Hi @bluemeadow, Welcome to the forum! 
The answer is yes.
When you have a valid version of the Rhino plugin, you can use the PO_Model component to import the Pollination model from Rhino to Grasshopper. It translates the Pollination model to a Honeybee model under the hood.
You can also save your model as an HBJSON file and import it to Grasshopper using the HB Load Objects. As long as you save your model to HBJSON before your license expires you will be able to import the model into Grasshopper.
In both approaches, all the geometry and metadata will be kept. One of the strengths of the Pollination ecosystem is that we treat interoperability as it should be. Your model is your model!
