We are in the process of upgrading our ArcGIS Enterprise deployment from 11.2 to 11.3. So far, we have successfully upgraded Portal for ArcGIS, ArcGIS Server and ArcGIS Web Adaptor to 11.3. However, the upgrade of ArcGIS Data Store was not successful. It proceeded up to the point at which it stated that it was configuring the ArcGIS Data Store service then it hung at that point for a few hours. I cancelled the install after it became unresponsive. After running the ArcGIS Data Store installer again, it continues to hang at various points such as after specifying the ArcGIS Data Store account or when validating the install. I should also mention that I tried uninstalling ArcGIS Data Store to install it afresh but it also hung during the uninstall and I cancelled this too. The 11.3 installer continues to detect the previous version for upgrade even though it's no longer in the Windows list of installed programs.
We'd appreciate it if someone could assist us in resolving this problem.
