migration issue from 11.0 jail to 11.2

[ykhodo]

I ran the migration script for a non-plugin jail. When I try to start or upgrade the migrated jail, I see the following traceback. Any ideas?

```
Error: concurrent.futures.process._RemoteTraceback:

The above exception was the direct cause of the following exception:

Have you tried googling for that issue? There are many threads on here that detail problems with VNET. Most likely you don't have the interface set correctly. Honestly a lot of people have just created new jails from scratch and saved a lot of time. If you have data from the old jail you can usually copy it out and put it in the new jail before starting it up.

Also please post your full specs (hardware and software).

When I migrated from old warden jails to iocage, I chose to create new iocage jails and then configure them as required. A little more work than just running a script, but it gave me the opportunity to make certain everything for the new jails was configured correctly. I don't like blindly running scripts because, when they fail, it is difficult to figure out why.

I have not had difficulty with VNET on any jails I created with iocage. For the jails that don't migrate properly with the script, you might just try recreating them. There are so many dependencies between OS components, python versions and other utilities, that sometimes it is better to just start fresh - especially if the jail you are migrating from is a very old jail.
