On the passagepoint server machine
1) Locate and stop the passagepoint service.
2) Locate the PPGlobal folder and backup the entire "config" folder.
3) On the Database side, see steps below if using postgresql. (If running MS SQL server or Oracle, please consult your DBA)
to determine if you're running PostgreSQL, open the sqlcontext.xml file, and if it says "org.postgresql.Driver, passagepoint is using postgreSQL
