This is to handle the scenario where TV Server has channels before import and there is some overlap between the channels in the XML file and the channels in the TV Server database. The crucial difference between scanning and import is that import uses the channel name (instead of ONID + TSID + SID) for matching. Therefore you have more control over what happens.If all of your exported and "current" (ie. existing in TV Server at time of import) channels have unique names then there should be no merging/updating. The result of such an import would be A + B where A is TV Server's channels before import and B is the channels defined in the XML file. If some channels in the XML file have the same name as existing channels in TV Server at time of import then the result of the import will be less than A + B, because the channels with matching names will be merged.Data is never erased. In other words, the import process doesn't delete all existing channels before importing. However as explained above: if channels do not have unique names then you will experience similar (but not quite the same - merging as opposed to updating) issues as you're experiencing with the scan.Merge (import) = add tuning detail.Update (scan) = update existing tuning detail in-place.You don't want either of these things to happen, so simply ensure all your channels have unique names.Categorically no. <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite1" alt=":)" title="Smile    :)" loading="lazy" data-shortname=":)" />Import does not delete.Export does not delete.Yes, using channel and group names.One recommendation I would make to add to your process: delete all existing channels after export and before starting the next scan. Reduces the chance of getting channels mixed up.</blockquote>
