Is it easy to learn another ETL software once you know how to use one ETL?

This was one of the questions by a person via LinkedIn.  He wants to know if it's easy to learn another ETL software once you know how to use one ETL tool?

Also if you know one of the Reporting and Analytics tool like SAP BO is it easy to learn another one like MicroStrategy?

My answer: In general, yes, it's easier to learn the second tool in the same category. From own experience, it was quite easy to learn Ab initio after having worked with DataStage, and it was again quite easy to learn BODS after Ab initio and DataStage.  After working with these 3 tools it was quite easy to understand what Pentaho Data Integration (PDI) offers when I led a team which worked with PDI.

Similarly, it was quite easy to pick up MicroStrategy after working with SAP BO.  And similarly other tools like Tableau, Excel, Google sheets, GDS, etc.
