<p>
Upgrading <code>proftpd</code> is usually a straightforward process, but
as with any upgrade, double-checking that the upgrade will not break anything
is a Good Idea.

<p>
Recent ProFTPD releases have a <code>RELEASE_NOTES</code> file in the
source distribution that documents the changes in that release, including
new configuration directives, new contrib modules, deprecated directives,
special instructions, <i>etc</i>.  In addition, the <code>NEWS</code> file
contains a list of the bugs that have fixed, and comments about any changes
the bugfix required.  <b>Please</b> read these files carefully before
starting your upgrade.

<p>
One safe way to test the upgrade is to compile the new <code>proftpd</code>,
and test it out on your existing configuration file before actually installing
the new version into the &quot;live&quot; location:
<pre>
  $ tar zxvf proftpd-<i>version</i>.tar.gz
  $ cd proftpd-<i>version</i>/
  $ ./configure ..
  $ make
  $ ./proftpd -t -d10 -c /path/to/proftpd.conf
</pre>
The &quot;<code>./proftpd</code>&quot; means to use the new
<code>proftpd</code> binary compiled by <code>make</code>, but not yet
installed.  If the new binary reports errors, make a copy of your existing
<code>proftpd.conf</code> file, keeping the old one as a backup:
<pre>
  $ cp /path/to/proftpd.conf /path/to/proftpd.conf.new
</pre>
Make any needed changes to the <code>proftpd.conf.new</code> file, until
the new <code>proftpd</code> binary reports a successful syntax check:
<pre>
  $ ./proftpd -t -d10 -c /path/to/proftpd.conf.new
</pre>

<p>
Once everything is configured the way you like, install the new binary and
configuration file:
<pre>
  $ make install
  $ cp /path/to/proftpd.conf /path/to/proftpd.conf.old
  $ mv /path/to/proftpd.conf.new /path/to/proftpd.conf
</pre>
Now do a stop/start on <code>proftpd</code>, and the new version of ProFTPD
will be running.
