Thanks for the info.

What may break are programs that assume you are not going to have file
names longer than 14 characters.  For example, if <app> is only able to 
import files with names <= 14 chars, it'll have a problem with something
longer.  Also, programs that assume that file names are truncated at the
14th character (which is against what standards say) may have a problem.

In general, unless the software is incredibly old, you won't have any
problem.

P.S.: Of course, backup your system before attempting it, just in
case something dumb (like a power failure) happens while you're doing
the conversion.

There are a very few system utilities that may break in very obscure
circumstances (since they're forced to support both 14-character and
254-character filename limits), and there are a few third-party
applications (WordPerfect comes to mind) that have had problems with
filenames being >14 characters.  It's quite safe to make the switch,
however, using convertfs().

I had no problems converting mine.  It IS a one-way one-time proposition
however.  The reason for the warning is "disclaimer".  My advice is
ARCHIVE BACKUP FIRST!

Absolutely, positively don't use SAM to convert; use /etc/convertfs instead.
Use of SAM to convert will corrupt your disk. It's reported.

Beware if you are running the HP ME CAD software ME10 or ME30.  They have
accomodated long filenames for four years, but they can get into trouble
CHANGING from 14-char filenames to long filenames.  This results from a
method used by ME10/30 to actually provide 40-char filenames on 14-char
systems.  There is no problem unless drawings created and named with the
ME10/30-specific method are used on a long filename system.

I left that division of HP a few weeks ago and used to support ME10, but
this is my own opinion and not HP's.
