Is it possible to run 2 different versions of MATLAB Job Scheduler on 1 machine simultaneously?

Is it possible to run 2 different versions of MATLAB Job Scheduler on 1 machine simultaneously? I'm attempting to do so and am getting this error:

ERROR: wrapper  | CreateService failed - The specified service already exists. (0x431)

You cannot run 2 MJS (MATLAB Job Scheduler) services of different versions on the same machine.

For R2016a and newer, a single instance of MATLAB Job Scheduler can support multiple releases of MATLAB Parallel Server, as seen in the link below.

Run Multiple MATLAB Parallel Server Versions

For older releases, it is possible to have a third-party scheduler serve multiple installations of MATLAB Parallel Server. The integration of MATLAB with the third-party scheduler will ensure that the version of MATLAB started on the cluster will be the same version as that used to submit the job.
