[ESXi 7.0.2 + NSX-T 3.1.3.1] Preparing for migrations of N-VDS to VDS

So I´m reading "Migrate Host Switch to vSphere Distributed Switch"

 

 

 

 

 

 

Prerequisites
[...]
NSX-T is no longer represented as an opaque network after migration. You may need to update your scripts to manage the migrated representation of the NSX-T hosts.

 

 

 

 

 

 

 => Which scripts does this refer to?

So the migration can be done via Web based NSX manager, too. Is there any other documentation available which describes what is actually done?

1. Clicking System => Configuration => Quick Start => Prepare Hosts for Migration from N-VDS to VDS 

2. Creating a new VDS

3. Putting hosts in maintenance modus

4. Magic migration script is running on each host

5. All hosts boot without problems

6. Everyone is happy

 

- What can actually be go wrong?

- How can I actually roll back each host to N-VDS?

- Is the NSX manager´s configuration touched?

- How to roll back the NSX manager?

- Is there any "Backup & Restore" documentation available for that migration process?

- How long does the migration process take for one host? (e.g. Upgrading one of our hosts from NSX-T 3.1 to NSX-T 3.1.3.1 took roughly 15 minutes)

Hi Chris, 

 

I maybe able to answer some of the questions later; Quick question Did you upgrade your VDS to 7 ?

Hi Chris 

 

Thanks for your reply! 

If you upgraded to VDS 7, and done please mark it as resolved.

If you will, then make sure that your ESXi hosts are all vSphere 7


If not resolved yet, then feel free to tell me more : ))

Well we hit the Upgrade-Button on ESXi for the vDS 6.6 switch, i.e. this one is now version 7.0.2. I´m asking for a migration process of N-VDS to VDS 7.
