You can update post offices after you have updated the primary domain and the secondary domain that owns the post offices that you want to update. For information about update issues that you should consider, see Section 14.4, Understanding Domain and Post Office Database Updates by the GroupWise Agents.
To update a post office, you need to install the GroupWise 2012 POA and run it for the post office. The POA uses a new GroupWise 2012 version of the post office dictionary file (gwpo.dc) to update the post office database to version 2012.
IMPORTANT:The MTA for the domain that the post office belongs to must be updated and running before you update any post offices in the domain.
