Folks



Due to Historical Reasons in a Banking product the Customer Signature
Image binary data i.e. JPEG (with JFIF Compression) is stored in a LONG
Datatype.



What is the ideal path to convert this LONG field to BLOB Datatype in
Oracle ver 9.2 & 10gR2?

Is Conversion from LONG to the intermediate CLOB & CLOB onwards to BLOB
necessarily needed?

What might be the performance issues faced as Table size is 1 TB?



Any Docs Links will help



Thanks indeed
