    Specified by:
    
    install in interface DataHub
    
    Parameters:

    Note that this differs from how "mlUpdateIndexes" works in ml-gradle. This is not stripping out any "non-index" properties from each payload - it's just updating every database. This does however disable forest creation which speeds up the process so that the only calls made are to update the databases.

```
public void setServerVersion(java.lang.String serverVersion)
```
    Description copied from interface: DataHub
    
    Sets the server version holder on the datahub object - currently unused
    
    Specified by:
    
    setServerVersion in interface DataHub

                                      throws java.io.IOException
```
    The expectation is that a user has upgraded build.gradle to use a newer version of DHF but has not yet updated mlDHFVersion in gradle.properties. Thus, the value of mlDHFVersion is expected to be passed in here so that the backup path of hub-internal-config has the current version of DHF in its name.
    
    Parameters:
    
    hubProject -
    
    currentDhfVersion -
    
    Throws:
