In addition to move your account you can export and import the list of accounts you follow. The exported list is stored as CSV file that is compatible to the format used by other platforms as e.g. Mastodon or Pleroma.
To import contacts from a CSV file, go to the Settings page. At the bottom of the account settings page you'll find the import contacts section. Upload the CSV file there.
The CSV file must contain at least one column. In the first column the table should contain either the handle or URL of an followed account. (one account per row.) Other columns in the CSV file will be ignored.
