Multi-Org support in Marketing Cloud Connect allows a single Marketing Cloud account (with its multiple Business Units) to connect to more than one Salesforce org — precisely the acquisition scenario described, where each acquired company retains its own Sales Cloud instance. The critical, documented consideration a consultant must flag before recommending this upgrade is that it is a one-way, irreversible architectural change: once an account is upgraded to support Multi-Org connections, it cannot be reverted back to a single-org configuration. This is a significant governance decision that warrants careful upfront planning around Business Unit-to-org mapping, since undoing it later is not possible. Option A is factually incorrect — existing single-org accounts can be upgraded to Multi-Org; that is the entire point of the upgrade path. Option B is also inaccurate; Multi-Org actually partitions Synchronized/Salesforce Data Extensions per connected org and Business Unit rather than sharing them freely across the whole account. Option D is unrelated and untrue — subscription centers and profile configuration still need to be built out per Business Unit regardless of Multi-Org status. The irreversibility in option C is the single most important decision-point consultants must surface. Reference: Marketing Cloud Connect Multi-Org.
