Solved Can't restore v18.5 backup to a v20

[miradmin]

Hi,

I waited a bit long to update my 3CX on premise, currently version 18.5,
My licence key expired, and i can no longer update or validate the renewal of my key.

Support told me to do a fresh v20 install and upload my backup, but the backup failed because it does not contain a system owner.
If i'm not mistaken System owners profiles were created in 18.8. I tried to make an extension with every rights on the console, but the same message displayed, no system owner.

Is there any solution other than doing a fresh install and doing reprovisioning everything? This represent days of work.

Thank you for your help.

Install v18 u9 and restore your backup. Set system owner und upgrade your system to v20.

@miradmin Hi there.

You can go to your portal.3cx.com
select your license key and then next to it, you will see Install:



After you follow to Self hosted / On premise :



and then you will select the OS, and if Linux you will choose which ISO to download, as the link will be there:
