I also use Linode, but I have done a similar upgrade without creating a
second VPS and migrating the database. Perhaps that's living a bit
dangerously, but it worked for me. I used Linode's backup feature to
give me an escape route if something went wrong. Briefly, here's what
I shutdown the machine completely, and created a manual backup of the
entire machine. After rebooting, I did the upgrade from Debian 8 to
Debian 9. This was done using various apt commands. I recall that I
had to use Linode's out-of-band ssh service instead of normal ssh at
one point, because the upgrade brought down Debian's network service
After the OS upgrade, I made another manual backup of the entire machine.
I also made a backup of the Koha database and configuration, and copied those
files to my own laptop. Finally, I did the Koha upgrade using the usual
'apt install koha-common'.
