ISAM / VSAM migration
ISAM/VSAM migration to RDBMS or NoSQL
Our database migration engine DataLiberator supports the automated migration of VSAM, ISAM or other file based legacy databases either on Mainframe or open systems to various RDBMS products like PostgreSql, Oracle, Tibero, Microsoft MSSQL or other. The data access and management concept of legacy applications on such file systems is sometimes closer to a NoSQL implementation than to a relational model, so the overall migration might be more straightforward to a NoSQL solution like MongoDB in some cases. DataLiberator also supports that concept.
Our tool covers automated schema conversion based on COBOL or PL/I copybooks and also using other relevant information of the application source code e.g. REDEFINE.
