I think Mukul has provided great cloud code for this issue

here it is

Parse.Cloud.beforeSave(Parse.Installation, function(request, response) {
Parse.Cloud.useMasterKey();
var query = new Parse.Query(Parse.Installation);
query.equalTo("owner", request.user);
query.equalTo("uniqueID", request.object.get("uniqueID"));
query.first().then(function(duplicate) {
    if (typeof duplicate === "undefined") {
        console.log("Duplicate does not exist,New installation");
        response.success();
    } else {
        console.log("Duplicate exist..Trying to delete " + duplicate.id);
        duplicate.destroy().then(function(duplicate) {
            console.log("Successfully deleted duplicate");
            response.success();
        }, function() {
            console.log(error.code + " " + error.message);
            response.success();
        });

    }
}, function(error) {
    console.warn(error.code + error.message);
    response.success();
});
});

Note that owner is the username or the primary key that you think u can use.
