We did this when upgrading from 0.9x to FlumeNG 1.3-SNAPSHOT. Used different ports and different logging/data directories. Worked great.

Subject: Running multiple flume versions on the same box
This is primarily to try and address a flume upgrade scenario in the case of any incompatible changes in future. I tried this with multiple processes of the same version, and it appeared to work. Are there any concerns on running multiple versions of flume on the same box (each with different agent configurations where there is no overlap of ports) ?
