Migration to 3CX Cloud from Self-Hosted

[crum70]

We will be migrating from an on-premises version of 3CX to the hosted version. We think we are pretty clear on the migration process based upon

https://www.3cx.com/docs/switch-hosted-pbx/.

We are not clear however on how to change the FQDN. Our FQDN is currently pointing at an IP address associated with the on-premises instance. All users are using the CTX soft phones on there cell phones. We are assuming we need to change where the FQDN points to avoid having to reconfigure all the CTX soft phones. We don't know how we figure what change we should make.

Thanks for any help,

John

Hi, I can notice that you are using your own domain. To install with the 3CX Hosted you must use a 3CX FQDN. Since that installation is still running v18 my advise would be taking a backup without the license key and fqdn, delete the current machine, release the fqdn in the license key from the portal using the registered email in the license. Once done, deploy a new machine in your location where you will be able to set a 3CX FQDN, after that make sure you have followed all the checklist in this guide, review that as provisioning interface you are using the new one pointing to the 3CX FQDN and take a new backup including the 3cx fqdn, license and system owner to migrate with hosted by 3cx.

Have a good day!

Hi Alejandro,

Unfortunately, anything involving changing or upgrading the on-premises instance is not a realistic option. We have an existing backup with license key and fqdn. We have admin rights to the on-premisis instance on the CTX level but we do not have access to the hardware or underlying system/vm/etc. It might be possible to get a different backup but it would be simpler not to.

Can you clarify a few things...

1. Can we upload a v18 backup to the CSX cloud?
2. If we upload a v18 backup with the fqdn from our own domain, can we "fix" the fqdn after the upload or set it to a 3CX domain? Would it upload with "3cx.ourfirm.com", we change it in the hosted version to "some value 3cx gives us"?
3. Could we setup the hosted 3CX and restore a backup of some sort to just get the users and call groups?

What we are trying to accomplish is

1. Restore the system without touching the users phones with existing call groups, etc.
2. Restore the system with existing call groups but have to touch the users phones to change settings
3. (last resort) recreate system from scratch.

Any help or suggestions would be greatly appreciated.

Thanks,

John

Hi, if you upload the backup with the current fqdn it will install the system with the same domain, the FQDN is set only during the deployment process and not after the pbx is installed. That being said if you can't do the procedure shared in my previous note, then you could try to export the users in a csv file, export the sip trunks and contacts, then delete that machine, release the fqdn and install it from scratch....
