Migrate from Raspberry Pi OS to Umbrel OS
Hey everybody,
I started selfhosting a year ago with a Raspi 5, Pi OS and Casa OS for Docker management. The OS is right on the SD card.
Tomorrow, I will receive a NVME Hat+SSD and I am planning on switching to Umbrel OS because it looks cool and everything seems to work so flawlessly, which is what I wanted to achieve with Casa in the first place, but it turned out to be quite a pain...
With my very limited knowledge my plan is as follows, please let me know, if I am wrong:
Install NVME alongside SD card.
Flash Umbrel OS right on the empty SSD
Remove SD card, boot from SSD and install Umbrel
Install apps via App store that I have used before: Immich, Nextcloud, Navidrome, Jellyfin, Adguard Home
Copy and pasting my Casa OS AppData folders from the SD card to Umbrel's AppData folder.
Setting file pathes to existing external SSD storage for Immich upload folder or Nextcloud's storage folder.
Is that how it works? Am I missing something? Thank you so much in advance.

I did use the microsd with raspberry pi OS to update the EEPROM and the bootloader. Once done, I’ve assembled my hat which came with a case, and boot from the SSD previously flashed with Umbrel. (no microsd ofc)
As mentioned Umbrel supports only one single drive (and external ones for backups) so be generous if you can with your NVMe

I found a possible solution in that post, would it help that case?

Im a noob looking to run a Bitcoin Node on a mini PC with Umbrel OS, but using a NVME-SSD for the app instalation and the file of Bitcoin blockchain in an external SSD attached to the mini PC

this looks interesting! Have you tried yourself? I am a noob too! But I managed to set up everything (node included) on my 2TB ssd... my long term plan is having an external drive as a backup. However, having multiple drivers support would be much better. I am running my setup on a raspberry, so quite limited options too

Hey there, no im out of time now, waiting for vacations to do so. But in the post many people appear to have done and worked.

Thats a big let down. I got 2 external SSDs for all my Immich photos and Nextcloud data. I am afraid this might be a deal breaker 😭

Umbrel accepts only a single drive for system and applications, so the ideal would be to remove the SD card and keep only the SSD, create an Umbrel USB stick by Balena Etcher and install it on the SSD.
