Yuo won't need downtime to upgrade sendmail, the only thing will be to restart the sendmail services after upgrading the sendmail.

For more details please refer the following documentation, it tell about prerequisite,what is available in this version, unsupported feature and known problems.

Thomas,

I recently upgraded to Sendmail 8.13.3. The only concern is to make sure that you have modified /etc/sendmail.cf to match your current configuration. I would suggest making a copy of the existing sendmail.cf file then upgrade.
Diff the new sendmail.cf and the old sendmail.cf and apply the changes.
It is better to do that then keep the old sendmail.cf file.

Why _not_ the latest? What makes you think
that the old bugs and security holes are
better than the new ones?

http://sendmail.org/

I quote:

Recent News

Sendmail 8.13.8 is available (2006-08-09); It
fixes some problems introduced in 8.13.7, as
well as some other bugs. [...]

Sendmail 8.13.7 is available (2006-06-14); it
contains a fix for a potential denial of
service problem [...]

Sendmail 8.13.6 is available (2006-03-22); it
contains a fix for a security problem
discovered by Mark Dowd of ISS X-Force.
Sendmail urges all users of sendmail 8 to
upgrade to sendmail 8.13.6.
Notes:
This affects every sendmail 8 version
before 8.13.6.
At least one party is actively working on
developing a public exploit. Please upgrade
as soon as possible.

[... and on, and on, ...]

The steps to upgrade would probably depend on
details like whether you start with a patch
kit from HP or a source kit from
sendmail.org.

Shalom Thomas,

It's not really all that hard.

Back up all the configuration files in /etc/mail and then swinstall the depot from HP http://software.hp.com

You back up the configuration files merely in case something gets trashed. The upgrade deals with several major security faults, so there may be conflict with any customizations you have made to the configuration files.
