Can proxmox replace ESXi usb stick?

[cat.dev.input.mice]

I wanted to check is it possible to migrate ESXi by replacing usb stick with the one with proxmox.
It kinda worked but I have problem with detecting Mega RAID.

This is Fujitsu PRIMERGY RX1330 M2 and it have FUJITSU PRAID CP400i on board. I also have TX2550 M4 with some newer RAID controller but have similar problems.
Boot proces takes long time and returns problem with detecting RAID controller.

I was hoping to just replace usb stick and make proxmox do migration magic. But it seems it may not be possible.
If it is not possible to do migration this way, I may install new proxmox on usbstick directly on RX1330 (It currently have single SAS disk) and migrate my machines on it. But I may not have so much storage to make full migration. I'm also having huge problems with detecting RAID controller. I even try to install alien and migrate RPM package from Broadcom to make MegaCli work but it also failed to detect any controller.

PVE does not run well on USB sticks. They are worn too quickly. PVE writes much more on the roofs (fuse filesystem represented in /etc/pve, statistics) than VMware.

To solve problems with "FUJITSU PRAID CP400i" it was required to install Proxmox 8.1 and pin the kernel and then make an upgrade. This way, everything works. I would prefer to compile the kernel, but currently I'm not advanced enough to do it.
It seems that Debian kernel doesn't support CP400i any more.

Idea to use USB Stick was a bad idea. It would work if there would be a way to install PVE on another disk.

Yes ;-)

It would work if there would be a way to install PVE on another disk.

I have some "USB to NVMe" adapters and there is "USB to SATA" also. Some of them seem to work stable and wear-leveling is the same as for "normal" connected solid state disks. But I will NOT recommend to go that route as I had enough trouble with this approach to avoid it!
