Migration from 8.6 failure

[HostaHost]

Any ideas what this error means?

<?xml version="1.0"?>
<execution-result status="error"><message code="InternalDtdValidationFailed" severity="error"><context>void plesk::validateSchema(plesk::tXmlDocument&amp;, const std::string&amp;)</context><file>./xml_parse.cpp</file><line>412</line><text>Failed validation of the document with its internal DTD.

Oh yeah, and the continue button on the page where the error shows the migration has failed is not clickable.

I have this error too in Plesk 8.2.0. I do not migrate some domains. Any ideas?

So far I think it fails to migrate from 8.x if there are subdomains that use their own unique FTP usernames and if there are web users defined.
