We are currently using Camunda 7.16 and are in process of upgrading it.
Could you please advise if we should upgrade it to 7.19 or plan it to upgrade it to 8?
Also, please share if there are any detailed documentations available for Camunda 7 vs Camunda 8 architecture.
The DMN engine for both Camunda 7 and Camunda 8 is more or less the same.
The only trouble you might have is if you’ve added a bunch of scripts to your DMN table. Camunda 8 will only support FEEL expressions.
As per the documentation [here](https://camunda.com/blog/2022/04/camunda-platform-8-for-camunda-platform-7-users-what-you-need-to-know/) the support for 7 is for the next 5 years. Could you please advise if this is valid for 7.16 version as well?
According to that list, 7.16 left maintenance recently. I think this is more important to users of the community editions. If you have enterprise level support, then Camunda may provide you with patch-releases.
