Step 4: Test & Deploy
The test and deploy phase begins with the receipt of work packets through the DevOps toolchain as they are delivered from iterative transformation activities in the previous phase. If issues arise, the work packet is passed back to Advanced where we review the code, adjust our tooling, reprocess the work packet, and send it back into the DevOps pipeline to resume testing and deployment. This process repeats until the entire modernised estate has been deployed.
Prior to go-live, Advanced refreshes the target environment by transforming a final snapshot of the mainframe environment to account for changes that have taken place throughout modernisation project as part of normal business operations. Fortunately, since all adjustments and optimisations have been made to the tools and not the target codebase itself, this final refresh can be delivered into production over a weekend, eliminating code freezes.
