What are the ways to migrate built-In users from ArcGIS Enterprise portal 10.9.1 to 11.5?

codethemap — Wed, 03 Jun 2026 17:16:07 GMT

We are planning to migrate from ArcGIS Enterprise 10.9.1 to 11.5.

So What are the ways to migrate built-In users from ArcGIS Enterprise portal 10.9.1 to 11.5?

Can we do it using:
1. Python Script? if yes what are dependencies to create a script?
2. Can we export built-in users from 10.9.1 and import the same in 11.5?
3. Any other option if available?

If you are doing an in-place upgrade from ArcGIS Enterprise 10.9.1 to 11.5, built-in Portal users migrate automatically as part of the Portal upgrade. No separate user migration is normally required.

Hey @codethemap

Agreed with Jon, the users in my case have always automatically migrated, I performed a 11.5 upgrade from your version, but with intermediary upgrades. Each upgrade it has automatically moved the built-in users without any interaction from my side.

Have any problems came up in the past?

We are setting up ArcGIS Enterprise 11.5 on totally new infrastructure. So No In place upgrade.

Any reasons why you are not trying to migrate your existing enterprise from the old infrastructure to the new infrastructure? I think this is what webgisdr can be used for. I would research webgisdr from ESRI documentation supplemented by Google searches and ChatGPT. I think you would get your existing enterprise 10.9.1 on new infrastructure and then perform the upgrade from 10.9.1 to 11.5 on the new infrastructure.

Hey @codethemap

As MikeVolz mentioned, WebGISDR would be the best to use in this situation. You would install 10.9.1 on the new servers, and then deploy the WebGISDR to pull the environment over. Once done, you'd then perform in-place upgrades to finalize your upgrade.

Otherwise, you can perform a CSV export of the users using the ArcGIS API for Python from your 10.9.1 instance, and then transfer to the new infrastructure if you already have that installed.

We are using Windows server 2025 and it is not supported to 10.9.1.

Can you try to perform an inplace upgrade of enterprise from 10.9.1 to 11.5 on existing servers at whatever version of Windows Server that they are at and once that is complete perform an upgrade to Windows Server 2025 on those servers making up your enterprise GIS environment? You would only be temporarily using an older Windows Server version just to upgrade your existing GIS software.
