 +==== Migration from atmail archivevault ====
  
 +
 +This document provides a description on how to migrate from atmail'​s archivevault to piler.
 +
 +**Before we begin**
 +
 +Before we begin, install piler. Decide if you want to install piler to the same (perhaps virtual) machine where atmail'​s archivevault is located, or you want another host.
 +
 +When piler is installed, then change the settings of your mail server to pass a copy to piler, and not to archivevault any more.
 +
 +**Importing emails from archivevault**
 +
 +Atmail archivevault stores emails under /​usr/​local/​archivevault/​messages in bzip2 compressed files. Even though archivevault doesn'​t offer an export tool, the process is pretty straightforward. Atmail does not use deduplication,​ so each bz2 file represents an email.
 +
 +Run the following commands to import emails:
 +
 +<​code>​
 +cd /tmp
 +
 +for i in `find /​usr/​local/​archivevault/​messages -name \*.bz2`; do bzip2 -dc | pilerimport -e - ; done
 +</​code>​
 +
 +When the process is done, you have your emails in piler. If you decided to use another host for piler, then you should either NFS mount archivevault'​s directory to the piler host or copy the emails with rsync or scp, etc to the piler host before importing.
