A method includes acquiring network monitoring and analysis (NMA) alarm processing rules residing in flat format data files, transforming the flat format data files into comma-separated values (CSV) files, clustering the CSV files into a plurality of clusters each containing a subset of the CSV files, for a selected cluster, aggregating the subset contained within the selected cluster, so that the subset is transformed into a smaller subset, applying at least one pre-processing technique to the smaller subset, converting the smaller subset of CSV files into JavaScript object notation (JSON) files, executing a generative artificial intelligence technique that takes as an input one of the JSON files and an example network service assurance system (NSAS) policy engine framework (PEF) policy and outputs a code for converting any JSON file into a NSAS PEF policy, and transforming, using the code, the JSON files into NSAS PEF policies.
