Unfortunately, it is not possible to convert certificate types from the V4 standard (ex-ante and ex-post) to certificate types from the V5 standard (fPVCs, rPVCs, vPVCs). The V5 Standard encompasses many processes (monitoring, conversion, vintages, non-achievement reserve, risk buffer contribution) that differ from the V4 Standardand. Therefore, ex-ante and ex-post certificates do not align with the processes under the V5 Standard. In addition to this, projects migrate at verifications and verifications serve to verify that the "old" certificates, i.e. those generated prior to the verification event, are compliant with the V4 the PDD and annual reports being applied and submitted during that time period. Only after the verification and migration will the project generate certificates that are aligned with the V5 standard.
