Hi,

Please find below the script to convert a map as per your requirement :
  
Map<Id,String> existingMap = new Map<Id,String>();
//Assuming that your existingMap is already populated with values

Map<String,Id> updatedMap = new Map<String,Id>();

for(Id KeyValue : existingMap.keySet()){
	updatedMap.put(existingMap.get(keyValue),keyValue);
}

//Now you have your new Map updatedMap with your required values.

Let me know if you need more help.

Regards,
Abhishek
