Update from 15.5 to 16

[Tomas Raska]

Hello,

how can I update (upgrade) from v 15.5 to v16 (3cx on Windows Server)?
3cx show me : Your System Is Up To Date

And v16 have same architecture?
Because our subnet range is not RFC standard and in v15.5 I changed C:\Program Files\3CX Phone System\Bin\nginx\conf\nginx.conf and I added here our subnet.

Thank you.

Do a full backup - move the backup file outside of 3CX folders else it will get deleted when you uninstall.
Uninstall v15.5
Install v16 using the backup from above

On the subnet question, I doubt anyone knows so it maybe trial and error
