Erdas Apollo 2010 Change server name

Recently I changed the computer name that hosts Erdas Apollo 2010, and services stop working.
So I basically did
1. search and replace on the *.xml, *.fac, *.txt that refer to old-computer-name and replace them with new-computer-name
2. search and replace on apollo-client.war
Because this is effectively a zip file, I had to unzip it, did search and replace, zip it again, and place it in \APOLLO2010\jboss\server\default\deploy directory
