If your solution is configured to leave copies of documents in SharePoint, then your library's versioning settings may prevent you from re-archiving a document to OnBase. If versioning is turned on for your library, then you cannot re-archive a document to OnBase until the version number on the document in SharePoint has changed. If you try to re-archive a document that hasn't changed, the following error is displayed: The document revision has not changed since the last archive.
