Frank,

We do not re-create all the container files since this would not be possible if they where stored on Centerra in compliance mode. We do have to re-index all the messages to update the Domain field in the index (new feature in 4.7). Keep in mind that you only have to use the database upgrade tool if you want to be able to do domain searches on theses volumes.

Hope this answers your questions.

Thanks Stephan
So is the time required to run the utility comparable to simply reindexing the volume?

Yes, in a way it is. Each volume has to be opened each message has to be re-read.
