Can I have two separate license managers running on a single WIndows server?

We are planning to migrate our ArcGIS Servers to our internal network, from the DMZ. In doing so, we'll need to migrate the License Manager, which resides on its own (DMZ) server. Can I move and run this License Manager, concurrently, on the internal server which houses the internal License Manager?

You can set up multiple license managers and license server processes with different port numbers and everything, but if you can it makes a lot more sense to combine your license files and run them under one server.

Please provide multiple License Managers installation process on same license server. When we tried to launch the installation, a "Program Maintenance" window launched with "Repair" and "Remove" radio buttons. Trying with the same installer which we used to install License Manager before.

Please suggest how to proceed.

Rey,

You cannot install multiple ArcGIS License Manager on the same machine.  The workflow is to deauthorize licenses from you old server and authorize them on the new server.  If you have existing licenses on the new server, the authorization will add to the existing licenses.  

Is there any particular reason why you would prefer to run multiple license manager on the same server? 

[PrasannaS]

We need to install ArcGIS and ArcFM components and these components have to be connected to the same license server. Licenses for these two components are different. We came to know that, we can install multiple license mangers running on different ports on same license server.

[AmnoyAm]

Yes, that is correct.  You can install license managers from different vendors on the same machine.  The key is to run the them on separate ports.  Thanks for the update, Prasanna.

can we install two different versions of the license manager software on two different different servers temporarily without impacting the licensing

[DennisSmith]

The bigger question is why the different versions? The ArcGIS License Server Administrator licenses are fully backward compatible. You can install different versions on different machines in the network but this falls back into the why different versions?
