Oracle doesn't know about it, but you can bet the users will notice.
Migratepv -l has been known to have a noticeable effect on I/O, especially
with databases. My suggestion would be to coordinate a time when the system
usage is low(ish). Of course, it depends on the application. That time may
not exist for your environment.
