Hi, I'm trying to perform a rolling upgrade (5.6 to 6.6) on 3 nodes. I successfully upgraded the first node according to the instructions in: [https://www.elastic.co/guide/en/elasticsearch/reference/current/rolling-upgrades.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/rolling-upgrades.html)

I also started the new version of kibana on that node (node 1).

Now, I'm trying to upgrade the next node. I see that it is shutdown, so i cant disable shard allocation on it.

When I try to directly start elasticsearch 6.6 on this node (using the SAME config as the prev node), i get this error:

```
[2019-03-14T15:16:08,287][ERROR][o.e.g.GatewayMetaState] [vm-63f1-8c50.nam.nsroot.net] failed to read local state, exiting...
java.lang.IllegalStateException: index and alias names need to be unique, but the following duplicates were found [.watches (alias of [.watches-6/wi5P71H7RS-ZbuW_q_JjCA]),.triggered_watches (alias of [.triggered_watches-6/LQHW41b-SgGGLUt-o5reKQ])]
```

It's easier if you can keep things in one thread. Let's continue the discussion here [Rolling upgrade problem](https://discuss.elastic.co/t/rolling-upgrade-problem/172408) 🙂
