zabbix server update and postgresql+timescaledb update

[ruryx00]

hello everyone i have an installation of zabbix server in version 6.4 using postgresql+timescaledb as database.
I would like to perform an update of both the server and the database without losing my data.
more information about my setup:

• Postgres 14.2
• Timescaledb 2.12.2
• zabbix server 6.4
• Ubuntu 22.04 LTS

to which version I would like to upgrade:

• Postgres 16
• Timescaledb 2.14/15
• zabbix server 7

Can anyone explain in detail what is the procedure to do this?
thanks in advance
