Default [Q] Move some folders from /data/data/ to /data/sdext2/data/?

I have LINE PLAY which installs its data onto the internal memory. The problem is, I have a small internal memory and it's almost full. Since I'm using Link2SD, I have a second partition on my memory card which is formatted as Ext3. I want to know how I can move LINE PLAY's data (which is located on /data/data/ to /data/sdext2/data/ I already tried making a symbolic link but LINE PLAY just crashes when I do that.
