old host copy:

1.remove all snapshots from vm

2.from old host to new host copy...

vm.vmdk

vm.vmsd

vm.vmx

vm.vmxf

3. take a snapshot of old vm (arrange that noone make updates to website during this time. all this data will be lost.)

4. from old to new copy vm-flat.vmdk (this will take the longest)

5. on new host add vm.vmx to inventory in datastore1 repository.

6. change new vm network card to "host only" network( "host only" is virtual switch with no nic.)

7.start up new vm.

8.select I_moved uuid from vsphere client.

9.install new vmware tools

10.check to see if vm is working as it should.

11.shutdown and upgrade vm hardware.

12. check again to make sure everything is working in vm.

13.shutdown old vm.

14.change New vm network seting to correct virtual switch.( I did this with vm still running to avoid the startup time)

Voila! Only about 30 seconds of downtime. This won't work if you need the delta from the old vm. all I lost was 90 minutes of weblogs.

This might seem kind of obvious to those with more experience but perhaps there are others like me that could use this list.
