Migration from VMware 5.5 to 6.5

Hi,

are the steps to migrate from 5.5 to 6.5 with non-stop clustering?

Only with HA, without DRS.

It is?

1 - Install new vCenter 6.5

2 - Create datacenter;

3 - Create cluster;

4 - Add host A in version 5.5 in the vCenter 6.5 cluster;

5 - Add host B in version 5.5 in the vCenter 6.5 cluster;

6 - Install Update Manager;

7 - Import ISO to Update Manager;

8 - Migrates servers from host A to host B;

9 - Put host A on maintenance;

10 - Apply new version via Update Manager on host A;

11 - Remove host A from maintenance;

11 - Migrate servers from host B to host A already with the new version;

12 - Place host B in maintenance;

13 - Apply new version via Update Manager on host B;

14 - Remove host B from maintenance;

15 - Balancing servers between hosts.

Thank you.
