My client has four Netware 6.5 SP6 servers with 500 user licenses. They are looking to migrate to OES2 on the Linux kernel. What licenses do they need to purchase for this migration. I ask the question because Netware 6.5 SP7 is OES2. They will be upgrading to SP7 in a few weeks. The do not have upgrade protection. Also, can I install a OES2 server into this network without issue. Eventually all Netware servers will be migrated.
