KB29: DIFFERENT SECURITY OR OFFLOAD SETTINGS
This is a migration compatibility error message and indicates that the source and destination servers have different security or offload settings configured on the virtual switch or portgroup that the virtual machine is connected to. The security and offload settings between virtual switches need to be the same to ensure that the functionality of the virtual machines is not affected upon migration
To work around the issue,Check the properties of the virtual switch and/or portgroups between the source and destination servers. Ensure there are no differences between the settings on the Security tab, and the Traffic Shaping tab between the hosts, as explained in the following vmware knowledge base article.
