I know depasseg has a similar thread https://forums.freenas.org/index.php?threads/best-method-for-upgrading-pool.38962/#post-238554 but I thought I'd ask for some thoughts on my specific task.
I have 2 FreeNAS machines. My production machine (as per signature) has 7x4TB drives in RAIDZ2 and is approaching 75%. My backup machine has 5x4TB drives in a stripe and is about 70% full.
The production machine (APEpool1) is replicated to the backup machine (APEpool2) every night and each dataset has a a number of periodic snapshots (kept weekly, monthly and 6 monthly) and a replication task.
I was planning on destroying the pool APEpool1 to add another 4TB drive and create a new pool with 8x4TB in RAISZ2.
My plan goes something like this:
Thoughts on where this might cause me problems, or any tips and tricks would be much appreciated.

My plan goes something like this:
- Check APEpool2 datasets to check everything has replicated successfully from APEpool1 (the sizes are pretty similar, but in most cases not identical which I was hoping was down to the compression?)
- Destroy APEpool 1 and add new disk
- Create APEpool 1 with 8x4 disks
- Create replication tasks on APEpool2 to APEpool1 (will I be able to use the snapshots that already exist from APEpool1, or will have have to create new periodic snapshots on APEpool2?)
- Check APEpool 1 datasets and check everything has replicated from APEpool2
- Set Jail configuration root path to APEpool1/jails
