V20 Version Upgrades - Top Reasons for Aborting
3 major reasons and other common issues for your upgrade failing.
So after releasing beta 1 of V20 and Update 9 we’ve already had quite a number of upgrades - enough to be statistically significant. And the results are interesting. These are the top reasons for an upgrade to not start:
Number #1 - Insufficient cores - 2+ required
The number one reason for an upgrade failure is the machine not having 2 or more cores. To run 3CX properly, you need 2 cores. 3CX is a real time application that is processing audio - and in some cases video - and cannot afford to have the CPU taken away, even for just a few seconds. This will cause audio issues, provide a bad experience and ultimately affect our brand name. If the machine does not have enough cores, the upgrade will not fail, it will just not run. You will need to upgrade the machine to 2 cores first.
Number #2 - Source list has been edited
The second reason your upgrade will fail is due to the installation of unsupported packages on the ISO. In this case we cannot forecast the outcome of the upgrade so we will not run the upgrade. The only way to upgrade in this case is to do a backup and restore. Some example source lists we found are osconfig_managed_7a718e6aad.list, busylight.list, mysql.list, hetzner-mirror.list.
Number #3 - Not enough RAM - 2 Gig required
Besides real time processing of audio and video, 3CX also hosts a web server with full Web Client. This takes some memory. 1 Gig is nothing these days. To run a mission critical communication system 2 Gig is really the minimum required. So you’ll need to upgrade your system to have sufficient memory.
Environments tested
Process
So what happens when you upgrade? Your system will upgrade from Debian 10 to Debian 11 and then to 12. Depending on the specs of the machine, the size of your 3CX installation, your internet connection as well as whether the system is up to date, the upgrade can take anything from 10-15 minutes right up to an hour or more. Upon successful upgrade, your system will reboot. An email will be sent with the result of the upgrade to the system admin. The email will inform you if the upgrade was aborted, failed or successful.

Other common issues
What to do if upgrade fails
If the upgrade fails, check system requirements, fix and run again. If it still fails, you will need to do a full backup and restore to a new system.
Requirements once again
Note: We gather logs solely for debugging purposes which are deleted shortly after an upgrade is completed. Logs of failed upgrades are reviewed by our engineers to determine potential pitfalls and improve the upgrade process.
Summary
Running a dedicated instance requires a correctly sized instance. For very small installs (less than 5-10 extensions) consider using 3CX SMB or 3CX FREE.?If the customer really needs a dedicated system then they need to understand that the specs will need to be aligned with the up to date and absolutely reasonable requirements. Happy Upgrading!

Get Ready for V20 with Update 9, V18
V18, Update 9 enables easy upgrade to V20.
A simple click of a button will allow you to upgrade to V20 which is going full speed ahead. The option will not be visible in your Admin Console just yet, but as soon as the final is released you will see an “Upgrade” button - as long as you’re on V18, Update 9!
Preparing for V20 - Set that System Owner!
As already mentioned with Update 8 and Update 9 Beta, you need to set a System Owner to be able to upgrade to V20. Systems without a System Owner role will not be able to upgrade.
Take a look at the access level for each role and decide who is the best person for the job.
Other Additions/Improvements
Fixed archiving recordings to SFTP/FTP to not delete local files.
Provider updates:
Note that OS upgrades will be temporarily hidden until the release of Version 20 Final.
