• Due to Highrise API restrictions, we can only export "open" Tasks which are visible to the current user and related to either a person, a company, case or a deal. If you need all of your tasks to be migrated, please send us a message to review the possibilities. 
• Private Tasks can be migrated, but requires a customization to do so. 
• Attachments can be exported, but only from emails and notes
• "Remember the date" for Contacts is not supported at this time
