According to the guides My upgrade plan are given beloww (and, please, tell me if this is wrong):
1. View Connection Server 4.6 -> 5 [ same server upgrade ]
2. View Composer 2.6 (View 4.6) -> 2.7 (View 5) [ same server upgrade ]
3. View Center (and sub-items like Update Manager) 4.1 U1 -> 5 [ same server upgrade ]
4. ESXi 4.1 U1 -> 5 [ probably vmotion VMs / fresh install ]
