Replacing PCIe cache SSD with a SATA cache SSD temporarily using a USB enclosure?

[Smitty2k1]

My motherboard is mITX with a single PCIe slot currently populated with a PCIe SSD used as a cache/docker drive. My motherboard's 6 SATA ports are all occupied with 3.5" HDDs for the array/parity.

 

I'd like to add a PCIe SATA controller to expand my array. The problem is that I then need to replace the PCIe SSD with a SATA SSD. Can I put the PCIe SSD in a compatible USB enclosure, install the PCIe SATA controller with the SATA SSD, copy the data to the new SATA SSD, and then finally remove the old PCIe (USB) SSD from the array?

Possibly, but why not do it the normal way of using the array drives to temporarily store the data? Every added complication introduces risk to your data.

Ah I didn't even think of that. Thanks, I'll look into how to do this.
