Миграция мнезия BD ejabberd v 2.1.5-3 -> 16.09-4

У меня есть oldserver с Debian 6, ejabberd v. 2.1.5-3 с mnesia BD, и мне нужно переместить пользователей и пароли на newserver с Debian 9.6, ejabberd 16.09-4 и mnesia BD. Названия серверов разные. Я делаю ejabberd.dump, ejabberd.backup на oldserver. Когда я пытаюсь на oldserver сделать:

root @ oldserver ejabberdctl export_piefxis / var / lib / ejabberd / 1 /

Problem 'throw {error,exmpp_not_installed}' occurred executing the command.
Stacktrace: [{ejabberd_piefxis,try_start_exmpp,0},
             {ejabberd_piefxis,export_hosts,2},
             {ejabberd_ctl,call_command,3},
             {ejabberd_ctl,try_call_command,3},
             {ejabberd_ctl,process2,3},
             {ejabberd_ctl,process,1},
             {rpc,'-handle_call_call/6-fun-0-',5}]

Я скопировал ejabberd.dump, ejabberd.backup, каталог ejabberd со старого сервера в /var/lib/ejabberd_old/ на новом сервере. В newserver я попробую:

root @ newserver: ejabberdctl load /var/lib/ejabberd/old/ejabberd.dump

Can't load dump in "/var/lib/ejabberd/old/ejabberd.dump" at node ejabberd@Public: open

Что я могу сделать больше для переноса БД в новую версию ejabberd.
