<p>Hi Nic,</p>
<p><br /></p>
<p>Sorry for the delay answering... I have been ill and later on holiday, with very very very few time to answer to nothing when coming from illness. Sorry then...</p>
<p><br /></p>
<p>My idea really, was to upgrade to 3.0... So I'm planning:</p>
<p><br /></p>
<p>- Upgrade in place from 2.3 to 2.4.</p>
<p>- Continue giving the service...</p>
<p>- Later setup a 3.0 slave.... all of this <strong><span style="text-decoration: underline;">without</span></strong> doing a reconstruct -V max..... as it seems in 2.4 all works (unexpunge command and so) without it... should say too, it seems the own sync client performs database upgrade....</p>
<p>Jan 3 14:46:02 mx8c sync_client[17186]: Index upgrade: mydomain.com!user.mytestuser.Sarenet-staff.Alberto (10 -> 12)<br />Jan 3 14:46:06 mx8c sync_client[17186]: Index upgrade: mydomain.com!user.mytestuser.Sarenet-staff.Comerciales (10 -> 12)<br />Jan 3 14:46:15 mx8c sync_client[17186]: Index upgrade: mydomain.com!user.mytestuser.Sarenet-staff.Instalaciones-staff (10 -> 12)<br />Jan 3 14:46:25 mx8c sync_client[17186]: Index upgrade: mydomain.com!user.mytestuser.Sarenet-staff.RRHH (10 -> 12)</p>
<p>It seems to anyway be happening....</p>
<p>- When the 3.0 slave is totally replicated from the 2.4 mater... turn the 3.0 as mater, and take a copy of it becoming it slave.....</p>
<p><br /></p>
<p>This way I should have all the platform upgraded without downtimes....</p>
<p><br /></p>
<p>How do you see Nic?. I think it should work... I'm still doing checks anyway.....</p>
<p><br /></p>
<p>Cheers!! Thanks a lot for your time!!</p>
<p><br /></p>

<p>I was trying to upgrade part of our Cyrus imap installation, concretely that one consisting in still 2.3. I was planning to set up Cyrus 3.0. I have seen all works properly except for the unexpunge command because as someone stated here, a reconstruct -V max was needed.The problem is that this reconstruct command, takes ages and I'm not able to keep the service offline so many time. So I have been thinking in the following scenario :</p>

<br /> Egoitz,<br /> As long as you've followed all of the various steps needed to account for version changes, as outlined in the Release Notes for <em>all</em> intermediary releases, then the last step should be the updating of the indexes. Rather than running "reconstruct -V max" on all mailboxes at once, simply run it on subsets. We've done this on large installations without ill effect. You can have the service on line during the reconstruct, and, as you note, have most all functionality present.<br /> <br /> We build a list of users (mboxlist.txt), and then run a cron job, during off-peak hours, using the 'parallel' command like so (from 'crontab -e -u cyrus'):<br />
