you can move mnesia through text dump with some work on this text to change nodename.
you must read ejabberd manual in part of ejabberdctl.cfg.

|Hi all.
|We have an installation of an ejabberd 2.1.6 on a machine and we're
|upgrading servers (phisical different server with different
|We tried the procedure described here (https://git.process-one.net/ejabberd/mainline/blobs/raw/v2.1.11/doc/guide.html#htoc79)
|for mnesia migration, with no success.
|When issuing the mnesia_change_nodename command we always end up with
|the following error:
|Error: {"Backup traversal failed",enoent}
|We couldn't make this work neither using the same binaries copied
|from the old machine to the new (both are ubuntu linux 64bit, the new
|one has a newer release - 12.04LTS the old one IIRC was a 10.04), nor
|installing from scratch newer ejabberd versions (2.1.8 and 2.1.11).
|No clusters are involved.
|In the end we just copied the old installation to the new machine and
|started it. It works, but we have to kill it manually as ejabberdctl
|gives a "nodedown" message when stopping the instance.
|Any idea on how we could get rid of this problem?
