Hello!

I’m curious if it is possible to upgrade an existing AMI instance to the latest Wowza version and what are the steps?

Thanks

Yes, you can do it following these steps in an SSH client, starting with logging in as ec2-user:

```auto
>ec2-user
>sudo su -
root>cd /home/wowza/updates
root>mkdir WowzaStreamingEngine-Update-4.0.3
root>cd WowzaStreamingEngine-Update-4.0.3
root>wget https://www.wowza.com/downloads/WowzaStreamingEngine-4-0-3/WowzaStreamingEngine-Update-4.0.3.zip
root>unzip https://www.wowza.com/downloads/WowzaStreamingEngine-4-0-3/WowzaStreamingEngine-Update-4.0.3.zip
root>service WowzaStreamingEngine stop
root>service WowzaStreamingEngineManager stop
root>cd linux
root>chmod +x update.sh
root>./update.sh
root>service WowzaStreamingEngine start
root>service WowzaStreamingEngineManager start

```

Of course you would adjust the file name and update folder (following [this upgrade guide](https://www.wowza.com/docs/how-to-upgrade-wowza-media-server-software-to-wowza-streaming-engine)) name if/as necessary, but the above is the right file name at this writing for the upgrade patch on the [Production Build page](https://www.wowza.com/docs/wowza-streaming-engine-software-updates)

Follow up question … same method works for Wowza 4.1, yes?

Also, will it affect the server monitoring history available through the dashboard?

Thank you
