I started my FreeNAS wrong from the beginning now what?

Dell PowerEdge R510 32GB RAM
TrueNAS 13.0-U5.3

So, after reading all the literature, I know that the method I used to configure my OS and the initial server was incorrect, but I used the proper hardware for the containers. Unfortunately, this was after the fact, and I don't want to lose my 80TB of content. Is there any way around this where I can append a serial number to the mfid# storage devices and shift some data around to correct the overall design?

There is no recovering from this without destroying your pool. Hardware RAID is fundamentally incompatible with ZFS' functionality and is a very good way of losing your data.

You will need to setup a pool with direct-attach disks (large enough for your data), which means you will need HBAs to replace the RAID controller(s).

I was afraid that was going to be the answer. I appreciate the reply; I only wished for a temporary workaround to save my movies.
