Migration: Plus → AC, AC → Plus, timeline + cost?

Either direction requires a scoped transition design. Inventory current modules and apps, company pricing, account access, integrations, useful URLs and historical records. Rehearse representative data and a difficult company order on the proposed product. Adobe SaaS requires a different extension migration from Adobe PaaS, so identify that choice early. Set cost and schedule from the demonstrated gaps, data volumes and acceptance criteria; a fixed enterprise migration duration is not established by the platform names.
