Migrate Z-Stick from 5 to 7 trying to backup nvm using Z-WaveJS UI but no file created

Gooday. I have a Z-Stick series 5 and want to migrate my entities to a new version 7 Z-Stick. I go into Z-Wave JS UI, advanced and select backup, it says:

API backupNVMRaw called - Close

But never shows me a file or path to find a file. I checked downloads but no new file. Am I missing something?

Versions:
zwave-js-ui: 9.20.0
zwave-js: 13.3.1

Edit: This is running HasIO in a Virtualbox VM.

The only other comments I can find are dated 2022.

Thanks,
Glenn.

Ok, solved - not patient enough. This just appeared in the console:

Sorry to wake everybody up.

Edit: Interestingly it seems to have frozen at 56% after about 30 minutes. I’ll be patient and see what happens.

I am trying to backup NVM using the latest UI but the backup never completes. It sometimes gets to 2%, sometime 32%, the best it has done is 56% but it just stops there, no error and sits on the same percentage. I have left it for an hour. I can use the Z-Wave PC Controller 5 to back it up, so the stick, usb etc is ok. I only have 14 devices, so no major load.
It also stops me from including or excluding devices as those tasks have to wait for a backup to complete.
The Z-Stick is version 1.2.
Thanks,
Glenn.
