Export and Importing of User info

I’‘m currently running Openfire 3.31 on Linux using internal Database to connect to Active Directory LDAP. I’‘m being forced to switch to Windows and will be upgrading to 3.3.2 at the same time. I need to save user configs during this migration. I’'ve tried the Import/Export plugin, running Export on the old system, then copying the resulting XML to the new system and then trying to import. I keep getting the following error

Import User Data

The import file does not match the user schema.

The new system is using the internal database connecting to AD as well.

Any hints?

If it is actual problem you can replace at the end of YOUR_USERS_FILE.xml.
