Downgrade 3CX license from 16 to 8 simultaneous calls without reinstalling?

[DESIMO]

Hello, good afternoon.

We currently have a 3CX PBX installed on our own server, working correctly, with a license for 16 simultaneous calls.

We need to downgrade/change that license to 8 simultaneous calls.

I would like to know if this change can be done directly on the same installation, without reinstalling the whole PBX, or if a fresh installation is required.

I would also like to know if it is possible to create a full backup of the current configuration and restore it later if we need to reinstall or change the license.

The PBX has approximately 40 extensions configured, SIP trunks, inbound/outbound rules, ring groups and other settings, so we want to avoid losing the current configuration.

My questions are:

1. Can we change from 16 simultaneous calls to 8 simultaneous calls without reinstalling 3CX?
2. Does the license change update automatically on the PBX?
3. Is it necessary to change the license key or only renew/modify the current license?
4. Can I create a full backup and restore it on another installation if needed?
5. Does the backup keep extensions, trunks, rules, recordings, IVR, groups and general settings?

Thank you for your help.

The question is simple: can I go from 16 to 8 without resetting everything?

And I have another problem: it won't let me post in the Spanish forum, and it won't let me post here or in several other places either. I have a 16-channel license, and I don't understand why. I've had the same email address and everything for a long time.

Is your forum email the same as the license email?

You need to ask 3CX directly about the license.

@DESIMO - you have a 4SC PRO license, not a 16. 4SC PRO means you only have access to this forum. Note there is no included technical support on any license, this has to be purchased separately and its not available for a 4Sc PRO license.

Tengo otra cuenta con 16 SC y ni siquiera me deja publicar, usé esta otra de otro cliente.
