Stop the old instance of ejabberd. 2. Run 'make install' of new ejabberd 2.1.0 to create the new directories. 3. Copy the content of your old directory: /var/lib/ejabberd/db/NODENAME/ to the new location: /var/lib/ejabberd/ so you will have the files like this: /var/lib/ejabberd/acl.DCD ... 4. You can backup the content of those directories and delete them: /var/lib/ejabberd/ebin /var/lib/ejabberd/priv /var/lib/ejabberd/db 5. Now try to start your new ejabberd 2.1.0.
