To configure the secondary server to be an additional web server and Solr Cloud node, follow these steps. 

Note: in order to add Solr Cloud shards to the secondary server, the current index needs to be deleted, requiring a re-index of all data.

1. Start by opening Command Prompts in administrator mode on both machines and stop the index service on all machines.
2. Primary: Add new inbound firewall rule. Execute following line in command prompt: 
   netsh advfirewall firewall add rule name="ViaWorks Zookeeper" protocol=TCP localport=9983 action=allow dir=IN profile=domain

3. Primary: Remove all data EXCEPT "configsets" from ProgramData\VirtualWorks\ViaWorks\Solr
   
4. Primary: Remove all data from ProgramData\VirtualWorks\ViaWorks\ZooKeeper
   
5. Secondary: In Program Files\VirtualWorks\ViaWorks\SOLR\bin\Solr.in.cmd replace line "REM set ZK_HOST=" with "set ZK_HOST=<<PrimaryIP>>:9983". On Locator upgrades this will be loaded from the Secondary's DataAccess.config
   
6. Secondary: Add new inbound firewall rule. Execute following line in command prompt: 
   netsh advfirewall firewall add rule name="ViaWorks index admin dashboard" protocol=TCP localport=8983 remoteip=<<PrimaryIP>> action=allow dir=IN profile=domain

7. Secondary: Remove all data from ProgramData\VirtualWorks\ViaWorks\Solr. The config sets will now be loaded from ZooKeeper/Primary
   
8. Secondary: Remove all data from ProgramData\VirtualWorks\ViaWorks\ZooKeeper
   
9. Primary: Start the index service and upload the config with the command: (In Program Files\VirtualWorks\ViaWorks\SOLR\bin)
   solr zk upconfig -z localhost:9983 -n ViaWorksCloud -d C:\ProgramData\VirtualWorks\ViaWorks\Solr\configsets\ViaWorksCloud\conf
   
10. Secondary: Start index service
    
11. Primary: Run the command (this will create 6 shards divided on the two servers WITHOUT replication) (In Program Files\VirtualWorks\ViaWorks\SOLR\bin)
    solr create -c ViaWorksCloud -d "

...

1. C:\ProgramData\VirtualWorks\ViaWorks\Solr\ViaWorksCloud" -shards 6 -replicationFactor 1 -p 8983
   
2. Primary: Verify that logs are OK and the SOLR dashboard now shows 6 shards (http://localhost:8983/solr/#/~cloud)
   
3. Primary: Reindex all data using the Via.repository tool and monitor.
