Hi there thanks for posting! When migrating from OnPrem to Cloud you'll need to download your diagrams from the plugin as Visio files and re-upload them to your account. If you take a look at this Help Center article it goes through how you can do this. Hope this helps!

We are contemplating the same move.
Many of the diagrams we've created at our company will need to be completely re-written if that process is the answer.
The issue seems to be with the export to Visio as it does not recognize curved lines line labels and breaks groupings and hyperlinks.

Is there a way to bring in the native LucidChart onPrem format into the Hosted platform?

Hi Jevin, unfortunately there isn't currently a way to bring the native format over but the goal is that with our Visio export you can successfully get a representation of your diagram into Lucidchart.
