when using Ant Force.com Migration tool,can newly added picklist values to standard object's standard picklist fields which come out of the box be migrated by just including the standard field ?
Yes you can simply migrate by providing appropriate defination in package XML
<?xml version="1.0" encoding="UTF-8"?> <Package xmlns="http://soap.sforce.com/2006/04/metadata"> <types> <members>Account.Industry</members> <name>CustomField</name> </types> <version>35.0</version> </Package>
The above shows how you will migrate industry picklist field for Account
The example given is out of date now as of API 38. See StandardValueSet.
