This topic addresses common questions about the behavior of ArcGIS Server 12.0 when used with ArcGIS software components from earlier release versions.
Can I connect to ArcGIS Server from ArcGIS Pro?
Yes, you can add a user connection from any version of ArcGIS Pro to any currently supported version of ArcGIS Server.
ArcGIS Pro uses a different version schedule than ArcGIS Enterprise; it's recommended that you keep ArcGIS Pro at its newest version.
Can I configure a different version of ArcGIS Web Adaptor with ArcGIS Server?
No. To configure ArcGIS Web Adaptor with ArcGIS Server, both software components must be of the same version.
To upgrade ArcGIS Web Adaptor, you must uninstall the instance at the previous version, and install an instance at the new version. By specifying the same name as your previous Web Adaptor, you can guarantee your Web Adaptor URLs will remain identical after upgrading.
Can I reuse a cached map I created in an earlier version of ArcGIS Server?
Yes. Map caches from previous versions are immediately available after you upgrade.
Ensure your caches are using the compact cache storage format, which provides optimal performance when consuming cached map and image services.
Can I connect to geodatabases of an earlier version from ArcGIS Server?
Yes. See Client and geodatabase compatibility for a list of compatible versions.
Can I publish services to ArcGIS Server that contain data from geodatabases of an earlier version?
In most cases, the geodatabase version does not have to match the version of ArcGIS Server. For specific information on which geodatabase versions are supported with ArcGIS Server 12.0, see Client and geodatabase compatibility.
Do I need to upgrade my geodatabase to use it as the ArcGIS Server managed database?
Earlier geodatabase versions can be used as the managed database for an ArcGIS Server site. For specific information on which geodatabase versions are supported with ArcGIS Server 12.0, see Client and geodatabase compatibility.
Managed databases are enterprise geodatabases registered with ArcGIS Server sites to facilitate feature access in scenarios when you need data to be stored in a different location than the source location. To learn more, see Copy data when publishing to ArcGIS Server.
Note:
Feature services and WFS services published from ArcGIS Pro to a stand-alone server must reference data in an enterprise geodatabase and cannot use a managed database.
