As ESMA has opened new portal, you need to create account on the portal for further certificates – Login – SSO (moiat.gov.ae).
The old ESMA account shall be invalid after specific date, but the date is not yet decided by ESMA. Certificates which were issued to the old account shall be valid until the end of their validity date, and you need to apply for the new certificate on the new portal after the certificates are expired.
The old certificates will not be found in the new account, but you don’t need to worry about renewal. In any renew process, we are applying for new certificates, so there is no problem even though the certificate does not appear in the new account. The new application will be submitted in the new portal, and ESMA will consider it as renewal since your product has already been certified.
