Hi I’m planning to update my WSE ver 4.7.7 running on AWS EC2 (byol) on a c3-2xlarge instance WSE 4.8.5. I am aware that the new version of WSE requires OpenJDK Java SE JRE 9.0.4 to work. Because I was uncertain on how to install the new version of Java, I reached out for some technical help and was told that my OS is too old and that JRE 9 cannot be installed and therefore my instance cannot be upgraded I have been running this instance in a production environment for many years and have performed many updates since 4,.4.0 versions without issues It would cause my a lot of consternation and grief if I were to have to abandon this server and have to start from scratch as it is configured for many vHosts and many custom settings Is it possible that the advice I was given is incorrect ? I would appreciate receiving your advice Thanks Anne-Marie ---

It’s indeed possible that your OS is too old to use OpenJDK9. What OS version do you have? (in case of Linux you can check with “sudo lsb\_release -a” or check the os\_release file in the /etc folder) ---

Hi Kabel, Thanks again for your reply I guess i’ll have to bite the bullet and migrate to a EC2 4,8 WSE instance then Best Anne-Marie ---

Indeed, Amazon Linux 2018.03 supports OpenJDK 8 as the highest version and (long-term) support for 2018.03 stopped in June this year. See [https://aws.amazon.com/blogs/compute/re-affirming-long-term-support-for-java-in-amazon-linux/](https://aws.amazon.com/blogs/compute/re-affirming-long-term-support-for-java-in-amazon-linux/) So it’s highly recommended that you migrate to a new Amazon Linux 2 machine with support for OpenJDK 9. If you need help with that; you may post a message in the “Find A Consultant” forums: [https://www.wowza.com/community/spaces/26/find-a-consultant.html](https://www.wowza.com/community/spaces/26/find-a-consultant.html) ---
