Recreate "base" pool

[NoTHX]

Hello,
I have a small RAID1 pool from two SSD drives, used (among others) for iocage and system dataset. I'd like to "expand" this pool to six drive RAIDZ2. As ZFS does not support migrating between RAID types I understand I have to destroy original pool, add&replace drives and make a new one. What is best method for achieving this? For other reasons I'd like to keep pool name (and dataset structure of course) including relevant config settings, like shares etc...

Can I do it within this NAS (moving system dataset and iocage away), or is it viable/safer to take a snapshot to file, create this pool elsewhere, restore the snapshot there and simply rely on that the NAS box will autoimport such "implanted" pool without issues?

Howto: migrate data from one pool to a bigger pool

There have been a lot of posts recently about how to move data from one pool to another. Usually it's because folks want to upgrade to a much larger pool and the drive-by-drive resilvering process will take too long. I've recently gone through this as well. Here are the steps that I followed...

That process allows for it within the same NAS... assuming you have the free connections/slots for it.
