Luis Cabaceira (Solutions Architect @ Alfresco) contacted me for contributing in the project with a brand new connector dedicated to massive contents migration against an Alfresco repository.
Alfresco provides a Bulk File System Import tool that allow to import contents written in its own format in the file system:
Basically binaries with also versions and metadata written in the Java Properties format.
The most important functionality provided by this tool is the in-place feature.
Using it you can import contents directly inside the content store of Alfresco in the file system and then import only nodes without the need to upload/stream binary contents.
This new ManifoldCF connector will convert and write all the crawled contents in the BFSI format in the remote file system.
In this way the extracted content can be dropped directly in the Alfresco content store and then running the BFSI tool the repository will import contents without uploading/streaming any binary.
This is important because the BFSI tool is developed and fully supported by Alfresco.
If some development will be required for adapting it with ManifoldCF, this will be done by Luis with also my support.
