After upgrading ES to 2.1.0, ES won't start anymore and following lines appear in the log:
```
[2015-11-27 17:18:27,660][ERROR][bootstrap] Exception
java.lang.IllegalArgumentException: Plugin [license] is incompatible with Elasticsearch [2.1.0]. Was designed for version [2.0.0]
```
It seems I have to update the license, but how do I do that?

```auto

Thanks! Since I also had Marvel installed I also had to do a
```
bin/plugin remove marvel-agent
bin/plugin install marvel-agent
```
After that Elasticsearch started smoothly again
