This impact includes gains in productivity, operational efficiency, and new capabilities to interact with customers.<\/p>\n\n\n\n<p>These figures confirm that technological modernization in banking is a decisive factor. However, day-to-day operations do not always evolve at the same pace.<\/p>\n\n\n\n<p><strong>In many institutions, legacy systems such as AS400, iSeries, or IBM i still sustain daily operations. <\/strong><\/p>\n\n\n\n<p>And while their reliability is unquestionable, they also present serious limitations when it comes to integrating new technologies.<\/p>\n\n\n\n<p><strong>Understanding what they are and how they work is the first step toward modernizing them without replacing them.<\/strong><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_%E2%80%9CLegacy_Systems%E2%80%9D_Mean_in_the_Banking_Context\"><\/span>What \u201cLegacy Systems\u201d Mean in the Banking Context<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Legacy systems are inherited technology platforms, developed decades ago, that still support critical processes in many organizations. In banking, the most common ones belong to the IBM ecosystem: AS400, iSeries, and the IBM i operating system.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_Did_These_Systems_Evolve\"><\/span>How Did These Systems Evolve?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<ul>\n<li>AS400 was launched by IBM in 1988 as a robust and reliable midrange system.<\/li>\n\n\n\n<li>In the 2000s, it evolved into iSeries, with improvements in performance and connectivity.<\/li>\n\n\n\n<li>Later, IBM consolidated this line under the name IBM i, which today runs on Power Systems servers.<\/li>\n<\/ul>\n\n\n\n<p>Although AS400 and iSeries no longer exist as active products, many institutions continue to operate adapted versions.

They require specific commands from terminals such as 5250 or 3270, which limits day-to-day use to specialized technical roles.<\/p>\n\n\n\n<p>Their architecture wasn\u2019t originally designed to integrate with APIs, automated flows, or artificial intelligence models.
