Moving messages between servers with different configurations

I wanted to move messages from a mbox mailbox on server A to mdbox on server B. I thought I could do this by connecting to the remote server with "doveadm move -S x.x.x.x:x -u testuser Archive/2017 mailbox INBOX/test" but I guess this will only allow and move messages internally on server B? Should I use dsync, or is there another way to move the messages?
