Question 1

Can a platform be migrated without truly understanding it first?

Accepted Answer

Yes, and failing to do so is actually one of the main causes of failure
for modernization projects. Ellipsys automatically reconstructs dependencies,
usage, and processes before any migration takes place.

Question 2

Why do so many projects go over budget?

Accepted Answer

Because the real dependencies, usage patterns, and custom developments
are rarely known before the project starts.
Our probes and parsers automate this analysis phase.

Question 3

Do you need to document a system before modernizing it?

Accepted Answer

No. {openAudit} automatically reconstructs the data lineage,
usage, and technical documentation from the
existing platforms.

Question 4

Can you switch dataviz tools without starting over?

Accepted Answer

Yes. Calculations, business rules and business objects are carried
in SQL by {oa-lake} and its semantic layer, not by the reporting tool.
Power BI, Looker or Superset become interchangeable presentation layers.

Question 5

Why reconstruct ETL processes in SQL?

Accepted Answer

Because SQL has become the common language of modern
analytics platforms. The generated processes feed
{oa-tbx}, our open SQL ETL.

Question 6

Does leaving a legacy ETL create a new dependency?

Accepted Answer

No. Processes are translated into standard SQL and run on {oa-tbx},
an open, containerized SQL ELT. The code stays readable, versionable
and maintainable by your teams, with no proprietary format.

Question 7

What happens to the sequencing and scheduling of your ETL flows?

Accepted Answer

They are carried over automatically. Sequences, dependencies, conditions
and schedules defined in the legacy ETL are converted into Airflow DAGs,
the leading open-source orchestrator, with no manual reconfiguration. If an
external scheduler is already in place (Control-M, for example), it can be kept.
