Upgrading Solaris from 2.51 to 2.6

The only services executing on our Solaris server is named or primary DNS. Although our server is not a mail server,
it can receive and send internet Email. I have created a backup system drive incase the upgrade fails

My question is:

Is there anything special that needs to be taken into consideration when upgrading Solaris to 2.6.? Some Admins
stated is best to freshly install 2.6 rather than upgrade from 2.5. Is this true?

-I have done both upgrades and re-installs from 2.5.1 to 2.6.
-I have had no trouble with either one.
-Don't forget to check the release notes for your specific config.
-I am one who prefers a fresh install rather than an upgrade. They are cleaner and have a better success rate.

good luck!

I sysadmin several Solaris boxes at work, most of which we've moved to 2.6.  For each one, we've done a fresh install (which we highly recommend - its a convenient time to clear out all the unwanted garbage that may be polluting your system) without any problems except for one.

On two machines, we have had the system console completely lock up - no response at all, even though the machine was still running fine for everyone else.  We believe (although still unsure) that it may have been the automatic console locking feature that did it.  As mysteriously as it occured those two time months ago, its never happened since.

Also, don't forget to go out and get the latest patches at sunsolve1.sun.com.  

Otherwise no special needs.

Hope this helps!

 Gee, I think the answer has already been covered mostly, by the comments above ...
  I've done both upgrades and fresh installs and all worked fine.  The only thing you need to be aware of are any local changes you may have made to system files ... such as adding TCP wrappers, or so forth.  However, certainly if you did a fresh install, you'd have to keep track of these anyway.
  Apart from that, once you've got 2.6 going, make sure you get the latest patches from sunsolve.
  I think a fresh install is cleaner, but an upgrade works fine ... I guess it depends how well you know your system.  If there's lots of unknown junk floating around -- kill it all, by all means - do a fresh install; but if you set it up in the first place, and things have been kept tidy, an upgrade will be fine.
