The flar doesn't retain the mirror or the ZFS (at least Solaris 10 10/06 didn't retain ZFS, haven't tried with 08/07). You'd have to remirror the box and recreate the pools.
One method that may be unpopular here
that I have used in the past, is simply moving the HDs from the v240 to the v440. As long as the disks show on the same c*t*d*, you should be good to go.

As long as the disks show on the same c*t*d*, you should be good to go.Flar does not retain zfs, nor svm configurations, and it is not intended to. A set ZFS disks encapsulates all of the information needed to import the pool, so one would normally either backup and recreate the pool and restore the data on the new pool, or move the disks ( even between dissimilar hardware).
If you use jumpstart you can recreate the SVM information at install time, but not the zpool and zfs filesystems.

zdb(1M) System Administration Commands zdb(1M) NAME
zdb - ZFS debugger SYNOPSIS
zdb pool DESCRIPTION
The zdb command is used by support engineers to diagnose failures and gather statistics. Since the ZFS file system is always consistent on disk and is self-repairing, zdb should only be run under the direction by a support engineer. If no arguments are specified, zdb, performs basic consistency checks on the pool and associated datasets, and report any problems detected. Any options supported by this command are internal to Sun and subject to change at any time. EXIT STATUS
The following exit values are returned: 0 The pool is consistent. 1 An error was detected. 2 Invalid command line options were specified. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWzfsu | +-----------------------------+-----------------------------+ |Interface Stability |Unstable | +-----------------------------+-----------------------------+ SEE ALSO
