Not tested but you can probably do something like this in the target server:
doveadm backup -u victim -R ssh sudouser@old-server "sudo doveadm dsync-server -o mail_location=sdbox:/location-to-your-sdbox/ -u victim"
just leave ALT storage path from the setting.
I'll have to test this... but my initial guess would be that doveadm would then think the mails has disappeared. Would it then copy the index metadata for those mails to the target host anyway?
Hmm. That is true. It will probably not work after all then.
Now I'm out of ideas how to do this efficiently.
