netlist conversion from Xilinx to altera compatible

--- Quote Start ---

I am working on porting netlists from Xilinx ISE to Altera Quartus III. Can anyone help me in fixing this issue? Is there a converter or any software to convert Xilinx compatible netlist to Altera compatible one??

What do you mean by a netlist?

What you should really have is the original source code in Verilog or VHDL format. You would then change the Xilinx IP for equivalent Altera IP and then resynthesize.
