* It is strongly recommended to create a VMware Virtual Disk Development Kit (VDDK) image in a secure registry that is accessible to all clusters. A VDDK image accelerates migration and reduces the risk of a plan failing. If you are not using VDDK and a plan fails, then please retry with VDDK installed. For more information, see xref:../master.adoc#creating-vddk-image_vmware[Creating a VDDK image].

When you migrate from {osp} to the {ocp} cluster that {project-full} is deployed on, the migration allocates persistent volumes without Customized Data Importer (CDI). In these cases, you might need to adjust the file system overhead.

If the configured file system overhead, which has a default value of 10%, is too low, the disk transfer will fail due to lack of space. In such a case, you would want to increase the file system overhead.
The configured file system overhead has a default value of 10%. If that is too low, the disk transfer fails due to lack of space. In this case, increase the file system overhead.

In some cases, however, you might want to decrease the file system overhead to reduce storage consumption.
If you need to reduce storage consumption, decrease the file system overhead.

You can change the file system overhead by changing the value of the `controller_filesystem_overhead` in the `spec` portion of the `forklift-controller` CR, as described in xref:configuring-mtv-operator_mtv[Configuring the MTV Operator].

* If you are migrating more than 10 VMs from an ESXi host in the same migration plan, you must increase the NFC service memory of the host.
* It is strongly recommended to disable hibernation because {project-first} does not support migrating hibernated VMs.
