Sage 50 migration to Sage One Business Cloud

I started using Sage One Business Cloud around May / June this year. For majority of clients the migration process was straight forward and Sage provided me with a Migration Tool. However, the half dozen clients on Sage 50 and using Foreign Trade - we had issues. Sage support and account manager said after I subscribed to Sage One that currently there is no way to migrate these clients and there is no current plan to build a migration tool to deal with the Foreign Trade transactions.

Anyone else having this problem? Any suggestions?
