Today we moved one of our RT from a 4 years old Fujitsu-Siemens RX300 S3 with 2x Intel(R) Xeon(TM) CPU 3.20GHz and 2GB RAM to our VMware ESX Cluster. The VM is configured with 4 CPU and 4GB RAM. With this move we also upgraded the OS from Debian lenny to squeeze. The actual copy job of our 4GB DB took 30 minutes.
I took this opportunity to move our customizations from the local folder into an RT Extension.
