Campaign Classic v7 vs Campaign v8?

“v8 is the evolution of Classic v7: it keeps most of its features, but runs only as a Managed Cloud Service, sends everything through mid-sourcing and, in Enterprise (FFDA), executes campaigns on Snowflake. It doesn't support on-premise or hybrid deployments, LDAP or username/password sign-in. Automated migration from v7 doesn't exist yet, and v7 has core support until December 31, 2030.”
