We have two websites in Magento 1.9. We are planning to migrate them to Magento 2.x after 4 months. These websites are compliant with SAQ-A and SAQ-A-EP respectively. What will happen after 30th June when Magento stops supporting Magento 1 websites? What do I need to do to stay SAQ-A and SAQ-A-EP compliant after 30th June?
