VCD 5.5 + VCNS 5.5 upgrade or migrate

[yak01]

Hi,

We have vsphere 5.5 enviroment with VCD and vShield manager, we need to upgrade to vsphere 6.5, VCD 8.2 and NSX 6.3.

What will be the recommended​ way?

1. Upgrade the existing environment step by step.

2. Build a clean environment and migrate catalog, vApps templates etc. Is this a valid option?

This is one Cell environment.

Thanks.

Confirm the upgrade is fully supported as per VMware Product Interoperability ->VMware Product Interoperability Matrices  . It looks supported as per my check

> Take backup&snapshot of VCD,VC and VCNS

> Upgrade underlying vsphere infrastructure followed by VCNS to NSX

Upgrading VMware vCNS 5.5.x to NSX 6.2.x (2144620) | VMware KB

NSX 6 Documentation Center

> Register NSX with New VC

> Upgrade VCD (Take a back-up of VCD prior to this stage- In case of upgrade failure you can simply revert to working state)

> Start the cell service after Upgrade and check VC/NSX connectivity

Hope there is no cert/fqdn/ip change ?
