Upgrade your Core Banking System without Performance Problems

We upgrade our devices, such as phones or computers, weekly or as soon as a new version is available. Keeping our data secure and having the latest features available are among the top reasons for these frequent upgrades. These new features come with a price and require the full attention of product companies. They must support older device generations but also not introduce slowdowns or crashes. Still, you might experience massive performance issues after upgrading because the developer might not consider your extraordinary configuration, hardware, and data volume.


If we look at the media, we see change-related issues almost daily across all industries. People are getting scared to change and improve things because of unexpected adverse side effects such as performance problems or software errors.


Changes and upgrades are necessary to make room for the new and prepare your team for the future. It's not a bad idea to introduce continuous product upgrades to avoid technical depth.


Upgrade in T24 will usually involve Globus to TAFJ or TAFC to TAFJ upgrades because of its enhanced facilities in TAFJ. Still, some banks prefer Globus to TAFC or TAFC lower release to TAFC higher release upgrades either due to its simple core banking setup or stability in TAFC releases.

What is the general T24 upgrade process?

1. Current T24 system analysis including creation of functional and non-functional requirements


2. Business/Functional changes to be implemented, such as

· LD/MG to AA upgrade

· Implementation of TPH and FCM for payments

· IRIS and IF implementation for better integration and interfaces design

· TAFC to TAFJ upgrade

· DB2/SQL to Oracle upgrade


3. Technical code changes

· Involves selecting a preferred programming language as per the latest T24 release.

· Infobasic to Componentised/L3 JAVA/Python code conversion

· Code changes as per the functional requirements


4. T24 Environment setup and implementing the functionality and code changes


5. Unit, FT, SIT, Performance and UAT testing.

6. Mock upgrade runs, GO LIVE, and post GO LIVE support.


7. Ensure a proper monitoring from the end user down to the code level of all your T24 transactions to identify and fix issues before anyone is impacted.
