I'm not sure if I understand your question. So, if you updated DB2 PE
from 8.1 to 8.2 (let's say) you also have to update NSE. On NSE
support page you can find a reference to a document describing "How do
I upgrade DB2 Net Search Extender V8.1 from DB2 UDB V8.1 to DB2 UDB
V8.2?"
Link to NSE support page:
http://www.ibm.com/software/data/db2...h/support.html
The document states, that the update is available for registered users.
You can also download DB2 PE from IBM web site, however DB2 NSE is
included only for Linux... I didn't find Windows binaries.
