You cannot install a BAR file on BB6/7 (there is no 8). The platform architecture for the OS changed from Java to QNX and this changed how applications are packaged. You would need to recompile your code using the BlackBerry WebWorks SDK for Smartphones to generate a COD file.
There is no guarantee that all application features will work since the platform evolved considerably since then, specifically in terms of HTML5 support, changes in config.xml and platform performance. If you use HTML5 features that were only supported on BB10, they will not work on BB6/7.
However, I would expect you will be able to re-use a lot of your application content when re-packaging for the older BBOS. It may require some changes to your app.
If you make use of any WebWorks APIs in your app, please check the supported platforms tables in the API reference guide for compatibility:

Yes you can. Through the BlackBerry World vendor portal, you can create multiple bundles for each application. For each of those bundles, you upload the appropriate file(s) and specify which BlackBerry device model, OS (and even carrier) should be supported.
