upgrading the 3cx phone system from an older version to 3CX v15.5

One of the biggest advantages of choosing a 3CX Phone System is its flexibility and robust feature set. Being a software-based phone system that can be hosted on a variety of platforms as well as in the cloud makes it an extremely powerful communication platform for business. However, as with all software systems, with constant innovation comes the need to keep software up to date.

Are you on an older version of 3CX and would like to upgrade to the latest version? If your organization or business has a valid 3CX Phone System Annual License or valid Software Maintenance on a 3CX System Perpetual License, then you can freely upgrade to the latest version of 3CX and take advantage of all the advancements and productivity-enhancing features of 3CX v15.5 SP6. If your 3CX System License has expired or no longer has the capacity or feature set you need, we can upgrade your 3CX System license to meet the current and future needs of your organization.

As with any upgrade, it is recommended to take a backup of the old system before uninstalling it. Once the new version is installed, you can restore from the backup to preserve phone system settings. Please note that license information is part of the backup so it must be excluded if your 3CX License is going to change. Also, note that FQDNs are linked to 3CX Licenses so these will have to be released in the event that you are changing a 3CX License key.
