Last 2 months I’ve been working on renewing my Office 365 and Azure certifications. 4 years ago I already passed the “old” exams: 533, 534, 345, 346 and 347. This saved me a few exams. I was able to upgrade to Azure Administrator and Messaging administrator by passing the upgrade exams. For the Azure Solutions Architect I had to take the AZ-300 and AZ-301 exam as an upgrade exam was only valid for those who have passed the follow up exam of 534: 535.
So here is the final result, I will be looking into the Azure Security exam in the future (AZ-500) as well as the Microsoft 365 Certified Enterprise Administrator Expert (MS100 & MS101)
