There is an option to select one file, Copy Database, and specify the location on the local machine. However as soon as I select more than one, the Copy Database option is greyed out. I have ~500 mailboxes to export, totalling 2TB of space.
I have full admin access, I can use the Domino console. I can't find any info at all anywhere.
If you have remote login to the server, you can share a local folder and copy that way. But you'll need to shut down the Domino server while doing that in order to make sure the files are closed. If you can't/don't want to do that, then your option is to write a short piece of LotusScritp that uses NotesDatabase.CreateCopy to copy the files. You may want to use the NotesDbDirectory class in order locate the specific files, but it wouldn't be necessary if you already have a list of filepaths for the databases that you want to copy.
