Currently I run a Freenas 9.10 with a 6x3Tb WD Red in a RAIDZ2 pool filled with 9+Tb of data on it.
I'm planning to upgrade my box, to unRAID, mainly because of the VM/Docker features. So I plan to use the following procedure in order to migrate it:

I'm planning to upgrade my box, to unRAID, mainly because of the VM/Docker features. So I plan to use the following procedure in order to migrate it:
1. Build a new temporary box, with some spare parts and add 2x6Tb new WD Red HDDs.
2. Configure unRAID to my "temp box", keeping the 1out of 2 disks as parity.
3. Copy as many files the "temp box" can hold, from my existing FreeNAS box.
4. The remaining files I'll copy them on a Synology NAS, I already have, that has about 5Tb free space.
5. Move the 2x6Tb HDDs at the existing "FreeNAS" case and boot with the unRAID USB stick I created at the "temp box".
6. Now my "old Freenas" case runs unRAID with 2x6Tb already configured and all the data I previously copied on them . Correct??
7. Add the "old Freenas" 6x3Tb (already in the case) at the unRAID array devices expanding the box. Now the old case has unRAID installed with 1x6Tb & 6x3Tb plus 1x6Tb as parity. Correct??
8. Move the remaining files from my Synology NAS.
9. Add one 64Gb "slow" (spare) SSD disk as cache.
Is there any problem with the procedure? Please note that the existing case, hosting FreeNAS, it will have 2 SATA controllers (1x6 SATA + 1x5 SATA)
T.I.A.
PS: I don't have many simultaneous writes on my NAS. Only a couple of users at the local network and a couple of sporadic remote users. So, I don't have great speed needs (initially). Do you believe I have to add the SSD cache?
