I want to migrate my OS via "vcenter converter standalone" to my ESXi 5.5. I installed it locally and select my partition for convert and choose my ESXi host. It show me my VMs that are on my ESXi. I created a Test vm for this convert and select it. in the next step, it ask me about storage and selected the storage that want my VM put there but my questions is that it remove all storage? or just remove all VMs that exist on a storage that I selected? or none? I have other VMs on storage that I selected and I don't like remove them.
That's just the selection of target/destination storage to put the converted VM on. It does not delete/remove anything. Just give the converted machine an approbiate name and run the conversion job.
This tutorial of vCenter converter is pretty detailed: VMware P2V Migration: Importing Virtual Machines into VMware ESXi Pt 1 and VMware V2V Migration: Importing Virtual Machines into VMware ESXi Pt 2
