Migrate federated to managed using PHS + PTA + Seamless SSO

Hi there, Do you have a Federated environment where I can demonstrate migrating authentication from Federation to PTA / PHS + Seamless SSO? If you're looking for understanding user experience, we can just enable staged rollout and demonstrate the same. If you'd like to perform a cutover migration and then see the user experience, that's possible too. I'd like to understand what Federation servers are you currently using, is it Microsoft ADFS or other federation servers like Ping / Okta? Please ping me and we can discuss further. I've done numerous Azure AD projects and assisted enterprise customers with Azure AD integration and migration. I've been working on Windows and Azure for the past 8 + years.
