  The GridCellClassParams type is not exported anymore. Replace it with GridCellParams.

  -import { GridCellClassParams} from '@material-ui/data-grid';
  +import { GridCellParams } from '@material-ui/data-grid';
  
  -cellClassName: (params: GridCellClassParams) =>
  +cellClassName: (params: GridCellParams) =>

  The cellClassRules in GridColDef was removed because it's redundant. The same functionality can be obtained using cellClassName and the clsx utility:

  +import clsx from 'clsx';
  
   {
     field: 'age',
     width: 150,
  -  cellClassRules: {
  -    negative: params => params.value < 0,
  -    positive: params => params.value > 0,
  -  },
  +  cellClassName: params => clsx({
  +    negative: params.value < 0,
  +    positive: params.value > 0,
  +  }),
   }

Can we move those hardcoded class names into cssClassesConstants.ts and build them using the GRID_CSS_CLASS_PREFIX? That way if we change it in the future it will be easier to handle the change.

Even better, we can reproduce the classes approach of the core component (dataGridClasses.ts + generateUtilityClasses). I have added the item to #408.
