<br><br><div><div id="SkyDrivePlaceholder"></div>> Seen data is only stored in .seen files for shared or other user<br>> mailboxes. The seen data for the mailbox owner is stored in the<br>> cyrus.index. This has two benefits:<br>> <br>> 1) lower IO for the most common case. We need to update the<br>> cyrus.index file anyway to record the new MODSEQ.<br>> 2) owner seen becomes shared seen if you switch to shared seen<br>> mode on the mailbox, so that you don't wind up with one huge<br>> file full of shared seen data if you have a lot of shared<br>> mailboxes.<br>> <br>> Seen files were actually a lot of extra IO on 2.3, small files<br>> with multiple fsyncs!<br>> <br>> Bron.<br><br>Hello,<br><br>I am beginning to see this. Is there a mecanism to read from these .seen files to recover this data during a migration? Because from what I am seeing, if I move a .seen file from the old server, the new server never reads from it and all my seen data is lost.<br><br>Thanks in advance,<br><br>Ron.<br><br></div>                                            </div></body>
