XMLDB between 8.5 and 9.1

Hi,

We've justed installed AEP9.1 as a new install alongside our existing 8.5 instance (both on the same server).

Can I just export my XMLDB from 8.5 and then import it into 9.1 to transfer the user protocols or does something else need to be done as well (maybe a conversion for 9.1)

Thanks

Joe
