Migrate iRedMail data to new system Modoboa -- 2

My company originally used iRedMail, now we want to migrate the data to Modoboa. Please download iRedMail 0.8.7 and try to migrate it. Process: I will open 2 VPS machines and provide a domain. Please create Modoboa docker on one of them, and confirm that you can send and receive mail. Then create iRedMail on the other one. About the domain, please set up a DNS server that you can control (such as cloudflare). I will set the DNS server to the location you specify so that you can fully control it. Please sign up accounts on iRedMail. Confirm that you have established multiple accounts, all of them can send and receive emails. It could migrate to the docker of another Modoboa and can send and receive messages without any problem. * Please provide the script of Modoboa dockerize * Please provide the script to transfer iRedMail to Modoboa docker, and it could be used in different domains * Please provide proof of test success and process description * After the script of the first 2 points is provided, please provide assistance when I actually want to migrate
