Re: How to move to zFS V5 - painlessly
Don’t forget to check the format_aggrversion if you have it coded in
IOEPRMxx. If not coded, the default on z/OS 2.3 is 5 but the default for
2.2 is 4.

Re: How to move to zFS V5 - painlessly
No. I converted all of our filesystems (except SMPE controlled filesystems)
via the command on all of our systems. Was very quick, chose specific path
hierarchies to do at a time. For all my z/OS supplied ZFS filesystems, I
converted my "maintenance" environment, and then let my cloning process move it
out at maintenance time since all of those are mounted read only, and didn’t
want to chance making them RDWR to do that live.
zfsadm convert -path /your/path/names
The IOEPRMxx entry is just a catchall for me, in case one of my team mates
allocates or has older filesystems laying around that are not normally mounted
anyway.

This is true, but I found that
find . -type d -exec zfsadm convert -path {} \;
comes pretty darn close. The not-faint-hearted may even substitute a / for the
. in the above command.
