Migrating to self hosted but unsure of the constraints and compatibility

[Stringmusic]

Greetings,
I am working at getting ready for a migration. The issue is the OS compatibility i.e Debian Bullseye and the RAM constraints of the server.

Have the bugs been worked out for Debian bullseye or greater?

How much ram is needed per sip trunk and number of simultaneous users?

How many CPUs are needed per sip trunk and number of simultaneous users?

And is a domain name needed to run a 3CX instance safely?

Thanks,

Hi @Stingmusic,

The issue is the OS compatibility i.e Debian Bullseye and the RAM constraints of the server.

Deb 10 is the only supported OS for v18 currently.

As for your other requirements, have a look at the Hardware Requirements listed here: https://www.3cx.com/docs/recommended-hardware-specifications-for-3cx/

Sorry for the delay, I was away. Thanks for clarifying. Yes, my CPU questions was very basic, I should have prefaced the type of CPU; however, the link provided goes into further detail about the different types of CPU and their performance.

About Debian, yes Deb 10 is recommended however, when a OS is near EOL it's good to start planning ahead as security updates may not be backwards compatible.

tentitive solution: is use Deb10 and not update it

thanks for the excellent references and answers.

Best,

Use the Debian iso image to install the new 3cx server https://www.3cx.com/docs/manual/installing-debian-linux-pbx/

Backup your existing server using fqdn and license key. Copy this file locally as it will be required later
Shutdown your existing server
Install 3cx using the iso image
When running configuration , select restore from backup

Guessing you are moving from cloud setup to self hosted, you will need to reset all the phones and reprovision them For local lan

Set updates to auto, and the system will update the operating system and 3cx - this is the supported way of keeping your system up to date.

Debian 10 is supported for another 30 months... it's not near EOL
