Client export/import of PRD to stand alone clone & test system

We need to refresh our Clone & Test system with a copy of PRD. Its a stand alone system used by SAP to connect and analyse error's as our systems cannot allow connections from outside.

Since our last batch of patches were imported we have encountered some problems and need the C&T server refreshed with data in order to replicate the problem for SAP

Any help/suggestions would be greatly appreciated as we need this done urgently
