No steps are required to migrate 2.1 ESD #3 applications to version 2.2 SP02; however, you may need to perform some migration steps to take advantage of new features.
If you are migrating from a version earlier than 2.1 ESD #3, see Release Bulletin 2.1 ESD #3 on Product Documentation, the Required Changes for Object API Applications section for your platform: http://infocenter.sybase.com/help/topic/com.sybase.infocenter.dc00835.0213/doc/html/aro1360961280513.html.
