Some important notes on this upgrade. Firstly, I have followed
this path for a client, and it does work. Secondly, you should
read not just the Upgrade document to which Nicola has linked
(below) but also read the release notes for all intermediary
versions.<br>
<br>
You can find those here:<br>
<a class="moz-txt-link-freetext"
href="https://www.cyrusimap.org/imap/download/release-notes/index.html"
moz-do-not-send="true">https://www.cyrusimap.org/imap/download/release-notes/index.html</a><br>
<br>
It's always best practice to read intermediary release notes, as
changes made in one version (i.e. 2.4.0) may not be mentioned in a
later version's release notes.<br>
<br>
For example, the release notes for 2.4.0 contain this note:<br>
<ul>
<li>All databases are now default skiplist, and ctl_cyrusdb will
automatically convert database type on startup.</li>
</ul>
That's a really good thing, but if you previously set your
database types to something other than the default, then they will
not be converted (maybe you didn't do so, but your packages may
have). As the Upgrade document notes, in that case you should
convert your DB formats to a default <i>before</i> you copy them
to the new server, using cvt_cyrusdb (for example):<br>
<blockquote>
<pre><span></span>cvt_cyrusdb /<confdir>/mailboxes.db berkeley /tmp/new-mailboxes.db skiplist</pre>
</blockquote>
Another big note is that with 3.0.X, the Squat full-text indexing
engine may be replaced with Xapian. Check your packaging or build
for that. If it is, you'll need to rebuild your indexes before
people can use them.<br>
<br>
Similarly, the main Cyrus index scheme has changed between 2.3 and
2.4, and then again with 2.5 and 3.0. You can upgrade from 2.3 to
3.0, and it does so very nicely, but while a 3.0 server can read
the older index formats, you won't get the best behavior or
performance. Run the command 'reconstruct -V max' either just
like that (upgrade all mailbox's indices) or within a script which
walks through your user list.<br>
<br>
Lastly, please get yourself logged in to #cyrus on IRC so you can
get support while you're working. Try a dry run with just a
couple of users or mailboxes, to see what you might face, and
don't be afraid to ask for help. I've been working with Cyrus for
twenty years, and I still ask for help all the time (just ask the
folks on this list!). :-)<br>
<br>
Cheers,<br>

<div>By the way, when upgrading from a 2.3.1X server... can
you directly install a 3.0 in the server and should it
work?. Is it recommended to perhaps go thought the 2.5

<div>When writing the Upgrade documentation (<a
href="https://www.cyrusimap.org/imap/download/upgrade.html"
moz-do-not-send="true">https://www.cyrusimap.org/imap/download/upgrade.html</a>)
we did discuss whether you had to go through intermediate
versions on the way to 3.0, and the answer is a 'no'! You
should be able to go from 2.3 to 3.0 in one hit.<br>

<div>As always, make sure you have backups of your data before
you begin the upgrade.<br>
