I migrated my physical Windows Server 2003 from native to virtual using the excellent VMWare Converter 4.  No issues at all.  Just remember to stop any important services before starting the conversion, i.e.: Exchange and remember to configure the new VMWare network device in the guest after the conversion is complete.  Not much else to say when everything works just perfectly!

Migrating the Windows server and Linux server to ESXi were both a breeze.  I’ve found two problems so far:

1) My blog (this site) seems to lock-up every so often (once or twice a day) requiring Apache to be restarted.  Not sure if this has anything to do with VMWare since everything else on the system is fine and other web sites are served fine…it’s just my blog that is stuck.  Seems that Apache starts eating up a whole bunch of virtual memory as well so it may be some wierd deadlock issue.  Of course right after moving the Linux server to ESXi, I updated a few Wordpress plug-ins right away so it’s a bit hard to pin-point the problem.  I’ll have to investigate a little more and find the solution.  Might have to update to Wordpress 2.7.1 if it turns out to be a compatibility issue.

2) When I was going to put the server in my basement corner “computer shelf”, turns out the case didn’t quite fit.  The previous Dell computer case is a bit smaller and fit in just fine.  I might need to make the shelf a slight bit more spacious with a hammer and chisel…

Well, aside from the blog/lockup problem, this has probably been the easiest server upgrade ever.  Usually when I change around server hardware, I have to re-install the OS from scratch, reconfigure everything, run both systems in parallel for a bit, blah blah blah, total pain in the butt.  Virtualizing the environment with ESXi has been clean, fast, easy AND I still have the capacity to add more virtual machines to the server for OS upgrades, testing and whatever else I can think of.

ESXi rocks!
