How to change EPS inbox folder for JAVA upgrade using SUM

I want to change the standard EPS/in directory in the middle of my upgrade for Java system. How do we change?

Due to space constraint on E-drive, I have moved the data for E:\usr\sap\trans\EPS\in to another share location \\crpsap\trans\EPS\in. SUM with ABAP recognized using DIR_EPS_ROOT Instance parameter, but SUM with JAVA doesn't seem to recognize. I have added this parameter and also added parameter "/jspm/inbox=\\CRMhost\trans\EPS\in" in "E:\SUM.JAVA\sdt\param\jspm_config.txt" and "E:\SUM.JAVA\new\sdt\param\jspm_config.txt" files. Still I see the same error for SUM tool. Any other thing missing to change EPS/in for JAVA?
