We have several servers with ZCS Network Edition 6.0.9 ( Release 6.0.9_GA_2686.RHEL5_20101115224226 CentOS5 NETWORK edition.) running on Centos 5.8 i386 (2.6.18-308.1.1.el5 #1 SMP Wed Mar 7 04:17:30 EST 2012 i686 i686 i386 GNU/Linux )
Could anybody tell me what we need to upgrade these servers to newest version (maybe 7.2.0?). Do I need to find my license keys? How can I download the new version?
