I sure hope they have worked out a better mechanism now than they did in the past with regards to beta version upgrades going forward. In previous times gone by you had to completely destroy and rebuild your entire setup every time a new build came out, as they did not support upgrades from beta to beta, nor ugprades from beta to final. The installer enforced this so technically it wasn't (easily) possible to do nor can you upgrade by saving the config and re-importing it.

No sane person is going to want to recreate their entire lab and rebuild vCentre (with dvSwitches etc) every few weeks for each new build. People who are *that* into it have paid jobs to do and won't waste hours and hours of time rebuilding their environment to help VMware for free (it's also as boring as all get-out to do). And it's certainly questionable if people will want to ever put a real workload on such a temporary setup.

I have never figured out if VMware understand the practicalities of this but this is just a token gesture to indicate they are "community friendly", or if they genuinely believe people are prepared to spend their waking hours testing their software for free.
