Change ArcGIS Server Hostname

[dedimi]

Hi All,

I have a plan to change some VMs hostname that has ArcGIS Server installed on it. The VM OS is RHEL 7.9 and the ArcGIS Server version is 10.7.1.

I found 2 articles regarding this and I think their content have opposite meaning:

•  https://support.esri.com/en/technical-article/000010811  -> The hostname of server cannot be changed once the ArcGIS server software is installed.

• https://enterprise.arcgis.com/en/server/10.7/administer/linux/common-problems-and-solutions.htm#anch... -> Can I safely rename a GIS server machine in my ArcGIS Server site?
  Yes. ArcGIS Server will automatically detect a machine name change and reconfigure your site to use the new name.

At the first article for Linux OS the server hostname can not be changed while at the second article it can be changed.

Appreciate if anyone can give some advices and maybe can share the experience in this regard

how about stand up a new vm with the name you want

install ArcGIS Server software on it

join it to your existing ArcGIS Server "site"

keep both or ditch the old one

Actually my plan is to clone the existing one and then I'll upgrade the ArcGIS version to 10.9.1, once it's settled then I'll decommission the old one. Because I want to avoid data migrating process and while do the upgrading, user is still able to utilize ArcGIS in the old one however in read-only mode.

"Yes. ArcGIS Server will automatically detect a machine name change"

They left out "It's magic!"

Are you using it with Portal? If you are only using Server it's probably fine to trust them. If it's a VM, snapshot it first and roll back if the magical thing does not happen.

Yes, actually it is in ArcGIS Enterprise, so working with Portal. 

I don't want to take the risk with the magical thing, that's why if anyone has experience of it would appreciate to share.

Were you able to get all the Portal part running after your server name change? ....  I got this link from Customer Care after...   https://enterprise.arcgis.com/en/portal/latest/administer/windows/common-problems-and-solutions.htm#...
