The typical problems encountered by companies that use legacy systems are:

• batch applications takes more time for processing
• response time is poor in online applications
• high lead time for MIS reports
• new application development takes longer time
• high cost of software maintenance
• redundant reports, programs, screens and processes
• source code of legacy systems may not be available or partly available with non-standard and lack documentation
• due to decentralized development many systems are standalone leading to inconsistent data definitions, data duplication and multiple databases without proper linkages
• difficult to maintain the existing applications due to lack of personnel with legacy technologies

To overcome the above problems associated with legacy systems, companies often take external help from IT experts specializing in legacy management.
