@JorgeB Thanks for the answer. Final Capacity is basically one of my question that I couldn't find out. Can I just add the four drives to get a total of 1dev8Drives? The calculators in the net roughly spit out 65TB capacity for that config when building it from ground up. But will I be able to achieve the same capacity by adding the 4 drives later? Edit: After reading a little bitmore I think the feature I'm looking for is zfs expansion. Question is is that already implemented in the current V7 Release?

Hello everybody, I have made a plan in my head to do an "all in once" Upgrade / Migration. Current System is an Unraid 6.12.13 with 4 Disks (2 Disk Parity) Array --> Goal is to move this to an 7.0.0-rc.1 Server and the data from the array to an 8 Disk ZFS Raidz2 Pool. Why? Because I wanna use Full ZFS for longterm Data Storage and also the new Mover ability to move from pool to pool. Disks are all 12 TB same Model Plan: Add 4 New Drives into existing Server Create and ZFS RaidZ2 Pool with 4 Disks Copy all Data from Array to Pool Inplace Upgrade from 6.12 to 7.0.0-rc.1 In Case this works well --> Delete the Array Add the old 4 Free disks from the Array to the ZFS Pool to get more Storage I think this should be pretty doable with a moderate risk of data loss I have two main questions: Is there any Big Showstopper that i have overlooked? Can i easily expand the ZFS Pool over the GUI or do i need CLI Magic to make this happen? Thanks in advance for your input and recomendations. Greetings
