These are vCenter advanced settings (set the value to false);
Administration --> vCenter Server Settings --> Advanced Settings
Here is the sledgehammer approach;
config.migrate.test.CpuCompatibleWithHost
- With this parameter set, all CPU-related compatibility testing throughout the vCenter Server is disabled. If you have ESX/ESXi hosts on different hardware, the CPU compatibility won't be tested, and this could have serious knock-on impacts to the VMs.
But you may want to look at using one of the following instead;
config.migrate.test.CpuCompatibleMonitorSupport
- With this parameter set, then "product version does not support features" errors will be suppressed, but other CPU compatibility errors will still be tested for.
config.migrate.test.CpuCompatibleError
- With this parameter set, then CPU compatibility warnings will still be displayed in the migrate wizard, but they won't block the migration.
