We have a UIM installation 20.4 on Windows Server 2016 and MS SQL Server 2016. We have a primary hub and 15 secondary hubs.

I need to make UIM highly available and I will use the approach of Windows cluster. So we will create a cluster and join the existing UIM on it.

I need to know what are the best practices for this. What to do on the existing primary hub IP? Should it be the VIP of the cluster ? .. what about the installation directory ? and what about the installation of the other primary hub node?

I checked this document Installation procedure for UIM on Microsoft Windows cluster environment ( but it talks about new installations not existing.


Release : DX UIM 20.4*/23.4*

Component : UIM - INSTALL


- Guidance


Yes, you will use a virtual IP address for the cluster.

Install to a location on the shared drive, such as S:\Nimsoft. Do not install to the C:\Program Files directory...

Yes, you do also install DX UIM on a second node but read through the documented process.

Please do review this entire techdoc.

Installing an Active/Passive Microsoft Cluster

As with most product installations, retro-fitting into a cluster is likely to be difficult, as several decisions are often made during install, for example configuration settings and location on disk.

Creating a new installation in the cluster and migrating the existing hubs and robots is the preferred and much easier option.

Feel free to also post a message to the UIM Community to see if any other customers have had experience adding UIM Into an existing Microsoft cluster.

If you need help with this configuration effort with an existing cluster, you can contact your Account Rep to discuss it or contact one of our Partners for assistance.
