Rigify character from blender 2.76,

Hi , Are there any known issues with trying to use a character rigged with rigify from an old version of blender ( I think it was 2.76 but I’m not sure) with the latest blender? I’m not seeing the IK FK sliders and options. Will I have to re-rig in a newer version blender and rigify?

Thanks for reading,

Hi, you have to append the rig_ui.py from previous files which you will find under text . Then you have to run the script from new file
