What is projection parameters for converting GCS_WGS_1984 to GCS_Everest_1830

I am facing problem of data shift between two different coordinates GCS_WGS_1984 and GCS_Everest_1830. Can anyone please suggest to convert GCS_WGS_1984 to GCS_Everest_1830 or vice-versa and what parameters need to use to match the data in same position.

thanks in advance
