If moving/migrating a show here's how to export your historical analytics.
This guide shows you how to export analytics from Omny Studio. In order to follow these steps yourself, you will need a user account with 'analytics' access.
Go to the program analytics page of the program you would like to export analytics from.
Select the date range. If you want to export total downloads from the program, select Lifetime.
Export to .csv.
Each analytics section has an export to .csv option. Click this to download a .csv format spreadsheet file with the analytics for this program for the date range selected.
Save these analytics to online storage or a backup to keep a historical record. This way, you can later add them to your destination feed and maintain a complete lifetime record of the program's analytics.
