We have license and we use PDF.js Express Plus - 8.0.1

We save annotation data in “xfdf” file, but now we would like to use realtime-collaboration  
So can we migrate or store our xfdf file data in realtime-collaboration.

Hi there,

I am not really sure what you are asking - [this guide](https://pdfjs.express/documentation/collaboration/overview) is probably a good place to get started though.

If you have a more specific question, please create a new ticket and fill out the issue template correctly.

Logan
