Sounds ok, but I'd actually setup the new vCenter after step2 or 3. This will allow you to configure the new environment (e.g. HA, DRS, EVC, ...) prior to inventory, and power on the VMs on the new hosts.
A quick note about step 2: In addition to the proper zoning, you will also need to present the LUNs to the new hosts from the storage side.
Stop! This is a problem! Why do we have to do this?
Rather, I want to thank you for your practical observation and similar experience.
WWN is already set up in storage and done zonning.
Not a new server, it already exists and is in use with version 5.5
Does it work the same as an iSCSI connection? That is, when installing the new 6.7, the IQN is changed?
I imagine that being an FC connection, similar to SAS, we would not need to do any kind of storage intervention.
So if what you say is true, opt for the migration from 5.5 to 6.5 and then to 6.7, I avoid that kind of problem, right?
