TrueNAS Scale to Proxmox Migration

Hello! I have decided that instead of using TrueNAS for virtualization
(apps and VMs), I would like to reverse this and install Proxmox, then
NAS software from inside a VM, or something like that. This last part
hasn't been decided yet, but I have a couple issues & questions.

*Please let me know if this would be better off posted in another
sub.*

First, I have several Linux and a couple Windows VMs on TrueNAS Scale.
Some are using UEFI, and some UEFI\_CSM. With the latter, I found it
was quite easy to move the Linux VMs. (I converted the raw dataset to
a QCOW2 file and I'm now serving it over NFS to Proxmox).

With UEFI, I see that Proxmox uses a separate EFI disk where TrueNAS
Scale does not. What are the steps to migrate this?

Next, my Windows 10 guest seemed to migrate well, except it won't boot
in Proxmox. I tried Qemu64 and a few other options until I settled on
"Host." Right now (I now, it's bad... it's temporary!!) I have Proxmox
installed as a VM inside TrueNAS Scale, so the passthrough "host" CPU
should be the same as the host config directly on TrueNAS. Windows
says there was a problem booting and tries startup repair over and
over. Is there something you know of that's usually the cause or do
you need specific details here?

Lastly, I have a few apps (K8S) on TrueNAS:

* Nextcloud / collabora
* Resilio sync
* PaperlessNGX
* Grocy
* Immich
* Jellyfin
* TVHeadend
* Frigate

I have a TON of data in Paperless and Immich for multiple users. I
want to use LXC as much as possible. With that in mind, I decided to
work on Jelyfin first. I created the LXC and copied the data to is,
but it seems to not recognize it and just started as if it was a clean
install. I created a user, then copied data in. It dawned on my that
if I shut down the container, I have no access to the filesystem. so I
SSHd in to it and killed the process... which started again. After
toying around with this more, I came to the conclusion that I don't
know enough to move forward with the migration yet.

Some of the apps above will be easier than others, I'm sure. Some I
can re-create without issue. Others would be a nightmare to start from
ground zero again. I know this isn't a support sub for all of these
apps, but I think I need to start out with some base knowledge on
Proxmox then dig in to the specific app requirements. Like, how do I
shut down the app inside the container, but leave the container
running so I can copy files into it?

*I'm sure I'll have more questions. Feel free to anticipate my future
questions and give me some info. As a FYI of how to approach me, I've
used Linux for decades (it's my primary desktop/laptop OS) and I
deployed VMWare with a SAN for a customer around 2009 (as an
authorized reseller). I've deployed XCP-ng multiple times and
currently maintain networks for customers remotely. I have some good
knowledge, but I'm sure there's holes in it, too - I can't possibly
know everything!*

Thank you!

I almost posted there, but this seems to be related more to a list of
self-hosted apps.
