As this is crucial (and possibly dangerous, e.g. disk structures differ), and as it's a one off exercise, I'd do it manually and not by script/automated parsing.

SYNC(8) Linux Programmer's Manual SYNC(8)
NAME
sync - synchronize data on disk with memory
SYNOPSIS
sync [--help] [--version]
DESCRIPTION
sync writes any data buffered in memory out to disk. This can include (but is not limited to) modified superblocks, modified inodes, and
delayed reads and writes. This must be implemented by the kernel; The sync program does nothing but exercise the sync(2) system call.
The kernel keeps data in memory to avoid doing (relatively slow) disk reads and writes. This improves performance, but if the computer
crashes, data may be lost or the file system corrupted as a result. sync ensures that everything in memory is written to disk.
sync should be called before the processor is halted in an unusual manner (e.g., before causing a kernel panic when debugging new kernel
code). In general, the processor should be halted using the shutdown(8) or reboot(8) or halt(8) commands, which will attempt to put the
system in a quiescent state before calling sync(2). (Various implementations of these commands exist; consult your documentation; on some
systems one should not call reboot(8) and halt(8) directly.)
OPTIONS
--help Print a usage message on standard output and exit successfully.
--version
Print version information on standard output, then exit successfully.
-- Terminate option list.
ENVIRONMENT
The variables LANG, LC_ALL, LC_CTYPE, and LC_MESSAGES have the usual meaning.
CONFORMING TO
POSIX.2.
NOTES
On Linux, sync is only guaranteed to schedule the dirty blocks for writing; it can actually take a short time before all the blocks are
finally written. The reboot(8) and halt(8) commands take this into account by sleeping for a few seconds after calling sync(2).
This page describes sync as found in the fileutils-4.0 package; other versions may differ slightly.
SEE ALSO
sync(2), halt(8), reboot(8), update(8)
