It is entirely depend on you and your applications criticality and compatibility, if you want to have new kernel every time. In my environment, it is not so much required. If you can afford little downtime, then Solaris Live Upgrade is a feature in Solaris, where you will update your kernel without having long downtime. It will be up with just a reboot after setting up all required things. I am not sure, if you have Solaris in your option.

ludelete
ludelete(1M) ludelete(1M)
NAME
ludelete - delete a boot environment
SYNOPSIS
/usr/sbin/ludelete [-l error_log] [-o outfile] BE_name [-X]
DESCRIPTION
The ludelete command is part of a suite of commands that make up the Live Upgrade feature of the Solaris operating environment. See
live_upgrade(5) for a description of the Live Upgrade feature.
The ludelete command deletes all records associated with a boot environment (BE) on all defined complete BEs. A complete BE is one that is
not participating in an lucreate(1M), luupgrade(1M), or lucompare(1M) operation. Use lustatus(1M) to determine a BE's status. You can
delete neither the current BE, nor the BE that will become current upon the next reboot. Also, you cannot delete a BE that has file systems
mounted with lumount(1M) or mount(1M).
ludelete does not alter any files on the BE being deleted.
The ludelete command requires root privileges.
OPTIONS
The ludelete command has the following options:
-l error_log
Error and status messages are sent to error_log, in addition to where they are sent in your current environment.
-o outfile
All command output is sent to outfile, in addition to where it is sent in your current environment.
-X
Enable XML output. Characteristics of XML are defined in DTD, in /usr/share/lib/xml/dtd/lu_cli.dtd.<num>, where <num> is the version
number of the DTD file.
OPERANDS
BE_name
Name of the BE to be deleted.
EXIT STATUS
The following exit values are returned:
0 Successful completion.
>0 An error occurred.
FILES
/etc/lutab
list of BEs on the system
/usr/share/lib/xml/dtd/lu_cli.dtd.<num>
