The WebTrends visitor ID is generated by WebTrends itself, right? So
once you're 100% on AA, you will never be able to use that WebTrends
visitor ID any more.Personally, I think you can import your WebTrends
visitor ID into the required "visitorID" field in the batch file(s). But
for all new data, you should just rely on the visitor ID that AA uses,
whether it's ECID or something else.Point is, you can leave your report
suite's timestamp setting alone.
