migrate FTP server (IIS FTP) from 2012 to 2019

Hi @Suy Peang ,

1. The IIS Easy Migration Tool (IEMT) helps with the migration from one Microsoft IIS server to another. It helps to transfer web sites, Windows users, Windows user groups, FTP accounts, virtual directories, application pools, SSL certificates, Web/FTP folders structure and also assign NTFS folders permissions. You can try using IIS Easy Migration Tool. This is the IIS Easy Migration Tool quick start guide
2. Besides, Web deploy should also work for FTP site. The migration process of Web Deploy can actually be regarded as a synchronization process, synchronizing the websites on the source server to the target server; or synchronizing the websites on the source server to a package, and then synchronizing the package to the target server. If you want to use Web deploy, you can download it from this link. And this blog can give you some reference.
3. Also, there is another way to use CopyRight2's IIS Migration Add-On to migrate Microsoft IIS FTP sites including virtual directories, settings & accounts between servers. There is a YouTube video detailing how to migrate all FTP related data and users, and this is a video of installing CopyRight2. Of course, this method uses third-party tools, I recommend you to use the first two methods.
