If the migration is performed in VMC environments, sometimes OVA upload times out. In this case, you can follow either of the following approaches.

Procedure

1. Ensure that the firewall is open for ESXi host 433 and reachable from migration container. If migration container is unable to reach due to NATed ESXi hosts, deploy migration container on the jumpbox or inside the NATed environment where the host can reach.

   Or

2. Manually upload the template for each of the deployment type to any folder within the same data center with the following VM template name syntax. For example, if the Large and Medium types are used then the VM template name syntax will be:

   VMware-Telco-Cloud-Automation-3.1-22803370-Large

   VMware-Telco-Cloud-Automation-3.1-22803370-Medium
