The VM in question is a mail server (running MDaemon) which is in production so uptime is an issue. I belive the best approach to resolve this issue is by cloning the VM via the Command Line using vmkfstools. I have a VM which has mulitple Snapshots which have failed to be consolidated via the snapshot manager.Follow along with nine hands-on demos, as Rick shows how to create VMs and vApps, install VMware Tools, clone VMs, and speed up your workflow with VM templates and snapshots.When virtualizing Windows Server 2012 on vSphere, the VM-GenerationID is included as part of the virtual machine’s VMX file in the attribute vm.genid. The VM-GenerationID is a unique identifier exposed to the virtual machine by the hypervisor that helps to prevent issues with domain controller snapshots, cloning, etc.CL1 is a ESX 3.5 environment where as CL2 is 4.0. We used SVmotion to move this VM as the other big VMs. The final challenge is moving this FAT VM to CLUSTER2(CL2). We used the SV motion and moved all the VMs to the new NetApp LUNs which are assigned to the server.VMware ESXi (formerly ESX) is an enterprise-class, type-1 hypervisor developed by VMware for deploying and serving virtual computers.As a type-1 hypervisor, ESXi is not a software application that is installed on an operating system (OS) instead, it includes and integrates vital OS components, such as a kernel.So think twice when you press the “delete all.

This means that if you want to delete all snapshots at once you will need around 130GB of free diskspace. In other words: Snapshot 3 is merged into Snapshot 2, Snapshot 2 is merged into Snapshot 1, Snapshot 1 is merged into the original flat.vmdk and afterwards all snapshot files are deleted.

Convert vmdk to vmx files
