Using remote copy over other
data migration methods provide the following advantages:
- Minimal application down time — Remote copy updates the
remote migration copy at the same time that you update the application.
When the migration copy is complete, you simply quiesce application
programs, ensure that all updates are on the migration volumes, and
start up the application using the new volumes.
- Minimal application impact — Application performance is
not affected during the migration. You can continue to update data
normally, with a pause to switch to the new volumes.
- Migration automation — There is less operator intervention
that is required to perform the migration because there is no need
for a dump and restore process.
