If your old ejabberd was running in an Erlang node with name "ejabberd@machine1", and your new ejabberd runs in an Erlang node with name "ejabberd@machine2".</p> <p>For example, when I start ejabberd I see in ejabberd.log:</p> <pre>=PROGRESS REPORT==== 22-Jun-2009::16:33:52 === application: ejabberd started_at: ejabberd@localhost</pre><p> Solution. Find what is the Erlang node name of your old ejabberd. If it wasn't the same than in the new machine, then edit ejabberdctl.cfg in your new machine, and put the old name. Something like:</p> <pre>ERLANG_NODE=ejabberd@machine1</pre> Mon, 22 Jun 2009 20:43:38 +0000 mfoss comment 54384 at https://www.ejabberd.im
