I have a server which I am considering upgrading from 4.11 to

upgrade is completed. I'd rather not have to reformat it unless
there is a
significant advantage to doing so. Does 6.2 work properly with
disk format? Is there any reason to take the time and effort to
the data and restore it to the new format? Is there anything I'll
be careful about if I upgrade just the system disk?
Yes, 6.2 does but there are features that were added to UFS2
(softupdates, file size limit raised past 2GB?) which make it
better filesystem infrastructure than UFS1.
The things you mention (softupdates, large files) were and are well
with UFS1 too. There were not really much features added with UFS2
for very large disks (> 1 TB) and some support for extra flags and
attributes are what I can think of right now.)
There is not really any significant gains to be had from converting
existing file systems from UFS1 to UFS2.
FreeBSD 6.2 should work just fine with the older disk.
Sorry. I meant "snapshots", a feature of softupdates, which according
to McKusick (dev author of softupdates?) are available post 5.0.
