Thanks for your query. Unfortunately, our systems don't yet integrate with the Cisco partner tool, so you will need to keep a record of Meraki training attendance separately. You should be able to save your CMNA or CMNO certificates locally. Currently, these don't have an expiration date. If anything changes we'll be sure to communicate this to our partner community.
Our intention is to have this certification integrate with the Cisco Certification Tracking System at launch and be trackable just like any other Cisco specialist or career certifications. Be on the lookout on the Community for more information in the coming months as these processes get finalized.
