Update license to old server with expired license

[yl5607]

Hi Community,

It seems I need to update the NoMachine version to renew a license, yet it requires a renewed license to update.

Is there a safe way to manually force update NoMachine installation without a valid license?
I concerning about compatibilities issues if I reinstall without purging the old installation, or user settings loss if I clean reinstall.

Or do I need to purchase a v7 and a v8 license just to update them?

For context:

I encountered a problem that when I tried to update two machines (with v7 and v8) with new license that I newly purchased, and I believe is for v9

I extracted the keys.tar.gz emailed to me to ~/keys on both machines

admin@machine1:~$ sudo /etc/NX/nxserver --version
NX> 630 ERROR: The subscription license on this server has expired.
NX> 630 ERROR: Please contact NoMachine to acquire a valid license.
NoMachine Workstation Subscription - Version 7.6.2
<blockquote>admin@machine2:~$ sudo /etc/NX/nxserver --version
NX> 630 ERROR: The subscription on this server has expired.
NX> 630 ERROR: Please contact NoMachine to acquire a valid subscription.
NoMachine Workstation Subscription - Version 8.11.3

They both errored with –activate:

admin@machine1:~$ sudo /etc/NX/nxserver --activate /home/admin/keys/server-01.lic
NX> 500 ERROR: license type WSS is not valid.
admin@machine2:~$ sudo /etc/NX/nxserver --activate /home/admin/keys/server-01.lic
NX> 500 ERROR: license type WSS is not valid.
Also failed with --subscriptionset:
admin@machine1:~$ sudo /etc/NX/nxserver --subscriptionset /home/admin/keys/server-01.lic
NX> 630 ERROR: The subscription license on this server has expired.
NX> 630 ERROR: Please contact NoMachine to acquire a valid license.
admin@machine2:~$ sudo /etc/NX/nxserver --subscriptionset /home/admin/keys/server-01.lic
Segmentation fault

I suspect I need to update first for them to recognize v9 license.
but they both refuse to update due to expired license.
admin@machine1:/usr$ sudo /etc/NX/nxserver --stop

admin@machine1:/usr$ sudo /usr/NX/nxserver --update
