 From the feature guide of JUNOS 7.4:

% To specify a cflowd server in a sampling configuration, include the
% cflowd statement at the [edit forwarding-options sampling output]
% hierarchy level. You must specify the IP address, port number, and
% cflowd version of the destination cflowd server. Routing Engine-based
% sampling can use only one cflowd version 5 server or one version 8
% server at a time. In contrast, PIC-based sampling allows you to
% specify one cflowd version 5 server and one version 8 server
% simultaneously. However, the two cflowd servers must have different IP
% addresses.

 So, if you don't has AS PIC or similar, you can only have one cflowd
 export destination. With an appropriate service PIC you can have two
 (one for v5 and one for v8). I don't like this because it would be
 nice to have the possibility to export the flows to two different
 servers. If one is having problems, the other one would probably
 still be able to receive and store the data.

 Cheers,
