How can I import Memberships without membership start date?

Question

I want to import membership in update mode and I don't have start_date so at the time of import it shows me start_date is required field. I have removed membership_start_date required field from /civicrm/CRM/Member/Import/Form/MapField.php file after that it is giving me error-

Invalid value for field(s) : Membership Start Date is required to create a memberships.; Start Date" in import_error.csv file

Let's assume that you can't edit the CiviCRM files or database - or only will do so as a last resort :)

These are existing memberships, so you should be able to export the memberships info with the actual start date, add the start_date to your CSV file and import with the start date.

I'm surprised membership start date is required....I'll ask that question on stack exchange :)
