Seeking confirmation about pro to basic downgrade affecting FDQN

[Geoint]

When downgrading a Pro 3CX on-prem instance to basic, will my custom FDQN continue to work? (I plan on switching from using a custom FDQN to a 3CX provided one) According to https://www.3cx.com/community/threads/coming-soon-downgrading-to-the-3cx-basic-edition.136144/, the answer is yes, but you shouldn't, but 3CX promises they won't check, but it's not a feature of basic. From this information, I am not confident in downgrading my current instance, would it just be better to forgo my current instance and set up a new one with a new licence? It seems I am somewhat required to do that anyway, as there is not easy way of switching domains as far as I am aware.

@Geoint Custom FQDN is not supported with Basic editions. You can review the each edition features here https://www.3cx.com/ordering/pricing/features/.
When changing from custom FQDN to 3CX FQDN, a complete reinstallation and rebuild of your system is required either you use the same license or obtain a new one.
