I have a requirement to create a smart service, which writes a file from My System Folder (Source) to Appain Knowledge center (Destination).

How to create a "versioning" on a file in knowledge center (Destination) when I try to write a duplicate file from Source location ?
How to check if source file is duplicate (already exists) in knowledge center based on this it creates a versions to the file in Knowledge center ?

I have a trouble in doing this in smart service code.
Can anyone suggest how to achieve it .

I have only this right now:
Write the file of ByteArrayOutputStream to ContentOutputStream

Document doc = new Document();
                    doc.setParent(destinationfolderId);
                    doc.setName(fileName);
                    doc.setExtension("pdf");
                    ContentOutputStream cos = contentService.upload(doc, Content.UNIQUE_NONE);
                    cos.write(boStrm.toByteArray());
...

There are multiple plug-ins in the Shared Components section that end-up creating new documents or new versions. Most of them handle this via node input so at design time you determine whether the node is going to override an existing document or create a new one. This is the safest way to go.

Have a look at the examples under forum.appian.com/.../all

Some examples would be:
