I'm about to embark on a project to virtualise an existing system that consists of 5 independent systems, and seeking some advice on migration paths.
I intend to build the individual virtual machines using VMWare server, and then copy them to the production server on ESX server or appropriate platform.
My questions are two:
1. are there any significant barriers to migrate from VMWare Server ('free' version) to a production system with ESX or other VMware product?
2. what should I be considering now if I expect to improve availability by upgrading to a dual server platform with VMWare virtualcentre for automated fail-over etc?
Thanks in advance for any comments and suggestions,
