Answer 1

You can run multiple mongoDB version on the same host as long as these version are not in the same Replica Set as a general rule (which judging by your question will not be a problem).

Deploy 2 installation paths.

Start the application using:

mongod --port 12345

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

Default port is 27017 if port not 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 /b c:\mongo1\bin\mongod --dbpath "c:\mongo1\data" --port 27017

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

When connecting using MONGO.exe be sure to specify port to connect to correct instance.
