There is no reason to let your ISO 9001 Certification go; you can use the two management systems together effectively to manage both quality and food safety for your products or services. Many companies have both certifications, and your certification body should be able to provide you with an integrated audit. (Auditing both systems during the surveillance audits)
No it is not necessary to have ISO 9001 to achieve ISO 22000 Certification. They are separate standards, ISO 9001 is for a quality management system, ISO 22000 is a food safety management system. The 2 systems can be integrated if a company chooses to pursue them both.
