Hardly legacy?
But Fuller’s brewery Infor system is hardly a legacy application.
For Asahi, it is absolutely a legacy system. It is not a core part of their systems, it is a system brought on board as part of the legacy of Fuller's operations, therefore it totally fulfils the definition of a legacy system.
In general, IT, terms, it might not be an ancient, legacy system , but in the Asahi corporate world, it is definitely classed as a legacy system.

The second definition is pertinent to the Asahi case, this is something handed down from the predecessor (previous owners, Fuller) to Asahi as part of their takeover.
