I have two meteor apps built with different versions of meteor.
If they use different versions of mongo, will they both work if deployed to the same server?
In other words, does each deployed app run its own copy & version of mongo?

For ease of use locally, meteor has it’s version of MongoDB but when deployed, you can use any of the maintained versions of meteor and MongoDB, and they will probably work just fine (unless you are using some crazy MongoDB feature)
You can even connect to the same MongoDB multiple meteor apps, and those apps can be in different meteor versions(maybe some apps will not have a feature because of the MongoDB driver’s differences, but it should work fine for common cases)
so all deployed apps onto a single server use the same mongo instance, or do they / must they use their own instances by default?
