In Development

 NPC - Allow $0 Gift Transactions status changed from Open to In Development

Don't forget to vote for the ideas you want to see implemented in Nonprofit Cloud on the Idea Exchange!  We do review these regularly during release planning.
