 I went from FreeBSD 5.4R to 6.2R. On my drive, I had two partitions that
I wanted to keep without losing.

 I was able to walk through sysinstall and slice up the drive as it was
before, and when all was said and done, my two partitions that I was
hoping to keep were intact (mind you, I did make backups just in case!).

 I was very pleased, and the upgrade to 6.2R was painless.

 (As a side note, I opted to wipe the other slices and do a fresh install
of the OS and apps while retaining my two data slices).

 Your mileage may vary

Brett,
Yes, 6.2 does but there are features that were added to UFS2
(softupdates, file size limit raised past 2GB?) which make it  
a much

better filesystem infrastructure than UFS1.


The things you mention (softupdates, large files) were and are well  
supported
with UFS1 too.  There were not really much features added with UFS2  
(support

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  
the

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.  
Reference: .
