Another significant survey finding is that mainframe modernization plans are more dynamic than they’ve been in the past due to changing market conditions: 80% of organizations reported that their modernization strategy has shifted in the past year, “indicating widespread re-evaluation and a degree of agility not commonly associated with technology projects of such significant size, scope and complexity,” Kyndryl stated.
Mainframe modernization can take a few forms; enterprise customers can keep data on the mainframe, migrate workloads off, or create a hybrid environment.
Among organizations that said they’ve shifted their modernization approach, 43% are more focused on modernizing directly on the mainframe, and 50% are moving more towards a hybrid strategy, Kyndryl found. Among those that are moving towards a hybrid IT approach, 34% are prioritizing integration with cloud platforms, and 16% are increasing the pace of moving applications off the mainframe. Only one out of 500 respondents reported plans to move entirely off the mainframe.
The reasons for changing their migration strategies vary widely among respondents and include factors such as the success of previous projects, budget shifting to new technologies, and external factors such as geopolitical, macroeconomic and regulatory concerns, Kyndryl stated.
Cost is another motivator: The average cost of modernizing on the mainframe dropped from $9.1 million in 2024 to $7.2 million in 2025, and the ROI on such a move more than doubled, Kyndryl stated.
