Compatibility: It is strongly recommended that you test the upgrade on a development or test environment first. Please backup your files and perform the necessary tests after the upgrade. If you are upgrading from v3, please note that there have been security hardening changes since v4 so please refer to v4 Compatibility. Licensing: For the Enterprise Edition, upgrades between major versions (e.g. v4 to v5) requires re-activation with a new license, so users with an active Enterprise Software Subscription are required to request for a new license. |
