Hmmm - I've got a fairly old copy of the zpool cache file (circa July), but
nothing structural has changed in pool since that date. What other data is held

in the newer filesystems.
Cache file keeps pool configuration so zfs can quickly open it upon reboot. If
there were no changes to the configuration of pool vdevs, then it should
describe good config.

Any particular procedure required for swapping out the zpool.cache file?

If you have that file, ZFS will happily mount a pool on boot without its slog
device - it'll just flag the slog as faulted and you can do your normal
replace. I used that for a long while on a test server with a ramdisk slog -
and I never needed to swap it to a file based slog.
However without a backup of that file to make zfs load the pool on boot I don't
believe there is any way to import that pool.
