I have MongoDB dump file in .bson extension. That i want to import in OrientDB. Should any one know that. Any other way to import DB in OrientDB from MongoDB.
The bson format is a binary format only used by MongoDB. So you first need to export it to a more standard format which you can import into OrientDB. json and csv are the formats you need (which format to use depends on the complexity of your MongoDB documents, if they have a "flat" structure, use csv). See http://docs.mongodb.org/manual/reference/program/mongoexport
After exporting, you can import the file(s) by the ETL tool of OrientDB.
