Hello All, Can anyone please clarify one point for me.? I want to upgrade current base server which is an 6.0.2.1.0 version .. to the latest versions, in any way will this cause any issues or incompatibilities with the my remaining receiver servers, which will still be on v5.6.x.?Cheers....NaveenTeamSite 6.5.0 , Windows server 2003.
