Hey, If the question is still relevant, take a look at Data2CRM, an official Salesforce partner, to move the desired information from over 120 CRM solutions to any Salesforce edition or vise versa. That is, the service gives you an opportunity to migrate all the data with saved relations between transferred records automatically. Look at SaaS on Appexchange https://appexchange.salesforce.com/appxListingDetail?listingId=a0N3A00000EjVSuUAN
To check out Data2CRM in action, import a part of the current data to Salesforce for free by Running Demo migration. https://app.data2crm.com/wizard
