This thread says that DTII has a different project file extension than DT1 so there’s definitely some additional conversion which takes place beyond just moving samples and files.
Again, we need someone to confirm, but I suspect that transfer is not configured to archive, move, and convert all in the same action.
We either need someone to try it, or someone from support would have to comment since that’s the type of thing they should know, if that limitation does or does not exist.
I understand that the idea would be rather than wait for the entire thing to back up in one action and then convert and upload in another action, if that activity time can be halved by sending straight through and let it take everything in one go.
I think it wouldn’t hurt to send a message to support and see if they respond bc waiting on users might take the same amount of time.
