Migrating Netbox to another AWS account with no downtime

[jeschebach]

Hi folks!
I have a Netbox deployment (web server, databases, vpc endpoint service) in AWS and need to migrate it to another AWS account, with no (or minimal) downtime. There are some clients connecting via VPC endpoint to the service, so I have to keep the endpoint running until they are able to update the new endpoint on their side.

Given these conditions, I believe the most suitable option is to have two Netbox instances sharing the same database, as advised here. However, for my setup it'll be convenient to keep using separate Redis instances on each setup, like:

Redis (account A) 
     |
Netbox (account A) ------ PostgreSQL (account A)
                           |
                           |
Netbox (account B) --------|
     |
Redis (account B)

Would it be recommended for production setting?

Thanks in advance!
