Are previous versions of NVivo forward compatible to this new NVivo suite? If so, to all versions?
Projects created in older versions of NVivo can be opened and worked within NVivo 12. Projects from older versions that are opened in NVivo 12 will be updated to an NVivo 12 project format. Please note that projects created in NVivo 12 for Windows cannot be opened in earlier versions of NVivo.
If you are sharing project files with others, you will need to be using the same version of the software. If a project item is not supported in the version of NVivo 12 that you have chosen to work with, you will not be able to work with that item in the software. You may choose to upgrade your version to access additional functionality.
