v18 to v20 upgrade

  1. Notes and questions from my v18 to v20 upgrade

    Notes: Check if you can access your SBC to reboot before you start the upgrade. Make a full backup AND a smaller one with only licensing and FQDN info. I think the max upload for backup is 4 gig if you use the 3cx web install. If you are following this guide...

  2. Question about testing v18 to v20 On-Prem

    Hey All, I established a 60-day trial to test the upgrade to v20 for our on-prem v18 system on Windows. I am using a temp virtual machine for testing, which is off-site from the production system. This is not a clone of the production 3CX VM, it is a fresh install of Windows Server 2022. I took...

  3. V20: Timeline for Restoration of V18 Features

    Hello 3CX Team and happy 2025!! Now that v18 is EOS, is there an estimated timeline for the restoration of the below v18 features not yet available in V20?

  4. V20 Going Forward - Best Practice for Staging Environment to Test Updated Versions

    Hello, Our current protocol for updating 3CX versions is to bring up a staging system with it's own license and FQDN to which we restore a backup of the target production system minus the license and FQDN. We then register test deskphones, apps, etc. and fully QA. This allows us to create a...

    Hi, Is it possible to upgrade our NFR phone system from v18 to v20? We are getting an error "Your 3CX Debian OS failed to update ID:10012" We are using the 3CX hosted, with a 3CX Standard (18.0) 2 SC NFR license. Not sure if that's the issue, or how to obtain a new NFR license for V20 if so...

  6. Create new V18 Instance for V20 Upgrade Test

    Hi, I want to test the upgrade of my V18 3CX (hosted) instance to V20, but would prefer not to do this on my live instance.

  7. Backup v18 Windows, Restore v20 Linux Without activation

    As the title of the post states, I am currently running v18 pro on Windows and I'm wanting to restore my backup to a newly deployed v20 Linux. I know I can do that because I did it on one of our small single rooftop installations (7-8 users) over the weekend. My question is can I do that...

  8. 3CX HOSTED V18 Build 9 to V20

    Looking to be pointed in the right direction from folks who read / respond to the 3CX Forums: I have a barebones simple install of 3CX which is HOSTED by 3CX and have made myself the system owner. I have no elaborate call trees or call flows, just several extensions tied to softphones, VoIP...
