In Winter '16, Salesforce rolled out the Lightning Experience. This can be optionally enabled for particular profiles. Initially this is not available for orgs that are using person accounts. Sandboxes for those orgs may see an option in setup to "Enable Lightning Experience" but that option is not available in production. When that option is available, a number of built-in user profiles are given a LightningExperienceUser permission. If you attempt to deploy those profiles to production however, the deployment will fail and give an "Error: Unknown user permission: LightningExperienceUser" error.
How can this error be resolved?
