KnowledgeTree migration to Office365

I need a tool to migrate in batch a KnowledgeTree Version 3.7.0.2 (Community Edition) Document Repository to Office 365 (Sharepoint 2013). The tool must perform the following actions: * Navigate through all folders in KnowledgeTree and replicate the folder structure in a Document Library in Sharepoint * Copy all files to Sharepoint Users, workflows and permissions are not to be migrated. Optionally, it would be very useful that the software would also migrate: 1) document metadata (no customizations) 2) all document versions The tool can use Open Source code and can be released in whatever license you want, providing that we are entitled to use it one single time. The migration of the data will be handled by us, your job is only to develop and test the tool.
