8 Project Overview The Arizona Department of Revenue is in the process of converting its legacy Oracle based Tax Accounting System (TAS) to a new platform. The new application, STARS, is being developed to meet the changing needs of the department and taxpayers.

" Support analysis and implementation of decommissioning activities for legacy tax types as they are migrated to the STARS system.
" Review and analyze existing COBOL programs, batch jobs, and system workflows related to tax processing functions.
" Implement decommissioning logic and updates required to disable further processing of migrated tax types within legacy TAS systems.
" Validate and test batch processing shutdown procedures and ensure system stability after legacy components are disabled.
" Collaborate with database developers and technical architects to understand dependencies between COBOL modules and Oracle database components.
" Support system regression testing activities to verify that legacy processing changes do not impact remaining operational tax types.
" Assist with documentation of legacy system architecture, processing logic, and decommissioning procedures.
" Participate in defect analysis and resolution related to legacy processing logic and batch execution failures.
" Support system transition activities by ensuring proper documentation and validation of legacy system impact following tax type migration.
