Best Practice to Migration 10.5.1 Server to a new Machine

Lake_Worth_BeachAdmin — Fri, 06 Apr 2018 13:07:40 GMT

I have ArcGIS Server 10.5.1 installed on a machine1, I want to migrate this installation to machine2 and then remove the original install on machine1.

what is the recommended procedure to accomplish this?

All Services are hosted on a shared network drive not on the local server machine.

We plan on writing a blog to discuss some approaches to this. Since you have your directories on a share already, I would just install the software on machine 2, join it to machine 1, and then remove machine 1 from the site so you're left with machine 2.

Would there be any issues with this approach if machine 1 is Windows Server 2012 R2 and machine 2 is Windows Server 2016?

No, the operating system doesn't matter, it will work between OS versions.

Any update on a the blog post for this procedure?

Does it matter if the starting (single) ArcGIS GIS server is federated with Portal?

Is the ability to do this included with 10.4.1, 10.5, 10.5.1, 10.6, 10.6.1?

Let us know if you have any comments or questions.

Yes, it definitely does matter, as there are a few places where the machine URL is baked into config-files/settings. If you're moving Server, you'll want to update the admin URL for the federated Server in the Sharing API. I just took a look at the blog and I think we missed that step, so I'll get that reviewed and updated.

It works with any version of ArcGIS Enterprise.

Thank you Jonathan,

That Scott MacDonald blog link included a reference at the bottom of the page to this blog post about the deprecated multi-cluster ArcGIS Server option which is what was bugging me about this issue.

This blog post clarifies we can still use the cluster option to step into new machines.

Which blog makes you think that multiple clusters in a single site is still OK? We'd like to look at that and make sure we're being clear that multiple clusters is not the way to go. You can migrate machines in and out of a site even if the site only has one cluster, for example the default cluster.

Hey Jonathan,

the blog does not mention anything about the SSL/TLS certs in IIS Webserver in regards to the migration.

will the same cert still work or will modifications be needed to adjust for the new machine name?

It was my reading of the 10.5.1 deprecation notice.

10.5.1

Support for cluster functionality
Esri is announcing the deprecation of the cluster functionality within the ArcGIS Server component
of ArcGIS Enterprise. Instead we recommend creating separate ArcGIS Server sites where multiple
clusters would have been used previously. While we are not announcing a specific future release
where cluster functionality will be removed, the use of multiple clusters for new deployment is
strongly discouraged and existing deployments are advised to migrate away from use of clusters as
part of ongoing maintenance and upgrades.
Note: this does not affect the ability to create multi-machine sites.
ArcGIS Server sites with multiple machines continue to be fully supported.

vs. 10.6 deprecation notice

Support for Multiple Clusters with ArcGIS Server
ArcGIS Enterprise 10.6.x will be the last major release series to support multiple clusters with ArcGIS
Server. This was previously deprecated at ArcGIS Enterprise 10.5.1 and we are n
ow announcing the
official removal of that feature from the product in the next major release. Users with multiple
clusters are strongly encouraged to migrate to a different deployment pattern to avoid disruption at
later releases.

Changing the front-facing URLs of an ArcGIS Enterprise deployment isn't supported, so the certificate should still be valid as it's created with a CN or SAN that includes the FQDN of the front-facing URL. If you needed to migrate the machine that is creating the front-end, (web adaptor, for example), then you can still use your existing certificate but you'll need to work with your IT staff to update the hostname of the new machine to match the old machine name.

machine 1 is Windows Server 2012 R2, however machine 2 is windows server 2016.... is this not compatible?

Yes, there are no problems if the OS versions are different.
