What is involved in importing and converting an ARIS 9.8 database backup, in to ARIS Cloud Enterprise; so that the models and objects can be used in the new database?

I hope this is as simple as importing the database (adb file) and then opening it, then copying the needed models and objects to the new/current database.  But in the past it was not so easy to import from older to newer versions, is there anything else required?  If so, how difficult is it?

thanks in advance,
