ArcGIS Enterprise upgrade

[BarryG]

We are planning to soon upgrade from ArcGIS Enterprie 10.8.1 to 11.1.  This will be our first ArcGIS Enterprise upgrade to complete since initial installation. 

My question is with upgrading ArcGIS Enterprise, will we be required to configure the software applications again (i.e., add the Certificate, configuring the identity store, etc.), or shall the upgrade recognize and keep these settings?

Hi @BarryG 

No, the Certificate and the Identity Store (plus other ArcGIS Enterprise security settings) will stay in place after your upgrade.

Remember there are also other changes to consider in upgrading between these versions, for example, the removal of the ArcMAP Based runtime.

Thank you Chris. Yes, I am familiar with the changes to the ArcGIS Enterprise 11 developments.  We are good, as far as that goes, as we haven't developed much in Enterprise at this point, but mostly published map services (via ArcGIS Pro only).

We will soon be upgrading from Enterprise 10.9.1 to 11.0 and we want to know: will our published web maps be unavailable during the upgrade? what will our public users experience while we are upgrading Enterprise?

Although there are MANY changes and requirements, updating ssl certificates and re-configuring user / identity stores is not among them.  BUT, this how-to document

https://support.esri.com/en-us/knowledge-base/how-to-upgrade-to-arcgis-enterprise-11-x-000029452

recommends not directly upgrading directly to 11.1 from releases more than 2 versions behind, and you are 3 versions behind.  If you can do an interim upgrade to 10,9.1 first I would do so . . .

Upgrading from 10.8.1 to 11.1 is absolutely supported - "If these workflows do not impact your organization, you can upgrade directly from ArcGIS Enterprise 10.7.1 or later to 11.1."

https://enterprise.arcgis.com/en/get-started/latest/windows/considerations-for-upgrades-to-11-0-and-...

Whilst running the post-installer for ArcGIS Server 11.1 - each service which is still using the ArcMap runtime will be upgraded (or attempted). A very useful report of the upgraded services is available post-upgrade. Read more here - https://enterprise.arcgis.com/en/server/latest/publish-services/windows/check-services-with-arcmapse...

Some configurations are lost/not-supported between versions e.g. If you have WebGISDR setup on a schedule, I would recommend reviewing the properties file to incorporate any changes required. 

Most configurations are maintained as mentioned by Chris. Once you've completed your upgrade, I'd recommend running the portalScan / serverScan python utilities to ensure your deployment is following best practices.

I'm in the same boat, going from 10.8.1 to 11.1 Also my first upgrade. I've taken care of the runtime switch, but I have a question related to the required disk space portion of the upgrade documentation

From step 3 of https://support.esri.com/en-us/knowledge-base/how-to-upgrade-to-arcgis-enterprise-11-x-000029452

"Check the system requirements for the machine(s) that hosts the ArcGIS Enterprise products and ensure it meets the minimum requirements. From this, a list of the recommendations can be made like increasing the CPU, disk space, etc., before starting the upgrade process. See: ArcGIS Enterprise 11.0 system requirements

Keep in mind that the amount of free space available on disk should be at least 2.5 times the amount of space in the directories. If not, allocate at least 2.5 times more space on disk. The upgrade must have this free space to successfully back up and upgrade your portal's content, site information, and security settings. "

If I read that correctly, the actual disk drive containing a directories folder has to have 2.5 times the filled space in the directories folder itself? So as an example, I have my ArcGIS Server directories on our D drive. There is 43 GB of files in the directories folder. That would mean that my D drive has to have 107 GB of free space?

[A_Wyn_Jones]

Correct @ZachBodenner - the reason is that backups and duplicates of your current deployment are made during the upgrade. 

There will be redundant files post-upgrade which are safe to delete - although I would recommend, where possible, to clean these up via the tools provided e.g. ArcGIS Datastore cleanup utility

https://enterprise.arcgis.com/en/data-store/latest/install/windows/data-store-utility-reference.htm#...

Please keep in mind that if you have your directories on various disks (I.e. arcgisportal on E:\, arcgisdatastore on D:\ etc), this applies to each content directory. 

Obviously, please validate that your upgrade was a success before deleting these files. As always, lots of snapshots with the ArcGIS services stopped.

[ZachBodenner]

Thanks, that's helpful!

By "snapshots" do you mean VM snapshots, or something done with an ArcGIS utility, or both, or something else entirely?
