How long does it take to migrate db from 8.2 to 9.1 on LUW

When upgrading DB2 LUW from 8.2 to 9.1 the following command is issued as
part of the upgrade:

db2 migrate database <db-name>

Does the migrate command make changes to every data and index page? Any
estimate on how long it takes to run based on number of pages in the
database?

MIGRATE DATABASE changes the catalog, not individual data pages.

As such, migrating a 4Mb SAMPLE database is generally not much different
than migrating a 1Tb data mart. (In my experience).
