This is a little, yet relevant, difference between Syncplify.me Server! v3 and v4. Version 3’s license codes were composed of 3 chunks of 4 digits each (ex: 1234-1234-1234) while the new v4 features license codes composed of 4 chunks of 4 digits each (ex: 1234-1234-1234-1234).
This means that v3 licenses are not compatible with v4. If you are an existing customer with an active support/maintenance and upgrade protection subscription, you will still need to contact us (before upgrading from v3 to v4) in order to request your new v4 license code. As usual, all v3 customers with an active subscription will be entitled to a FREE upgrade to v4.
