Is modernizing your software applications to the cloud a topic of discussion in your organization? Though a move to the cloud may not be the immediate next step in your organization’s IT strategy, it is likely that such a migration will eventually be critical to long-term success. If you’re contemplating (or already planning on) a move to the cloud and need to modernize your applications, then you need to be prepared.

With hundreds of large-scale modernizations under our belt, the TSRI team has seen the good, the bad, and the ugly. While no modernization effort is without its bumps, there are things you can do to pave an easier path. We’ve developed a checklist to give you a head start on your modernization journey to ensure success from the beginning!




Discovery on your existing mainframe 

Conduct a technical assessment to help understand your existing systems to set a baseline for a transformation.



Existing languages (primary sub-languages)

Lines of code and comments

Readability and completeness of application documentation

Blackbox libraries



Database platform(s) & versions(s)

Database Metrics (Size, Tables, Columns, etc.)

Database type(s), e.g., flat file, relational, mid-range, etc.

Connection nodes to application codebase & other services


SCREEN (user interface)

Types (graphical or text-based)

Interoperability between applications


Feature assessment


Licensing agreements

Tool feasibility

Assessment of needs


MIPS consumption

Transactions & transaction volumes

Third-party tools & services

Customized tools

Undocumented tools (may be discoverable via an application blueprint process)


Physical Mainframe Review

Examines system architecture, technical services in use, and analysis of both internal and external services/applications. We can use this information to map your system to your desired target services and architecture.

Existing architecture survey

Architecture diagram evaluation

External applications assessment

Utilities and services assessment

Services overlap within the full application portfolio

Performance, quality, and security baselines and metrics



While the technical review is important, it’s also useful to have an understanding of who on the team is able to maintain and develop on your existing systems. The logic and technical requirements may be different once you’ve established your target architecture.

Survey of staffing (existing and future)

Assessment of team’s working knowledge of applications

Talent assessment within market


As you gather this information, TSRI uses its tools to assess the code, find any code modules/segments within applications that are no longer in use, and generate code-level documentation through a blueprint preview of the current codebase and what a future, modernized codebase might look like. We will then work with you to establish business requirements. Note that while many of these tasks individually take a short time, depending upon the number of applications and the size of your application portfolio, an end-to-end engagement can range anywhere from 1-2 years if your systems have fewer than 10 million lines of code to transform to 4-5 years for much larger portfolios and codebases.




Business case development and financial discovery

Once you have completed a technical analysis and your IT leaders understand your existing systems, it is time to establish your organization’s business cases to modernize your applications and support a modern environment.



Timeframe for project phases and project completion

Market and internal demands

Then vs. now: evolution of your customer and business needs

Modern workflows and accessibility

Security posture


Total cost of mainframe and application ownership

Mainframe operating expenses

Capital expenditures

Amortized costs


Market agility

Business requirements agility

Availability of developers that support legacy systems

While most businesses that rely upon mainframes will need to modernize in one way or another, every organization’s needs will be different. Base your organization’s decisions not just on the flashiest current technologies, but on the methodologies and technologies that will work best for your company today and into the future. TSRI can work with you to complete this checklist assessment to start you on the path of a fully automated mainframe modernization. Contact us now to begin!
