Probably not, because disk speed is often the bottleneck at that scale and you haven't said anything about that. But it will take roughly as long as ingesting all the data would take. My guess is that could be anywhere from 1-10 days.
If you find that reindexing is bad for query performance, you can disable it until you are ready. Queries will use backward-compatibility mode, just like they would during reindexing anyway. Then you can run reindexing a little at a time, say on the weekends, until you have caught up. That will take longer, but may impact operations less. -- Mike On May 14, 2013, at 6:04, "Roy Chowdhury, Soumadri" <[email protected]> wrote: > Hi, > > I am upgrading from MarkLogic 5.x to 6, which contains ~2 terabytes data.
