Compatibility / Migration with other CFML engines
Whilst Lucee is broadly compatible with Adobe ColdFusion, there are some differences.
Some are for performance reasons, others due to Adobe mis-adopting or adding features whch conflict with Lucee additions to the language. Sometimes it's a trade off between being compatible and respecting our existing users.
Our issue tracker has an acf-compat label which tracks all the known differences.
In addition, with Lucee 6, we decided to change some incompatible implementations and also change some older insecure defaults to be more secure, please refer to the following epic All Breaking changes in Lucee 6

- Lucee Language and Syntax Differences ## Architecture ## Adobe ColdFusion (ACF) is configured in a way that only one single web context is available for a server instance. This means that if you do not secure your single applications they might become vulnerable, you will have to use sandbox security, single instances, etc. This and the fact that you do not have the ability to configure individual CF settings for each virtual host are the major disadvantages of this setup
