Is reindex needed when changing database in RTC?
One answer
If you talk about DB indices, it should be moved using Oracle means therefore I suggest there is no need to reindex. As for text indices - it's stored on application server and may be re-used. Only required step is to suspend indexing services as for "cold" backup:
