WAS Java SID change/System copy

Need help !

We are trying to rfresh QA from PRD using disk copies from production (using EMC technology). We are running 4.7/640 (ABAP+Java)/Sun/Oracle/.

ABAP stack and Database comesup clean with new SID, not Java stack. Has any one done a system copy on Java stack (with SID change?), if some can help us, that will be geatly appreciated.

(We know Homogeneous system copy works, but we cannot afford production downtime).
