My company already has ISO 9001:2000, will I need to be re-assessed to the new standard?

It is expected that conformity to the new ISO 9001:2015 standard will be evaluated by certification bodies during regular surveillance visits and that full reassessment will only take place once current certificates expire. However, it should be noted that ISO and the IAF (International Accreditation Forum) have agreed that all certificates to ISO 9001 should be upgraded to ISO 9001:2015 within 2 years of publication of the amended standard.
