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.

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, etc. In addition, the <code>NEWS</code> file
contains a list of the bugs that have fixed, and comments about any changes
the bugfix required. Please read these files carefully before
starting your upgrade.

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-version.tar.gz
 cd proftpd-version/
 ./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>

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.
