You can run multiple versions of mongoDB on the same host, as long as that version is not part of the same replica set as a general rule of thumb (which won't be a problem from your question).

Expand the 2 installation paths.

Run the application using:

mongod --port 12345

(where 12345 is the port you specified) To run exe on a different port.

The default port is 27017 if no port is specified in the command.

See http://docs.mongodb.org/manual/tutorial/manage-mongodb-processes/

Example:

Deploy:

C: \ mongo1 \ Bin \ mongod.exe

C: \ mongo1 \ data \

C: \ mongo2 \ Bin \ mongod.exe

C: \ mongo2 \ data \

Execute:

start / bc: \ mongo1 \ bin \ mongod --dbpath "c: \ mongo1 \ data" --port 27017

start / bc: \ mongo2 \ bin \ mongod --dbpath "c: \ mongo2 \ data" --port 27050

When connecting using MONGO.exe, be sure to specify the port to connect to the corresponding instance.
