IT departments are plagued by legacy applications and often there is a strong demand to modernize the application landscape. As part of the 3rd platform modernizations happening in the industry we see a growing need to handle legacy applications.

Often modernization projects are struggling with legacy data. Trying to migrate legacy data towards a new system leads to lots of challenges; the data model is different in the target application, migrations can lead to invalid data models and can break the new application. This situation gets even more complex when multiple legacy systems are migrated to a single new target system. Because of these complexities, migrations tend to be expensive and time consuming slowing down innovation in the data center.

InfoArchive has a complete different approach to data migration which reduces the costs, the risks and the time it takes to migrate towards new architectures. The approach is simple but under the hood we use several unique technologies that enables you to accelerate your migration.

Here’s how it works:

Assume we have multiple legacy ERP systems and we want to introduce a new SAP system replacing all these legacy applications. Instead of migrating all data to SAP we
instead export all data from the legacy systems to XML records without changing the individual records data fields.

Since we store each legacy record in XML in the No-SQL database of InfoArchive we can augment the source record with a unique SAP key that binds the legacy systems together with the SAP record.

InfoArchive has a unique capability to search across disparate data records with a single query allowing us to retrieve all relevant records with a single query even though have different data structures. These queries can be optimized for high volume concurrent access using Composite Path Indexes. Composite Path indexes allow you to create a single index structure for different record types.

XML also allows us to create a single composite view over the different records and present this in an integrated view in the SAP system.

Does that mean that no data will be migrated to SAP at all? No, typically the migration will focus on the open transactions plus a few months of the most recent data of the most critical business objects. This subset of data is so small that the costs and risk of these migration shrink to a fraction of a full migration.

In summary, InfoArchive offers a unique capability to avoid unnecessary, risky, time consuming and expensive migrations. InfoArchive’s capability to link different records, its composite index structures and its ability to search across different records with a single query and present that in an integrated native view within the SAP system is a unique way to accelerate SAP implementations while reducing its risk.
