Export from which version of Openfire/plugin?
plug-in version 2.6.0
Are you exporting from 4.1.1 server? Or 4.0.0? Maybe it is easier to just copy the database to the new place. What database are you using?

I exported from the server 4.1.1. Database msql. Prompt how to copy the database to a new location
I’m not a DB guy myself, but i think all major SQL products have some sort of moving database tools (like make a dump of current database and then apply/merge it in the new instance).
