Integrating legacy systems with new technology presents multiple challenges, including compatibility issues, data migration difficulties, and high costs. Legacy systems may utilize outdated programming languages or proprietary databases that resist interoperability with modern platforms. Additionally, staff training is necessary to ensure that personnel can effectively work with new systems. There is also a risk of disrupting existing business operations during the integration process, which can affect overall productivity and lead to potential loss of data accuracy. Thus, careful planning and a systematic approach are vital for a successful transition.
