Run Different Version of ARAS on same server?

Hi everybody

Does anyone know if it's possible to have 2 different Aras version installed (ie 11sp12 and 12.0) on the same machine for test purpose?

I assume il wil have separate databases and vaults.

Best regards

  • Hi CC,

    This is most definitely possible. There are a few important things to note when installing your second instance. You'll have to ensure that the second instance has unique identifiers. This means it needs it's own file path, database name, conversion server path, and web alias. Each install will create a new database and each instance of innovator will have it's own vault. Going through the installation documentation in the 12 CD image should help you figure out how to set each one of these individually. It should be pretty straightforward, but let me know if you have any issues!


  • Hi

    I made sure the second instance has unique identifiers but when trying to connect I get an error

    "Error: Cannot access OAuth Server due to 500 (Internal Server Error)"

    I checked the xml config files and don't see any mismatch with server names,etc.

    Any hints?



  • HI CC,

    Can you verify that the version of .NET Core installed on the machine matches the version which is a prerequisite within the installation documentation?

  • Hi

    Thank you for your help.

    I did not read properly the prerequisite (sorry), performed install  of the good components.

    But it's still not working, i now get en error:

    "Error: Cannot access OAuth Server due to 502 (Bad Gateway)"

    Best regards


  • finally solved by using the right core.

    thank you again


  • Same error, but only trying to install v12 in testing env.  .Net Framework, Core, Runtime, Hosting versions, all confirmed - yet, still 502 Bad Gateway.  Any thoughts?

    Thank you,


  • Don't install the latest version from Microsoft, install the exact version mentioned in the installation guide (.Net core 2.1.8)

  • Hi Sebastian,

    We want to test the version 12, so firstly in parallel to the 11SP12. We stopped installation since we had a doubt.

    Installation is done in a dedicated directory, the conversion server path is also specific, based on dedicated web alias, but what about the "service agent" (the wizard is in French, so the translation could differ...)?

    Defaut value is http://localhost/InnovatorServer/Server/InnovatorServer.aspx it sounds strange since this is the same for the both Innovator versions...

    Any suggestion?

    Thank you,


  • Hi Vincent,

    From my experience I believe yuou should set the value to http://localhost/{webalias}/server.....

    I'm unsure why the default doesn't automatically update when the web alias is entered, but you'll want to make sure to set it properly.


  • Hi Sebastian,

    That corresponds to my doubt since the path is asked before the definition of the {webalias}.

    I asked my 'administrator' to do that... I'd confirm it as soon as installed.
