Upgrading from 0.5 into a Virtual Machine with shared folder to import

I have an Ubuntu machine with 1TB ssd (main disk) and 1TB hdd (secondary disk) running Umbrel and I finally have the time to upgrade it. I want to keep using the computer for other uses.
I’m following the instructions on: How to update from umbrelOS 0.5 to umbrelOS 1.1 on Linux devices which say to create a tar of the entire /home/user/umbrel folder, then copy it into the VM and then extract it.

But the tar file is huge! It contains the entire blockchain + Electrs indexing…

Instead, I’ve moved the /home/user/umbrel folder to the HDD disk, and then mounted it using VirtualBox’s Shared Folders into the virtual machine as /home/umbrel/umbrel/import (also added the umbrel user to vboxsf permission group so it can read all the files in /home/umbrel/umbrel/import.

Unfortunately nothing really happens, even after restarting the machine. Going to http://umbrel.local shows the signup page, not the login page.

Where can I see logs of the import process? Can I try to execute it manually somehow? Will it better to try a newer iso than 1.1.2? Thanks.

Ok, mounting doesn’t work, but copying the files does.
From a brief look at the code, it seems like the migration process tries to move the /home/umbrel/umbrel/import folder - and this might have caused a problem when /home/umbrel/umbrel/import was a mount to a different hard-disk.

So I just copied the files with rsync, and after ~4 hours I restarted the VM and it worked.

No need to be worried that the content in /home/umbrel/umbrel/import is too large and will caused the migration to crash - the migration moves the files from the import folders and doesn’t make a copy of them.
