You cannot use an inactivated commercial license to replace an active license key. However, inactivated commercial keys can be used to replace a trial license. Simply put, only trial keys are replaceable.

3CX Trial keys are now 8SC Professional keys rather than 4SC Professional. They can still be upgraded to Proof of concept keys (Minimum 16SC). Trial keys are now only valid for 30 days. Existing keys are not affected by this change.
4SC keys can no longer be hosted by 3CX. Existing 4SC keys hosted by 3CX can be renewed in the usual way and not affected by this change. However, if an existing 4SC key hosted by 3CX expires, this key will need to be upgraded to 8SC to recover the hosting.
