Easy way to connect dev app with production app?

Hey guys,
I’m trying to connect my dev app with my productional version. Just for example, on my productional version I’ve some posts which I want to subscribe to. I’ve just read about the way using DDP.connect() on every collection, f.e.:

var conn = DDP.connect(“http://app.mysite.com”);
Posts = new Meteor.Collection(“posts”,conn);

But when using this, I’ll get the following error:

207-23:18:32.556(1)? Exception from sub posts id ijKrc5E5cmmrDHryN Error: must use ordered observe (ie, 'addedBefore' instead of 'added') with skip or limit I20151207-23:18:32.556(1)? at [object Object]._.extend.observeChanges (packages/minimongo/minimongo.js:325:1) I20151207-23:18:32.557(1)? at Function.LocalCollection._observeFromObserveChanges (packages/minimongo/observe.js:177:1) I20151207-23:18:32.557(1)? at [object Object]._.extend.observe (packages/minimongo/minimongo.js:305:1) I20151207-23:18:32.557(1)? at Publication.publish (packages/reywood_publish-composite/packages/reywood_publish-composite.js:65:1) I20151207-23:18:32.557(1)? at packages/reywood_publish-composite/packages/reywood_publish-composite.js:413:1 I20151207-23:18:32.557(1)? at Array.forEach (packages/es5-shim/.npm/package/node_modules/es5-shim/es5-shim.js:417:1) I20151207-23:18:32.557(1)? at Function._.each._.forEach (packages/underscore/packages/underscore.js:134:1) I20151207-23:18:32.557(1)? at [object Object].

Is there an “easy way” to switch the data connection to the productional server?
