PostgreSQL version 8.3 was used in all GECAMed installations prior to 1.2.00. Starting with version 1.2.00 GECAMed comes equipped with PostgreSQL 9.1, because versions inferior to 9.0 are not compatible with Mac OS X Lion (10.7.x) and higher. You must must therefore be very careful when upgrading your Mac OS to 10.7 or higher, if you're already runnig a GECAMed server with PostgreSQL older than 9.0.
A Mac OS X 6 → 7 upgrade (Snowleopard to Lion) is possible, but You need to upgrade your PostgreSQL first. To do so we suggest one of the following two methods.
Right now we do not recommend to upgrade from Mac OS 10.6 to 10.7 if you have a GECAMed installation older than version 1.2.xx running on it, because we can not guarantee that Mac OS 10.7 runs a PostgreSQL prior to version 9. However, you can migrate Postgress 8.3 to 9.1 still being on Mac OS 10.6, and then upgraqde to Mac OS 10.7.
We propose two options how to do that, and both will require to export and re-import the database at one tme or another. So do this only if you feel comfortable with backuping and restoring PostgreSQL databases. In case you don't please referr to our support comany page at http://www.gecamed.lu/support to get professional help.
Nowyou can update your Mac OS X from 10.6 to 10.7.
This will also install a new Java version. Therefore the java version fix script has as also to be applied (see Fix the Java version used by the JBoss).
