Migration back from Esxi4 to Server2

It looks like my server can't handle this esxi anymore.
All of the virtual machines slow down for weeks.
So, I've been trying to do migration for 3 days.
And Today I've found a way to do it easily.

First you gotta have a VMware vCenter Converter Standalone Product
you can download it for free at vmware.com

Now you got installed, It will be like this.

Then just select Convert Machine on the left side of the panel.
It will ask you whether type you want to convert. I choose the first one
"VMware Infrastructure virtual machine"
Don't forget to enter your esxi's address and username with password.

Then choose the virtual machine you'd like to convert.

 Wait until it completed converting. Then it's all done!!
