Doubt with ZFS Replace and HD Boot partition.

Hi!

I have a ZFS pool with 4x8TB disks
I´m intended to test a full preventive replace of all of them, with another set of 4x8TB HDs.

I have find this old thread with important instructions. : ZFS Disk replacement (2018)

But i´m in doubt with the boot partition.
Appears that the boot partition resides inside ZFS pool .

Code:
root@pbs1210:/# ls -l
total 114
drwxr-xr-x   4 backup backup    6 May  1 01:28 antes
lrwxrwxrwx   1 root   root      7 Jul 12  2021 bin -> usr/bin

dr-xr-xr-x  13 root   root      0 May  1 08:44 sys
drwxrwxrwt  10 root   root     10 May  1 09:49 tmp

drwxr-xr-x  11 root   root     13 Jul 12  2021 var

However, the 4 original disks have partitions listed as "boot":

Code:
root@pbs1210:/# fdisk -l /dev/sdd
Disk /dev/sdd: 7.28 TiB, 8001563222016 bytes, 15628053168 sectors
Disk model: ST8000VN004-2M21
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes
Disklabel type: gpt
Disk identifier: BDF45E60-3758-4A71-9901-4B9775261073

Device       Start         End     Sectors  Size Type
/dev/sdd1       34        2047        2014 1007K BIOS boot
/dev/sdd2     2048     1050623     1048576  512M EFI System
/dev/sdd3  1050624 15628053134 15627002511  7.3T Solaris /usr & Apple ZFS


Will I need to copy all disk partitions as described in the mencioned post in step 3, and grub-restore in step 5, previous to restore zfs pool?
Code:
Copy the partition table from /dev/sda to /dev/sdc
3) sgdisk --replicate=/dev/sdc /dev/sda

Regards!!
