Layer symbology - adjust to new attribute values

I have got many layers each one with extensive symbology. Now I need to change the data source for these layers. The new data sources have different table names (no problem), different field names (no problem)  and different values. Now I struggle with the values - I thought I could just edit the values and replace them (such as "1" with "510"). But I can't figure out how. Is that possible (ArcMap 10.3)? I don't want to create lookup tables as suggested somewhere else. If I cant change values used in layer symbology in ArcMap - could it be done using ArcPy (yes / no)?


Thanks, Rob
