Can I still open projects in PMxLite that I previously created in older versions of the full PMx?

Yes, you can open previously saved PMx project in the streamlined PMxLite user interface. Any advanced settings or options that were applied when the project was saved in PMx will be retained when the project is opened in PMxLite.

For example, assume you created and saved a PMx project with age classes specified as months rather than years (an advanced option hidden in PMxLite). This project will open in PMxLite with age classes still specified as months, but the advanced option to adjust age class length will be hidden in the PMxLite user interface.
