sudheer dasari 9 how we can reparent attachments & notes. using data loader
i have one object which contains 20 lacks of records with each record having 2 r more attachments, i need those records and attachments to copy another object, every thing is done except attachments can anybody suggest me.
Instead of manual mapping, you can map id's using excel vlookup function. But you have more than 20 lacks records, writing a custom code is better option. Just one suggestion, write your logic as such which will not hit any salesforce governor limits.

You cannot reparent attachment and notes using data loader. This is a standard salesforce limit.
One way to do this is
1) Export the attachments/notes from source object,
2) Change parentId to destination object id,
3) Import the attachments/notes
4) Delete attachments/notes from the source object.
