Migrating Data From Failing Pool

OpenZFS
1

I have an old, possibly failing, pool that is raidz1 3 x 8TB. I’d like to migrate all this data to a new raidz2 5 x 12TB pool. Is performing a ZFS send/recv the best option for moving my data? Does anyone have any recommendations for improving my chance of no data corruption?

I do have backups of most of the data. The backups are performed using ZFS send/recv. Can the backups be trusted if the data was sent from a failing pool?

The status of the old pool is:

  pool: media1
 state: ONLINE
status: One or more devices has experienced an error resulting in data
        corruption.  Applications may be affected.
action: Restore the file in question if possible.  Otherwise restore the
        entire pool from backup.
