Question
Is a new license key required when upgrading from DPX 4.4.4 to DPX 4.5.0?
Answer
No, a new license is not required. In order to upgrade your DPX environment from version 4.4 to 4.5 you do not need to obtain a new license file.
Browse to the .ssbe_key file already located in the .../DPX/ installation directory on the master server during the upgrade to DPX 4.5.
