Encouraging organizations to leap forward, Teradata migration has observed an upsurge. However, one of the biggest challenges faced by them is the complexity of the process involved.
Teradata is an intricate system amassed with rich, distinctive SQL syntax. When Teradata migration takes place, the transference of terabytes of data containing tables, codes besides other patented elements happens. The process is far from simple and takes enormous amounts of time. Thanks to the complexities of Teradata, the migration journey is not always smooth and often leads to incompetence.

If your application base is comprised of such codes, SQL, Spark, and other such standardized methods must be availed. You must also have cohorts experienced in translating BTEQ scripts to advance your process further.
