No. If you use 'upsdrvctl' to start the driver, this will be handled
automatically. What you're seeing now either means that you don't use
'upsdrvctl' to startup the driver, or you're still using some of the
binaries from nut-2.0.3. Note that you always need to upgrade all
binaries when installing a newer version. Usually the communication
between server and clients will not be affected, but there can be
(incompatible) changes between drivers and server.

Best regards, Arjen
