Usually by the time the customer has informed us of this, or realized they are missing data, they have used 3.x for too long to risk changing primary data like projects, variables etc. \r\n\r\nIt would be great if we could have a flag for the migrator to only import history that doesn't exist. So projects, releases etc that do not exist within the 3.x instance would be created but if they do exist then they would be skipped instead of overwriting.\r\n\r\nI have a bunch of sources for why this is relevant, but they aren't super specific to creating this. I have asked for a couple of databases so we could test their specific cases."}}
