UserGate update and removal
Before you install a new UserGate version it is recommended to remove the earlier one and save the server settings file (config.cfg file, located in the UserGate directory; hereinafter %UserGate%) and the statistics file (log.mdb file, also in the %UserGate% directory).
UserGate Server v.5 supports the UserGate v.4
settings format. A settings format conversion will be done after
the Server’s initial start. Format compatibility earlier than v.4
is not supported.
